The base body (2) and the dummy lens (3) are each composed of a plurality of discs (5, 5'). The invention also relates to a suitable method for manufacturing such a dummy camera (1).

Description

[0001] The invention relates to a dummy camera and a suitable method for manufacturing such a dummy camera.

[0002] Many stores use security cameras to prevent or solve shoplifting. It's common practice to replace at least some of these cameras with realistic replicas for cost reasons. When properly installed, these replicas are virtually indistinguishable from working cameras. Such dummy cameras must be custom-made to match the shape of the real cameras and are therefore usually only used in small quantities; sometimes only a single dummy camera is installed. Manufacturing these dummy cameras is generally complex. While injection molding is a relatively inexpensive method, the production costs for the necessary molds would be disproportionately high for small production runs.

[0003] It is therefore an object of the present invention to provide a camera dummy and a method for producing such a camera dummy, which enables a solution that is quickly modifiable, uncomplicated and as cost-effective as possible with regard to the production of the shape.

[0004] This problem is solved firstly by a dummy camera according to claim 1 and secondly by a method for manufacturing such a dummy camera according to claim 15.

[0005] According to the invention, the dummy camera comprises a base body and a dummy lens arranged on a first side of the base body, hereinafter also referred to as the "top side". Both the base body and the dummy lens are each composed of a plurality of discs.

[0006] Accordingly, in the method for manufacturing the camera dummy, a base body and a lens dummy are each assembled from a plurality of discs. As described in more detail later, the discs of the lens dummy and the base body can preferably be stacked on top of each other in a "assembly direction" using assembly aid systems, aligned relative to each other, and centered. Finally, the lens dummy is positioned on the top side of the base body.

[0007] In the following, a "first assembly direction" refers to the assembly direction of the base body. It is a vector running essentially perpendicular to the disks of the base body, which, in the assembled state of the camera dummy, points from the base body to the lens dummy. Accordingly, a "second assembly direction" is the assembly direction of the lens dummy. It runs essentially perpendicular to the disks of the lens dummy and is directed from the lens dummy to the base body. The disks of the base body and the lens dummy each have an outer contour corresponding to a cross-section of the base body or the lens dummy. The cross-sections each lie in a plane perpendicular to the respective assembly direction. Thus, each disk forms a construction plane of the respective component. By placing the disks together or on top of each other along the respective assembly direction, a planar arrangement of the disks is achieved.When centered and connected to each other, these discs, when properly assembled, create a deceptively realistic replica of a camera to the observer.

[0008] The dummy camera can be integrated into a housing with a domed cover, such as one made of glass or acrylic, just like a real camera. This means that often only certain sections of the dummy lens are visible. The fact that the domed cover is usually slightly tinted further helps to make the dummy camera, constructed from these glass panels, indistinguishable from a real camera. This gives the dummy camera a deterrent effect and makes it very effective for burglary and / or theft prevention, for example, to prevent or reduce shoplifting, or for other purposes such as vandalism prevention, simulated parking surveillance, etc.

[0009] The shape of the discs is easily modifiable, meaning that in principle, any dummy camera can be individually constructed without additional costs. A particular advantage of the disc technology is the comparatively low manufacturing cost. As mentioned, manufacturing the base body and / or the dummy lens using injection molding would be very complex, as molds would first have to be produced for all components. For small production runs, as is the case with dummy cameras, this effort is not worthwhile, making the disc technology a cost-effective alternative to injection molding.

[0010] Further, particularly advantageous embodiments and developments of the invention result from the dependent claims and the following description, wherein the claims of one claim category may also be further developed analogously to the claims and description parts of another claim category and, in particular, individual features of different embodiments or variants may be combined to form new embodiments or variants.

[0011] In principle, any suitably shaped starting material can be used to manufacture the discs. For example, plastic, wood, metal, or glass are possible, with plastic being preferred. In a particularly simple design, at least some of the discs, preferably all of them, are cut from a number of sheets. These sheets can be one or more. Depending on the material, the cutting and / or removal can be carried out using any suitable technique, such as cutting, laser, or milling techniques, most preferably using a CNC (Computerized Numerical Control) milling machine, or the like.

[0012] When cutting the lenses from sheets, virtually any contour can be specified for each lens. If the design of common surveillance cameras used in stores is further developed, only the lens contours of the dummy camera need to be adapted to these design changes. Since the individual lenses of the dummy camera are cut from sheets, the corresponding contour changes can be easily made, for example, in a CAD program or similar software. The laser or milling machine then cuts the adapted contours provided by the CAD program from the sheet(s). Thus, changing the design of the dummy camera is straightforward and can be implemented quickly and without significant effort.

[0013] For a dummy camera, however, not only easily implemented design changes are important. Above all, it should embody the most realistic possible representation of the original camera. To replicate the external shape of an original camera with sufficient accuracy, the glass panes must not exceed a maximum thickness. Otherwise, smaller details, visible to a viewer, might not be resolved. On the other hand, the thickness should not fall below a certain minimum, as otherwise a large number of panes would have to be cut out, aligned relative to each other, and joined together. This would lead to an increase in both production costs and manufacturing time. Therefore, the glass panes of the dummy camera have a minimum thickness of 3 mm, preferably 4 mm.Furthermore, or alternatively, they have a maximum thickness of 10 mm, preferably a maximum thickness of 8 mm, and particularly preferably a maximum thickness of 6 mm. In a particularly preferred embodiment of the camera dummy, the discs have a thickness of preferably 5 mm. However, the discs for the base body and the discs for the lens dummy can also have different thicknesses. In a very preferred embodiment of the camera dummy, the base body has thicker discs than the lens dummy, which can increase stability. The required thickness of the base body for stability can then be achieved with a comparatively small number of discs, so that the number of assembly steps and consequently the production costs are kept comparatively low. The discs of the lens dummy preferably have thinner discs in order to realistically replicate the lens.

[0014] Preferably, at least some of the discs have essentially the same thickness. Small, but negligible, deviations in disc thickness may result from tolerances common in the construction industry. These discs are preferably cut from the same sheet material, most preferably from a single sheet. Most preferably, at least all discs made of the same material are cut from the same sheet. If all sheets are made of the same material, preferably all discs are manufactured from the same sheet, provided its size is sufficient. If the maximum possible number of components can be cut from the same sheet in a single production step, both time and material consumption can be optimized.

[0015] To avoid unnecessary production costs, the number of lenses in the dummy camera should not exceed a certain maximum. Therefore, the base body of a preferred embodiment of the dummy camera has a maximum of 12 lenses, and more preferably a maximum of 8 lenses. For the same reasons, the dummy lens preferably has a maximum of 10 lenses, and more preferably a maximum of 7 lenses.

[0016] Likewise, the number of discs should preferably not fall below a minimum to ensure that the contours of the original camera can still be reproduced accurately enough, as mentioned above. Therefore, the base body preferably comprises a minimum of 2 discs, and more preferably at least 4 discs. The dummy lens preferably has a minimum of 3 discs, and more preferably at least 4 discs. The number of discs in the dummy camera thus preferably falls within a suitable range, which can vary depending on the selected disc thickness. A particularly preferred embodiment of the dummy camera comprises a base body with 5 discs and a dummy lens with 5 discs.

[0017] As described above, preferably at least some of these discs are cut from sheets. All discs are then assembled into a base body and a dummy lens, as explained in more detail below. Finally, the dummy lens is attached to the top of the base body by means of at least one retaining strip, preferably at least two retaining strips.

[0018] In a preferred embodiment of the camera dummy according to the invention, not only a portion of the discs of the base body and / or the lens dummy, but also the retaining bridge, or at least one of the retaining bridges, is cut from a single plate. Preferably, the retaining bridge in question is cut from the same plate as at least a portion of the discs of the base body and / or the lens dummy. To save material, the retaining bridge can, for example, also be cost-effectively cut from a scrap piece between the discs in the plate.

[0019] To connect a retaining bar or bars to the base body, the respective retaining bar can preferably be inserted into the base body. It can then be additionally fixed there, preferably using an adhesive; that is, the retaining bar is advantageously also bonded to a number of the base body's discs. Alternatively, the connection of the retaining bar or bars to the base body can also be a purely adhesive bond. In such a purely adhesive bond, the retaining bar in question can be glued to the disc of the base body located on the top side using a suitable adhesive.

[0020] It should be noted here that the disc of the base body facing the lens dummy in the assembled state of the camera dummy is also referred to as the "cover disc" in the following.

[0021] To allow a retaining clip to be inserted into the base body, at least one insertion opening is provided in the base body to precisely accommodate the retaining clip on at least three sides. The cover plate, at least, has one insertion opening for the retaining clip in question, or several such openings, e.g., two, if multiple retaining clips are to be connected to the base body in this way.

[0022] For the following description, the disk of the base body pointing away from the top side is defined as the "base disk". Similarly, the "base side" refers to the side of the base body on which the base disk is located.

[0023] The following explanations assume the preferred example where the dummy lens is connected to the base body via two mounting brackets. However, these explanations generally also apply to attachments with only one mounting bracket or with more than two, unless explicitly stated otherwise.

[0024] The insertion openings of the discs of the base body, arranged as intended, form insertion holes with defined depths in the base body. The length of the insertion holes runs largely parallel to the axis of the base body, which passes through the centers of the discs. The discs located on the base side do not necessarily have corresponding insertion openings. The insertion holes can therefore preferably be designed as blind holes in the base body, with the hole depths defining the insertion depth of the retaining tabs. Thus, the retaining tabs serve as fastening elements for a positive-locking connection of both the dummy lens to the base body and, if necessary, of several discs of the base body to each other. However, the retaining tabs are not only intended for the simple attachment of the dummy lens to the base body.Rather, they enable, with appropriate coupling of the dummy lens with retaining struts, as will be explained later, a rotatable mounting of the dummy lens.

[0025] In addition to the insertion openings described above, in a particularly preferred embodiment of the camera dummy according to the invention at least some of the discs have further recesses.

[0026] The discs of the base body and / or the dummy lens can preferably each have a contour that deviates from a circular arc, at least in one edge region, preferably a flattened surface. In its intended use, the dummy camera, as mentioned above, is often housed in a casing. This casing usually has a largely cylindrical shape in the area surrounding the base body. Furthermore, the casing typically has a cable outlet in this cylindrical area. In this case, the flattened surfaces of the individual discs of the base body form a cavity between the base body and the casing wall, leaving sufficient space for a cable positioned laterally on the base body. In its intended position, the cable can be routed laterally out of the cable outlet in the casing.In this way, the appearance of the properly mounted dummy camera corresponds to that of a functioning camera to an outside observer. Since the lenses of the dummy camera can be adapted to any design changes of the original camera and / or housing, contours of any other shape are possible instead of flattened surfaces.

[0027] Alternatively, or furthermore, the discs of the base body and / or the lens dummy can each have a recess in at least one edge region that penetrates the entire disc. Preferably, at least two, and more preferably two, opposing edge regions have corresponding recesses, hereinafter also referred to as "centering recesses". These centering recesses can, as described below, preferably serve to center the discs of the base body during assembly.

[0028] Furthermore, at least one, preferably the cover plate of the base body, can have a further recess in a central area. This recess is referred to below as the "lens recess".

[0029] The axis passing through the center points of the lens dummy disc is hereinafter referred to as the "lens axis." If this lens dummy is not inclined relative to the axis of the base body, the lens axis coincides with the axis of the base body. The lens dummy is thus essentially mounted centrally to the cover disc of the base body. As previously indicated and described in more detail below, the lens dummy is preferably rotatably mounted on the base body, i.e., the lens axis can be tilted relative to the axis of the base body. Most preferably, it is rotatably mounted between the aforementioned, preferably two, retaining lugs about a virtual axis of rotation. This axis of rotation is hereinafter also referred to as the "lens axis of rotation."

[0030] The preferred lens recess in the base body allows for larger tilting angles of the dummy lens. When the dummy lens is tilted around the axis of rotation relative to the base body axis, the minimum distance between the dummy lens and the top surface of the base body changes for each angle setting. To enable tilting over the widest possible angular range, the minimum distance must always be greater than zero for all adjustable angles. This distance can be varied by the length of the retaining bar(s) and by the design of the top surface. The central recess in the top surface forms a depression in the top surface of the base body. The clear dimension of this depression is preferably larger than the cross-section of the dummy lens in the plane of the top surface at its maximum angle setting.

[0031] In its intended position, the recess in the cover is located below the dummy lens with respect to the first assembly direction. This allows the dummy lens to preferably partially immerse itself in the recess, depending on the tilt angle. In this way, the lens recess, when the dummy lens is rotatably mounted, allows for relatively large tilt angles of the dummy lens relative to the axis of the base body.

[0032] A rotatable mounting of the dummy lens, as mentioned above, is extremely advantageous for the dummy camera according to the invention. Security cameras used in stores are usually mounted with different lens angles relative to the base, depending on their location and the area to be monitored. If, however, all dummy lenses of the dummy cameras had the same angle regardless of their location, this could easily raise suspicions that they were merely dummies. For this reason, the dummy lenses should preferably also be adjustable with respect to their angle. In a particularly preferred embodiment of the dummy camera, the dummy lens is therefore rotatably mounted on the base, as mentioned, with the rotatable mounting preferably being implemented on at least one support bracket.As mentioned, the mounting is particularly preferably achieved between two largely parallel support struts. The mounting is preferably arranged around the lens rotation axis, which runs essentially parallel to the cover plate.

[0033] Preferably, one or both retaining bridges each comprise a first through-opening, hereinafter also referred to as the "lens mounting opening," in an end region adjoining the lens dummy, the "coupling region" of the retaining bridge (where the respective retaining bridge is coupled to the lens dummy). This through-opening forms the bearing for the rotatable mounting of the lens dummy. A first mounting element for the lens dummy, hereinafter referred to as the "lens mounting element," can be guided through this bearing as an axle or as a kind of axle stub and coupled to the lens dummy. If there is more than one lens mounting element forming the bearing axle, these are arranged on two opposite sides of the lens dummy, preferably at a spatial distance from each other, on the same axis of rotation, the "lens rotation axis."This means the lens axis of rotation runs through the lens mounting holes of the retaining clips. As mentioned previously, the insertion holes in the base body for the retaining clips have defined insertion depths. Inserting the retaining clips into these holes results in both lens mounting holes being the same distance from the top surface of the base body. Since the lens mounting holes form the bearing for the rotating mount of the dummy lens, the insertion depth also defines the largely horizontal orientation of the lens axis of rotation, which runs parallel to the top surface.

[0034] Preferred lens mounting means are, for example, bolts and / or screws. A very simple preferred embodiment of the invention comprises two retaining lugs, through which a screw runs perpendicular to the longitudinal extent of the retaining lugs at each end, i.e., in the coupling area. These screws of the two retaining lugs are each screwed laterally into opposite sides of the lens dummy, so that the lens dummy is mounted essentially centrally between the retaining lugs. This means that, in the non-tilted state of the lens dummy relative to the base body, the lens axis preferably coincides with the base body axis.

[0035] As mentioned, the lenses of the dummy camera can essentially be made from any material suitable for processing. Since plastic is not only easy to work with but also inexpensive and lightweight, the lenses of the dummy camera are preferably made of plastic. Polyvinyl chloride (PVC) and / or polymethyl methacrylate (PMMA), also known as acrylic, are preferably used. PVC represents a comparatively inexpensive option and is therefore preferably used for manufacturing those lenses that are barely visible to an external observer when the camera is set up as intended. These can be, for example, the lenses of the base or the lenses of the dummy lens facing the base, hereinafter referred to as "rear lenses".

[0036] Since original cameras typically have glossy surfaces, a similar surface finish may be desired, at least for the externally visible areas of the dummy camera. Therefore, at least one lens of the dummy camera can have a glossy surface.

[0037] Preferably, this involves a number of lenses of the dummy lens that, when properly mounted, point away from the main body, e.g., when used in a housing, face the housing dome. These lenses are clearly visible to a potential external observer and are therefore referred to below as "viewing lenses." Accordingly, the "viewing side" refers to the side of the dummy lens on which the viewing lenses are located. The viewing lens closest to the housing dome is referred to below as the "front lens." The front lens usually has a central opening, also referred to below as the "viewing window." The viewing window allows a view of the lens adjacent to the front lens. This lens has another, essentially circular opening. This opening serves to simulate the lens aperture of an original camera and is therefore referred to below as the "lens aperture."Accordingly, the term "lens aperture disc" refers to the disc that forms the lens aperture. Through this lens aperture, the viewer sees the disc located behind the lens aperture disc, i.e., the side of the lens aperture disc facing away from the front lens, whose surface simulates the lens glass. This disc is also referred to as the "glass dummy disc" in the following.

[0038] Furthermore, the dummy lens has a disc, preferably located in the central area of ​​the dummy lens, which serves to attach the dummy lens to the mounting brackets. Therefore, it is referred to below as the "mounting disc". Preferably, the mounting disc can also form the dummy lens glass, i.e., in addition to attaching it to the mounting brackets, the mounting disc can also simultaneously serve to advantageously imitate the lens glass of an original camera.

[0039] As mentioned, at least one of the viewing windows should preferably have a glossy surface. Acrylic has glossy material properties. For this reason, at least the front window is preferably made of acrylic glass. Preferably, the lens aperture window and the dummy glass window are also made of acrylic glass. In some cases, the original camera serving as a model for the camera replica has a metallic surface. In these cases, preferably all viewing windows of the camera replica are also made of acrylic to simulate a similarly glossy surface. In other cases, however, the original camera, with the exception of the lens glass, is made of materials with matte surface properties. Then the lens replica may have a front window and a lens aperture window made of PVC. The underlying dummy glass window simulating the lens glass, e.g.,The mounting disc could also be made of acrylic, for example.

[0040] As mentioned at the beginning, suitably designed assembly aid systems can preferably be used to assemble the previously described discs of the lens dummy and the base body as well as the retaining bridges.

[0041] The dummy lens can preferably be mounted using a mounting box. A particularly preferred mounting box has a base surface that is essentially in one plane for placing the lenses. Furthermore, it has a flat, largely level boundary wall on at least two sides that form an essentially right angle with each other, serving as a contact surface. It is therefore a box that is preferably open on at least one side. A centering element in the form of a protrusion is arranged on the base surface at a suitable distance from the boundary walls. As explained above, the front lens of the dummy lens preferably has a centrally located viewing window. The geometric dimensions of the centering element are preferably adapted to the viewing window such that the front lens can be fitted precisely onto the centering element.When assembling the dummy lens, the front lens is placed over the centering body. These two complementary elements together form a contact surface, similar in principle to that of a saucepan and its lid. The centering body thus serves to fix the front lens horizontally. The lens aperture lens is then placed on this lens, followed sequentially by the lenses adjoining the lens aperture lens, all slid horizontally against the two boundary walls. To center the lenses with a smaller diameter than the front lens, additional spacers are positioned on the already centered lenses so that they abut the boundary walls. The spacers are thus held in position by the boundary walls and the already centered lenses.Only then are the individual discs pushed against the placeholders. This centers the discs relative to each other. The discs can then be connected to each other, for example by gluing them together.

[0042] The discs of the base body are preferably mounted using a mounting template. The mounting template comprises a support plate that extends largely in one plane and preferably two centering rods embedded in the support plate. The centering rods extend vertically upwards in a largely straight line, i.e., they form a substantially right angle with the support plate. The centering rods are each arranged on a circle with approximately the same diameter as the base disc, preferably substantially at the endpoints of a chord passing through the center of the circle. As described above, the discs of the base body preferably each have centering recesses in their edge region. These centering recesses are then positioned and shaped to fit the centering rods with considerable precision.During assembly, the base plate of the main body is placed on the mounting plate of the jig so that the centering rods are inserted into the centering recesses. The centering rods prevent the plate from shifting horizontally or rotating. Subsequently, the plates in the first assembly direction are positioned one after the other between the centering rods in the same manner. This aligns the plates of the main body relative to each other along the edges of the recesses. As with the plates of the dummy lens, the plates of the main body can also be connected to each other.

[0043] There are various ways to connect the discs of the base body and / or the dummy lens. Preferably, at least two adjacent discs of the base body, i.e., those lying against or on top of each other, are glued together. Preferably, all discs of the base body are glued together. Likewise, preferably at least two, but preferably all, adjacent discs of the dummy lens can be glued together. Other connections are also possible as an alternative or in addition to the adhesive connection, for example, a screw connection. Compared to screwing, however, gluing is a significantly simpler and more cost-effective solution. Various fastening methods, such as gluing and screwing, etc., can also be combined.

[0044] The finished dummy lens can then be coupled to the mounting brackets, as mentioned, e.g., positioned between the mounting brackets, and the mounting brackets inserted into the slots of the base body. Optionally, the mounting brackets can be additionally glued, preferably at their end facing the base, i.e., glued into the slots. Alternatively, the mounting brackets can first be positioned in / on the base body, and then the dummy lens can be coupled to the mounting brackets.

[0045] The dummy camera assembled in this way should preferably be able to be attached to a suitable location as easily as possible, just like a real camera. A preferred embodiment of the dummy camera therefore includes means for attaching the dummy camera to any suitably positioned object, such as a wall, a bracket, or a post. Preferably, the entire dummy camera, for example, the base body, can itself be rotatably attached to the object, preferably at the base of the base body.

[0046] Preferably, the fastening can be carried out centrally, as described in more detail below, i.e. along the axis of the base body running through the respective centers of the disks of the base body.

[0047] Such a mounting can be achieved in various ways. Preferably, the dummy camera can have a second mounting device, hereinafter referred to as the "base mounting device".

[0048] The base fastener is preferably a nut. It preferably has a common internal thread for fastening purposes, most preferably an M6 thread. This allows the base fastener to be coupled to a mounting arm of a conventional camera bracket, as explained below. Alternatively, the base fastener could also be a threaded rod or screw with which the dummy camera can be screwed onto a nut located on the object. However, other types of base fasteners are also conceivable, e.g., magnetic holders, adhesives, etc., or combinations of the aforementioned base fasteners.

[0049] The base fastener, e.g., the nut, threaded rod, or screw, can penetrate at least some of the washers of the base body, most preferably at least the base washer facing the base and a number of the washers adjoining the base washer. For this purpose, the base washer can have a second through-opening for the base fastener. This through-opening is hereinafter referred to as the "base through-opening." However, it is also possible that a plurality of the washers adjoining the base washer can have such a base through-opening.

[0050] These base through-holes each have an approximate minimum diameter of 2 mm and an approximate maximum diameter of 10 mm, particularly preferably 4 mm. The base through-holes are preferably located in a central area of ​​the disc to allow the central passage of the base fastener. The central area comprises the sections arranged around and on the axis of the base body. When the discs of the base body are assembled, the base through-holes form a channel for the base fastener, such as a nut or threaded rod.

[0051] The basic fastening element, for example the nut or the threaded rod, most preferably has a head which is located inside the base body.

[0052] To accommodate the head, a disk of the base body preferably has a central first opening, hereinafter also referred to as the "chamber recess." This disk containing the chamber recess is preferably arranged in an inner region of the base body, which includes the inner disks of the base body. The inner disks of the base body are all disks except the base disk and the cover disk. Thus, the chamber recess, together with the disk adjoining it in the first assembly direction, forms a chamber for accommodating the head of the base fastener. This design has the advantage that the chamber for the base fastener can be easily cut out of a disk of the base body. Depending on the type and size of the base fastener, the chamber dimensions can therefore also be adjusted by increasing or decreasing the diameter of the chamber recess accordingly.Similarly, if the height of an original camera needs to be increased or decreased, only an additional disc needs to be inserted or a disc removed to adjust the dummy camera. The chamber recess remains unaffected. The chamber recess has an approximate minimum diameter of 4 mm and a maximum diameter of 10 mm, preferably 6 mm. From the chamber recess, the (through) channel for the base mounting element can then extend, preferably along the axis of the base body, to the base side.

[0053] The base fastener can preferably be, for example, a T-nut with a claw-shaped underside and a collar-like head. The T-nut can be inserted into the base body during its assembly. Insertion of the T-nut preferably takes place after the washer, which has the chamber recess, has been centered and secured. First, the threaded portion of the T-nut is inserted through the through-channel, which adjoins the chamber recess opposite the first assembly direction. The head of the T-nut is now received in the chamber recess. The insertion of the base fastener thus occurs essentially antiparallel to the first assembly direction and preferably centrally, i.e., along the axis of the base body.

[0054] Preferably, the T-nut is then driven into the disc adjoining the underside of the head or collar. The thread of the T-nut is now largely aligned along the axis of the base body, with the threaded opening facing away from the collar towards the base. A screw or threaded rod, for example for coupling to a mounting arm, can then be inserted from the base. The screw can then be threaded into the thread of the T-nut and tightened. As the screw is tightened, it engages the internal thread of the T-nut, so that the T-nut, with its prongs, works itself evenly further into a disc of the base body adjoining the collar. In this way, the dummy camera can be advantageously attached to another object.

[0055] Particularly preferred are the discs penetrated by the base fastening element, e.g., the T-nut, preferably additionally connected to one another. For example, these discs facing the base can be screwed together. This allows for an extremely stable fastening of the dummy camera, for example, to an M6 threaded rod.

[0056] As explained above, the dummy camera according to the invention can thus be advantageously attached to any object, depending on the respective spatial conditions. Depending on the area to be monitored, it is possible, as mentioned, to attach the dummy camera in any way, e.g., to a building or room ceiling, an interior or exterior wall, a post, and / or any other support.

[0057] The invention is explained in more detail below with reference to the accompanying figures and exemplary embodiments.

[0058] Fig. Figure 1 shows the disc-like structure of the camera dummy 1. The camera dummy 1 essentially comprises a base body 2 and a lens dummy 3, which is arranged on the base body 2 at a distance from it by means of two retaining struts 4. The lens dummy 3 is rotatable relative to the base body 2 about a lens rotation axis D and is slightly tilted in this position. Fig. Figure 5 shows the camera dummy 1 in cross-section, but with a lens dummy 3 aligned parallel to the base body 2.

[0059] The base body 2 and the dummy lens 3 each have a plurality of flat disks 5, 5'. The disks 5 and 5' are, as will be shown later, Fig. 6 and Fig. As will be explained in section 7, the discs are each laid flat on top of one another using a suitable assembly method and fastened to each other, e.g., by gluing and / or screwing. The discs 5' of the lens dummy 3 and the discs 5 of the base body 2 each have geometries such that, when connected to each other, they form an image of an original camera that is as true to life as possible.

[0060] The contours of the individual disks for the base body 2 are shown in the Fig. 3a to 3f are shown. This shows Fig. 3a the base disc 51, which is furthest away from the lens dummy 3, i.e. the one in Fig. 1 bottom disc 51. Fig. Figures 3b to 3e show the inner disks 52 to 55 of the base body 2 adjoining the base disk 51. Fig. 3f shows the cover plate 56 of the base body 2 pointing towards the dummy lens 3.

[0061] The Fig. Figures 4a to 4e show the contours of the individual discs for the dummy lens 3. Fig. Figure 4a shows the front lens 51' of the dummy lens 3. In a state according to Fig. 5, in which the lens dummy 3 is aligned parallel to the base body 2, the front disc 51' is the disc that is furthest away from the base body 2. Fig. 4b shows the in Fig. 5 lens opening disc 52' arranged under the front glass 51' of the dummy lens 3. In Fig. 4c shows the mounting disc 53' for attachment to the retaining struts 4, which in the illustrated embodiment, as explained below, is also used to simulate the lens glass of an original camera and therefore also serves here as a glass dummy disc 53'. Fig. 4d and Fig. Figure 4e shows the rear discs 54' and 55' of the dummy lens 3, which form the part of the dummy lens 3 that connects to the side of the mounting disc 53' facing the base body 2.

[0062] As mentioned, the shapes of the lenses are partly due to the need to adapt them to the shape of the original camera. However, some contour features are also functionally determined, and these will be explained in more detail later.

[0063] The discs 5 of the base body 2 (hereinafter also referred to as base body discs 5), the discs 5' of the dummy lens 3 (hereinafter also referred to as lens discs 5'), and the retaining tabs 4 are each cut from sheets. Since they each have the same thickness of approximately 5 mm, they can partially be cut from the same sheet. Plastic sheets are used as the starting material, and depending on the function of the discs 5, 5', these may be sheets made of PVC or PMMA. Some of the discs 5, 5' of the dummy camera 1, which is housed in a casing 18, are, as shown in Fig. 2 are visible from the outside, but not or hardly visible. These discs 5 of the base body 2 and the rear discs 54', 55' of the dummy lens 3 facing the base body 2 are therefore made of the more cost-effective PVC. For the front disc 51', which is clearly visible to an external observer, as well as the lens aperture disc 52' and the dummy glass disc 53', PMMA is used to simulate the glossy surface of an original camera.

[0064] As mentioned above, the dummy lens 3 is rotatably mounted on the base body 2 between the two retaining struts 4. This is also shown in the cross-section of the dummy camera 1. Fig. 5, clearly visible, serve for the rotatable mounting of the dummy lens 3, preferably two screws 10. These are guided through two lens mounting openings 8 at one end of the retaining struts 4 and screwed into mounting surfaces 22 of the mounting disc 53'. As shown in Fig. As shown in Figure 4c, the mounting surfaces 22 are designed as the sides of two bay-like projections 38 extending away from the center of the mounting disc 53'. The bay-like projections 38 are arranged in substantially opposite edge regions of the mounting disc 53' and their mounting surfaces 22 have a planar extent and extend largely in one plane.

[0065] The screw connection of the retaining brackets 4 to the mounting surfaces 22 takes place along the above lens rotation axis D, which runs through the lens mounting openings 8 of the retaining brackets 4 and through the center of the mounting disc 53' ( Fig. 1) The dummy lens 3, which is thus mounted essentially centrally between the two support struts 4, can therefore be rotated about the lens axis D.

[0066] To attach the retaining webs 4 to the base body 2, the latter has two insertion holes 37, which are arranged diagonally opposite each other, centered around the base body axis G (see Fig. 1 and Fig. 5) This ensures that the dummy lens 3, which is mounted essentially centrally between the retaining struts 4, is positioned above the center point of the cover plate 56 such that, in the non-tilted state of the dummy lens 3 relative to the base body (as in Fig. 5) the objective axis O and the base body axis G are essentially coaxial.

[0067] Fig. Figures 3a to 3f show that, with the exception of the base disk 51 ( Fig. 3a) in all further discs 52, 53, 54, 55, 56 ( Fig. 3b to 3f) of the base body 2 insertion openings 11 are present, which in the assembled state form the insertion holes 37 in the base body 2 (see also Fig. 5) As from Fig. As shown in Figures 3b to 3f, the two insertion openings 11 in each of the discs 5 are arranged essentially diagonally opposite each other and centered around the disc centers of the base body 2, corresponding to the desired position of the insertion holes 37 in the base body 2. Since both insertion holes 37 have essentially the same depth, they define, as already mentioned, the insertion depth of both retaining lugs 4 in the base body 2. Thus, the lens mounting openings 8 of the retaining lugs 4 are also each at the same distance from the cover disc 56 of the base body 2. This ensures that the lens rotation axis D runs largely parallel to the cover disc 56 of the base body 2, as desired.

[0068] The dummy lens 3, positioned as described above, is rotatable around the lens axis D such that the adjustment range of the tilt angle α of the lens axis O of the dummy lens 3 relative to the body axis G of the base body 2 is as large as possible. The possible swivel range of the dummy lens 3 depends on the distance of the swivel circle of the dummy lens 3 from the top surface 6 of the base body 2. For the desired maximum angle, this distance must not be less than zero. This distance can be determined during the construction of the dummy camera 1 by the length of the retaining tabs 4 or their insertion depth into the base body 2. Furthermore, with a constant insertion depth, the distance can also be adjusted as described in Fig. 1 shown by a suitably shaped recess in a central area of ​​the cover 6. Such a recess in the cover 6 of the base body 2 is achieved by the lens recess 9 of the cover plate 56. The length and width dimensions of the lens recess 9 should be chosen such that the dummy lens 3 can be partially accommodated in it at sufficiently large tilt angles relative to the base body axis G. As shown in Fig. As can be seen in 3f, this lens recess 9 in the cover plate 56 of the base body 2 is so large that the cover plate 56 is reduced to a relatively (to the total extent of the cover plate 56) narrow frame.

[0069] As in the Fig. 1 and Fig. As can be seen in Figure 3, the base body discs 5 have further recesses in addition to the lens recess 9. Specifically, the base body discs 5 each have centering recesses 7 in largely opposite edge regions (in Fig. 1 front right and opposite rear left). These centering recesses 7 each have a largely semicircular cross-section parallel to the plane of the disk. The centering recesses 7 run parallel to the axis G of the base body and each penetrates the entire disk 5. In the intended assembled state, the centering recesses 7 of adjacent disks 5 connect to one another, thus forming centering channels. These centering channels run along the first assembly direction through the entire edge region of the base body 2. As described below, the centering channels serve to center the base body disks 5 during assembly.

[0070] Furthermore, the base body disks 5, as also shown in Fig. 1 and Fig. Figure 3 shows a flattening 12 in an area located at the edge. Are all base body disks 5 and lens disks 5' as well as the retaining webs 4 correspondingly Fig. 1. If the components of the camera dummy are centered and connected as intended, this construction can be housed in a casing 18. Fig. Figure 2 shows the dummy camera 1 according to Fig. 1, however rotated by 180° around the base body axis G and integrated into the housing 18.

[0071] The flattened areas 12 in the base body discs 5 create a cavity 21 between the base body 2 and the housing 18. The dimensions of the flattened areas 12 are chosen such that the cavity is large enough to accommodate a standard cable for connecting common security cameras. In the intended assembly state, such a cable is placed in this cavity and led out of the housing 18 through the cable outlet 20. This cable is typically an RJ45 cable, as this cable type is also used to supply power and data to actual cameras.

[0072] As in the Fig. 1, Fig. 4a and Fig. As shown in Figure 4b, some of the lens discs 5' also have cutouts 23 and 24. These cutouts 23 and 24 essentially serve to create a reproduction of the front view of the lens of an original camera that is as realistic as possible.

[0073] The dummy lens 3 comprises, as its uppermost disc (i.e., the one facing the viewing side 35), a front disc 51' with a centrally arranged viewing window 23. The lens aperture disc 52', which is attached to the front disc 51', can be seen through the viewing window 23. The lens aperture disc 52' simulates the lens aperture of an original camera by means of the central lens aperture 24.

[0074] To construct the base body 2, the base body discs 5 are preferably arranged in a construction direction A running from the base disc 51 to the cover disc 56 (see Fig. 5) laid on top of each other from bottom to top and connected,

[0075] Fig. Figure 7 illustrates the assembly procedure of the base body 2 in an assembly template 29, which can be used during assembly for the intended centering of the base body discs 5. Fig. 7a and Fig. Figures 7b each show the same assembly template 29 schematically in a central top view, but in different assembly steps of the basic body 2.

[0076] In Fig. Figure 7a shows the mounting template 29 without the supporting base plates 5. The mounting template 29 has a support plate 30 that is largely flat, taking into account the material-specific surface properties. The support plate 30 has a largely square shape and extends substantially parallel to the plane of the drawing. The support plate 30 can be made of any suitable material, for example, plastic, metal, or wood-based material. Preferably, the support plate 30 is a particleboard. Furthermore, the mounting template 29 comprises two centering rods 31, which are inserted perpendicularly into the support plate 30 and / or screwed, glued, or otherwise suitable connected to it. The centering rods 31 are substantially cylindrical, with a radius corresponding to the centering recesses 7.The longitudinal axes of the centering rods 31 are each arranged on a circle with the radius of the base plate 51 and point perpendicularly out of the plane of the drawing. The centering rods 31 are positioned essentially opposite each other, at the endpoints of the central axis Z. Furthermore, the assembly template has two recessed grips 32 for ergonomically convenient removal of the fully assembled base body. The centers of the recessed grips 32 are also located on the previously described circle, but rotated 90° relative to the central axis Z of the centering rods 31.

[0077] Fig. Figure 7b illustrates the assembly procedure of the base body discs 5. The assembly direction A (compare Fig. 5) here points perpendicularly out of the plane of the drawing. In the following, the term "top" in connection with the assembly of the base body 2 refers to positions in the assembly direction A, while "bottom" refers to positions opposite the assembly direction. The base disc 51 is placed on the support plate 30 such that the centering rods 31 engage laterally in the centering recesses 7. In the same way, the next disc 52 of the base body 2, which follows in the first assembly direction A, is placed on the base disc 51. The centering rods 31 align the edges of the centering recesses 7 with each other, so that the centering recesses 7 form a channel penetrating the base body 2. In this way, the discs 51 and 52 are aligned relative to each other. The two discs 51 and 52, thus centered, are joined together during the assembly process, for example, by means of an adhesive and / or screw connection.

[0078] As the Fig. 3a and Fig. As shown in Figure 3b, the two discs 51 and 52 each have a centrally located base through-hole 13. After the discs 51 and 52 are mounted, these openings 13 are aligned one above the other, forming a channel for the base fastener 15, in this case a T-nut 15 with an internal thread 16. This T-nut 15 is simply inserted or driven in from above through the through-holes 13. Claws on the underside of a collar-shaped head 17 of the T-nut 15 engage with the disc 52 below, thus securing the T-nut 15 against rotation about the thread axis of the internal thread 16. The nut used here is a standard M6 T-nut 15.

[0079] The washer 53, which is next placed centered over the two washers 51, 52 and again attached to the underlying washer 52, also has a central opening 14, hereinafter referred to as chamber recess 14. This is concentric to the through-openings 13 of the underlying washers 51, 52, but is larger than these openings 13 and thus forms a chamber for the head 17 of the insert nut 15.

[0080] Thus, the base body 2 has a threaded opening on its base side 36, which is standard for cameras, for connection to a standard camera mount (see Fig. 5) This allows the dummy camera to be easily attached during later installation at its intended location (see Fig. 8).

[0081] Next, the remaining discs 54, 55, 56 of the base body 2 are placed in the assembly direction as described previously, centered, and connected to each other. Once all discs 5 of the base body 2 are connected to each other, the base body 2 can be removed from the mounting template 29 using the grip recesses 32.

[0082] Similarly, to construct the dummy lens 3, the lens discs 5' are placed on top of each other and connected, but here starting from the front disc 51' to a final rear disc 55' in a (second) assembly direction A', which in the later assembled state of the dummy camera 1 runs opposite to the (first) assembly direction A of the base body 2 (see Fig. 5).

[0083] Fig. Figures 6a to 6c schematically show a preferred mounting aid system for the dummy lens 3, each in different mounting steps.

[0084] Thus, in Fig. Figure 6a shows a top view of an assembly box 25, which essentially comprises a base 28, a centering body 27, and two boundary walls 26 as contact surfaces. The base 28 has a surface extending in the plane of the drawing. The edges of the base 28 each form a right angle with each other. Along two of the corners (in Fig. At each of the intersecting edges of the base 28 (see figure 6a, top right), a boundary wall 26 extends, the inner surfaces of which, facing the base, each form contact surfaces 26f for mounting. The boundary walls 26, or contact surfaces 26f, extend at right angles to the base 28 with a suitable height extending out of the plane of the drawing. Advantageously, the height of the contact surfaces 26f corresponds at least to the total thickness of the superimposed lens discs 5'. It is therefore essentially a box open on two sides of the base 28 and in the direction of the viewer. A centering body 27 is also arranged on the base 28 at a suitable distance from the contact surfaces 26f.

[0085] The centering body 27 is essentially in the shape of a cuboid, the height of which is less than or at most equal to the thickness of the windshield 51'. Its cross-section corresponds essentially to that of the viewing window 23 of the windshield 51'. The tolerances are chosen such that the windshield 51' can be fitted onto the centering body 27 with the greatest possible precision (see Fig. 6b). By accommodating the centering body 27 in the viewing window 23, the front lens 51' is centered, and horizontal slippage and / or rotation of the front lens 51' is prevented. The center of the centering body 27 is located at a distance from both contact surfaces 26 corresponding to the radius of the lens aperture disc 52'. Other shapes of the centering body 27 are also possible, provided that a centered fixation of the desired front lens is achieved.

[0086] Following the front window 51', the lens aperture window 52' is located in the assembly direction A', as shown in Fig. 6c, shown on the right, is placed on the front disc 51'. After placing the lens aperture disc 52', it is pushed against both contact surfaces 26f. Due to the appropriately chosen distance of the centering body 27 from the contact surfaces 26f, the center point of the lens aperture disc 52' is now located above the center point of the front disc 51' relative to the second assembly direction. In the same way, the mounting disc 53' and then the rear discs 54', 55' of the dummy lens 3, pointing away from the viewing side 35, are arranged in the second assembly direction A'. Since the mounting disc 53' and the rear discs 54', 55' have a smaller diameter than the lens aperture disc 52', thin, appropriately cut plates, e.g.,Made of plastic, wood, metal, or the like, these plates are used in the manner of gauges and are placed as spacers against the mounting surfaces 26f, so that the sides of the plates facing away from the mounting surfaces 26f serve as mounting surfaces for the respective lenses 53', 54', 55' (not shown in the figures). During assembly, all lens lenses 5' are connected to each other, preferably by gluing.

[0087] In Fig. Figure 2 shows, as already mentioned, the dummy camera 1, which is mounted in a housing 18 as intended. The dummy camera 1 is largely covered by the housing 18. The housing dome 19 is made of a transparent material, e.g., Plexiglas or glass. Since the dome 19 is tinted, the dummy lens 3 and the end portion of the support struts 4 facing the dome are only visible as outlines from the outside. The front lens 51' facing the dome is particularly visible. As mentioned previously, the front lens 51' is made of acrylic and thus, due to its glossy surface properties, creates a deceptively realistic image of an original camera.

[0088] Depending on the ceiling height and the design of the business premises, different mounting methods for the dummy camera are possible. For example, in areas with relatively low ceilings, the camera can be screwed directly into a suspended ceiling, or in areas with high ceilings, it can be mounted to the existing light strip. For the latter option, brackets are typically used that are fixed around the light strips. Fig.Figure 8 schematically shows the attachment of the dummy camera 1, housed in the casing 18 with dome 19, to such a holder. The mounting arm 33 of the holder, typically an M6 threaded rod, is visible. The threaded rod 33 is screwed into the dummy camera 1 using the previously described insert nut 15, or the dummy camera 1 is screwed onto the end of the threaded rod 33 using the thread 16 of the insert nut 15. Thus, the dummy camera 1 can be screwed centrally to the mounting arm 33 along the axis G of the base body. In this exemplary embodiment, the base body is also rotatably attached to the threaded rod 33, so that the entire dummy camera 1 is rotatably mounted about the axis G of the base body.Since dummy cameras mounted in this way are usually much more visible than dummy cameras screwed into a suspended ceiling, for example, a cable 34 is additionally connected to the dummy camera to simulate a real camera.

[0089] Since the camera dummy described in detail above is merely an exemplary embodiment, it can be modified by a person skilled in the art in a variety of ways without departing from the scope of the invention. For example, the base body—unlike the one shown in the figures—can preferably comprise only five discs instead of six. For instance, one of the inner discs of the base body could be omitted if another disc of the base body were slightly modified. For example, the disc with the chamber recess could be omitted, and a corresponding chamber recess could be provided in the next disc in the direction of the lens dummy. Alternatively, it would be conceivable to remove the latter disc altogether. Furthermore, the use of the indefinite articles "a" or "an" does not preclude the possibility that the features in question may be present multiple times.
