Description

surveillance camera device

[0001] The present invention relates to a surveillance camera device with improved ease of installation and assembly.

[0002] A surveillance camera is a device installed on the ceiling, walls, or other structures of a building to capture movement within a designated area. Surveillance cameras can be broadly classified into fixed surveillance cameras, in which the direction of the lens is fixed, and rotating surveillance cameras, in which the direction of the lens rotates within a predetermined angle.

[0003] Since fixed surveillance cameras have a fixed shooting angle and lens direction, the installation location must be carefully selected to capture the desired space. Once the installation location is selected, the camera housing housing, which houses the camera module, is positioned (e.g., by rotation) to correspond to the desired imaging area. Subsequently, with the camera housing fixed, an assembly process using casing components is performed, and finally, the assembled surveillance camera unit is installed on a pre-set target object. Despite the complexity of this installation process, most surveillance camera installations are performed by a single operator. As the complexity of the installation process can lead to installation defects and device failures, the design of casing components that facilitate assembly and installation is required.

[0004] The objective of the present invention is to provide a surveillance camera device with improved ease of installation and assembly, and in particular, to provide a surveillance camera device in which case members constituting the device can be easily aligned and assembled in correspondence with a desired imaging area when installing the surveillance camera device.

[0005] The technical problems that the present invention aims to solve are not limited to those described above, and other unmentioned problems can be clearly understood by those skilled in the art from the description of the invention below.

[0006] A surveillance camera device according to one embodiment of the present invention may include: a camera housing in which a camera module is accommodated; a connecting cover disposed to surround at least a portion of the camera housing and restricting downward displacement of the camera housing, and including a cut portion that exposes at least a portion of the camera housing; and a bottom cover installed on the inner side of the connecting cover and configured to allow at least a portion of the camera housing to be seated thereon, thereby restricting upward displacement of the camera housing. The bottom cover may be installed on the connecting cover to allow movement in the vertical direction within a preset range.

[0007] A surveillance camera device according to one embodiment of the present invention may further include position adjustment units installed at a plurality of locations on the inner surface of the connecting cover. The position adjustment units may include an elastic member that detachably fastens the bottom cover to the internal space of the connecting cover. The elastic member may allow the bottom cover to be drawn into the internal space of the connecting cover by elastic deformation caused by an external force, and may restrict the bottom cover drawn into the internal space of the connecting cover from moving outward by restoration upon release of the external force.

[0008] According to one embodiment of the present invention, the elastic member comprises a first plate and a second plate that is bent and extended from the first plate and has a free end, and may be configured such that the gap between the first plate and the free end of the second plate changes by an external force and the release of the external force.

[0009] According to one embodiment of the present invention, the position adjustment member may further include a fixing pin that is fixed to the inner surface of the connecting cover and extends along the vertical direction. The bottom cover includes a fixing hole formed to be retractable into and retractable from the fixing pin, and relative rotation with respect to the connecting cover may be restricted when the fixing pin is retracted into the fixing hole.

[0010] A surveillance camera device according to one embodiment of the present invention may further include a cushioning member fixed on the bottom cover and configured to be seated and contactable by at least a portion of the camera housing. The bottom cover may include an open hole through which a cable extends. The cushioning member may include an open hole through which the cable extends and which communicates with the open hole.

[0011] According to one embodiment of the present invention, the incision may include a first portion that is open toward the downward and a second portion that extends from the first portion and is open toward the forward. The cushioning member may further include an expanded opening hole located relatively rearward and communicating with the opening hole.

[0012] A surveillance camera device according to one embodiment of the present invention may further include a base detachably connected to the connection cover. The base may include a first body fixedly mounted on a preset fixed body; and a second body connected to the first body and configured to be retractable into the connection cover. When the connection cover and the base are connected, the second body may press the camera housing through the bottom cover by contacting the bottom cover, or press the camera housing by directly contacting the camera housing.

[0013] According to one embodiment of the present invention, the connecting cover may include: a seating portion having a shape protruding from the inner surface toward the internal space and having a seating surface that has an inclination as the thickness gradually increases from the bottom to the top; and a screw hole formed through the thickness and positioned opposite to the seating portion along the front-rear direction, into which a screw is fastened. The second body may include a side surface that has an inclination corresponding to the seating surface and abuts the seating surface when the connecting cover and the base are mutually fastened. The screw hole may expose at least a portion of the side surface of the second body when the connecting cover and the base are mutually fastened.

[0014] The present invention provides a casing member assembled in a novel manner, thereby allowing the viewing direction of the camera corresponding to the desired imaging area in various installation environments to be easily adjusted, and in this state, the surveillance camera device can be assembled and installed with only simplified fastening operations.

[0015] The effects obtainable from the present invention are not limited to those mentioned above, and other unmentioned effects will be clearly understood by those skilled in the art from the description below.

[0030] Referring to FIGS. 1 and 2, a surveillance camera device (10) according to a preferred embodiment of the present invention may include a camera housing (100), a connecting cover (200), a bottom cover (300), and a base (500).

[0031] The camera housing (100) can accommodate a camera module inside. The camera module can acquire an image (or video) of the imaging area while covering a preset imaging area. The camera module may be configured to move automatically or manually along a certain path, but is not limited thereto. The camera housing (100) may also accommodate various components required to perform auxiliary functions of the surveillance camera, such as a microphone module, inside. The camera housing (100) can perform the function of protecting the camera module inside from external dust, moisture, etc.

[0032] The camera housing (100) may have a curved shape having a predetermined curvature in at least a portion. The camera housing (100) may have a spherical shape in at least a portion. One end of the camera housing (100) may include a window (110). The window (110) may be formed of a transparent material, and the camera module may acquire an image of a preset imaging area through the window (110). Preferably, the area where the window (110) is formed may have a flat shape, but is not limited thereto.

[0033] The camera housing (100) may include a through hole (120) through which at least one cable (130) passes. The cable (130) may be connected to at least some of the components housed within the camera housing (100), including a camera module, to perform the function of transmitting and receiving power and signals. The cable (130) may extend to the outside of the camera housing (100) through the through hole (120). Preferably, a window (110) may be located at one end of the camera housing (100), and a through hole (120) may be located at the other end of the camera housing (100).

[0034] The connecting cover (200) accommodates the camera housing (100) and may include an internal space open toward the top to allow the camera housing (100) to be inserted and withdrawn. The connecting cover (200) may be provided to wrap around at least a portion of the perimeter of the camera housing (100). The connecting cover (200) may restrict downward displacement of the camera housing (100) accommodated in the internal space.

[0035] The connecting cover (200) may include an opening (210) that opens the interior. The connecting cover (200) may expose at least a portion of the camera housing (100) through the opening (210). The size of the opening (210) may be set to limit downward displacement of the camera housing (100) housed inside the connecting cover (200). The window (110) of the camera housing (100) may be exposed to the outside through the opening (210), and the camera module may acquire an image of a preset imaging area through the opening (210). For example, the opening (210) may include a first portion that opens downward and a second portion that extends from the first portion and opens forward. When installing a surveillance camera, the user may move (rotate) the camera housing (100) within a preset range corresponding to the desired imaging area. The movement of the camera housing (100) can be performed within the range where the window (110) is exposed by the first and second parts of the cut portion (210).

[0036] The connecting cover (200) may restrict and / or constrain the movement of the camera housing (100) housed in its internal space. For example, the internal space of the connecting cover (200) may include a contact area where the connecting cover (200) becomes narrower towards the bottom. In the contact area, at least a portion of the inner surface of the connecting cover (200) and at least a portion of the outer surface of the camera housing (100) may come into mutual contact (e.g., surface contact). The movement (rotation) of the camera housing (100) housed in the connecting cover (200) may be restricted by frictional force as it comes into contact with the connecting cover (200). Conversely, relative movement (rotation) of the camera housing (100) relative to the connecting cover (200) in a preset direction may be permitted when the camera housing (100) is not in contact with the connecting cover (200). The preset direction may include a rotate direction, a tilt direction, and a pan direction.

[0037] The connecting cover (200) may include a protrusion (220) that protrudes from the inner surface toward the internal space. There may be multiple protrusions (220), and the multiple protrusions (220) may be formed spaced apart from each other in the circumferential direction. The protrusion (220) may contact the camera housing (100) inserted into the connecting cover (200) to guide the position of the connecting cover (200). The protrusion (220) may make surface contact with the camera housing (100) to restrict the movement (rotation) of the camera housing (100).

[0038] Referring further to FIG. 3, the bottom cover (300) is accommodated in the internal space of the connecting cover (200) and can be detachably fastened to the inside of the connecting cover (200). The bottom cover (300) can be provided to accommodate at least a portion of the camera housing (100). The bottom cover (300) supports the camera housing (100) while fastened to the connecting cover (200) and can restrict upward displacement of the camera housing (100).

[0039] The bottom cover (300) may have a plate shape having a predetermined thickness in the vertical direction. The bottom cover (300) may include an open hole (310) that penetrates in the vertical direction. The open hole (310) may be located in the center of the bottom cover (300) and may function as an extension path for the cable (130). The bottom cover (300) may have a shape corresponding to the internal space of the connecting cover (200), and preferably, may have an annular plate shape or a disc shape.

[0040] The bottom cover (300) may further include an expansion open hole (315). The expansion open hole (315) may be laterally connected to the open hole (310) and may function as an extension path for the cable (130). The area of ​​the bottom cover (300) where the expansion open hole (315) is formed may be referred to as an expansion area. In the expansion area, the width of the bottom cover (300) may be formed thinner compared to the width in other areas as the expansion open hole (315) is formed. The expansion open hole (315) may be positioned in the reverse direction (e.g., rear) of the opening direction (e.g., front) of the cut portion (210) when the bottom cover (300) is fastened to the connecting cover (200). This may mean that interference between the cable (130) and the bottom cover (300) is minimized by the expansion open hole (315). More specifically, the cut portion (210) located at the front is a part that exposes the window (110) located at one end of the camera housing (100), so the cable (130) located at the bottom of the camera housing (100) is located relatively at the rear. As described above, when installing the surveillance camera device (10), the camera housing (100) is moved to correspond to the desired imaging area, and at this time, the cable (130) located at the rear also moves together, and interference with the bottom cover (300) may occur.

[0041] To prevent this, the bottom cover (300) according to a preferred embodiment of the present invention may include an expansion open hole (315) located relatively rearward. Position adjustment of the camera housing (100) may be performed along the shape (first part and second part) of the cut portion (210) within the range where the window (110) located at one end corresponding to the desired imaging area is exposed by the cut portion (210). That is, the range of movement (rotation) for position adjustment of the camera housing (100) may correspond approximately to the shape (first part and second part) of the cut portion (210). Accordingly, since the cable (130) located at the other end of the camera housing (100) will be moved relatively rearward, the expansion area may be set rearward considering the range of movement of the cable (130), and the size of the expansion open hole (315) may also be set accordingly. The expanded area where the expanded open hole (315) is formed may not actually be a part that supports the camera housing (100), so the function of the bottom cover (300) may not be reduced by the expanded open hole (315).

[0042] A surveillance camera device (10) according to an embodiment of the present invention may further include a cushioning member (330) fixed on a bottom cover (300). The cushioning member (330) may be a portion that is in direct contact with and seated on the camera housing (100) on the bottom cover (300). The cushioning member (330) may be a portion that presses the camera housing (100) by receiving an external force provided by the base (500) when the connecting cover (200) is fixed to the base (500). The cushioning member (330) may include an opening hole (333) that opens the open hole (310). Preferably, the cushioning member (330) may have an annular shape that opens the open hole (310) of the bottom cover (300).

[0043] The cushioning member (330) may be formed of a material having a predetermined elasticity. The cushioning member (330) may be formed of a rubber material, but is not limited thereto. The cushioning member (330) may be formed of a material having a predetermined elasticity and may perform the function of cushioning so that the camera housing (100) is not damaged when in contact with the camera housing (100).

[0044] The buffer member (330) may further include an extended opening hole (335) that is laterally connected to the opening hole (333) and serves as an extension path for the cable (130). The function of the extended opening hole (335) may be the same as the function of the extended opening hole (315) described above. The extended opening hole (335) may be connected in the vertical direction to the extended opening hole (315). As another example, as shown in FIG. 3, the extended opening hole (335) may be formed in the buffer member (330) and the extended opening hole (315) may not be formed in the bottom cover (300).

[0045] Referring further to FIG. 4, a surveillance camera device (10) according to an embodiment of the present invention may include a position adjustment unit (400) for detachably connecting a bottom cover (300) to a connecting cover (200). The position adjustment unit (400) may be fixed to the inner surface of the connecting cover (200). The position adjustment unit (400) may be fixed at a plurality of locations on the inner surface of the connecting cover (200), and the plurality of position adjustment units (400) may be positioned spaced apart at a predetermined interval. For example, there may be two position adjustment units (400), and the two position adjustment units (400) may be formed on the left and right sides, respectively, and may be arranged opposite each other along the left and right directions. As another example, the plurality of position adjustment units (400) may be arranged radially with respect to a virtual central axis of the connecting cover (200) and may be arranged spaced apart from each other at a predetermined interval along the circumferential direction.

[0046] The bottom cover (300) can be detachably connected to the connecting cover (200) via a position adjustment unit (400). The position adjustment unit (400) can restrict the bottom cover (300) from detaching from the connecting cover (200) unless a predetermined external force is provided while the bottom cover (300) is connected to the connecting cover (200). The position adjustment unit (400) can allow a predetermined movement while the bottom cover (300) is connected to the connecting cover (200).

[0047] More specifically, the position adjustment unit (400) may allow movement of the bottom cover (300) within a preset range while restricting the detachment of the bottom cover (300). The movement of the bottom cover (300) may mean movement of the bottom cover (300) in the up and down direction within the internal space of the connecting cover (200). This may mean that relative movement (rotation) with respect to the connecting cover (200) is possible while the camera housing (100) is restricted from detaching upward and downward by the connecting cover (200) and the bottom cover (300). Such movement of the camera housing (100) may be performed in a temporary assembly state to be described later. Such movement of the bottom cover (300) and movement (rotation) of the camera housing (100) may be constrained while the base (500), to be described later, is fixed to the connecting cover (200).

[0048] The position adjustment unit (400) may include an elastic member (410) having a predetermined elastic force. The position adjustment unit (400) may allow the bottom cover (300) to be drawn into the internal space of the connecting cover (200) by elastic deformation due to the elastic force, and may restrict the bottom cover (300) from moving out of the internal space of the connecting cover (200) by restoring force.

[0049] Preferably, the position adjustment part (400) may be a finger spring (410). The finger spring (410) may be formed by bending a single plate. The finger spring (410) may include a first plate (411) fixed to the connecting cover (200) and a second plate (413) that is bent from the first plate (411) and extends downward. One end of the second plate (413) may be a free end. The finger spring (410) may be elastically deformed by an external force provided, so that the gap between the first plate (411) and the free end of the second plate (413) may change. That is, the free end of the second plate (413) may maintain a state separated from the first plate (411) by a predetermined distance when no external force is provided, and may be elastically deformed and move adjacent to the first plate (411) when an external force is provided. The elastically deformed state of the finger spring may be referred to as the first state, and the restored state may be referred to as the second state. The bottom cover (300) may be allowed to be inserted into the internal space of the connecting cover (200) while the finger spring (410) is deformed and maintained in the first state, and may be restricted from being withdrawn from the connecting cover (200) to the outside while the finger spring (410) is maintained in the second state.

[0050] The finger spring (410) may be positioned above the protrusion (220). The free end of the second plate (413) and the end (221) of the protrusion (220) may be positioned apart by a predetermined distance along the vertical direction. The bottom cover (300) may be positioned between the free end of the second plate (413) and the end (221) of the protrusion (220), and movement in the vertical direction may be allowed within a preset range. The preset range may correspond to the distance between the free end of the second plate (413) and the end (221) of the protrusion (220).

[0051] The position adjustment unit (400) may further include at least one fixing pin (420) for restricting the rotation of the bottom cover (300). The rotation of the bottom cover (300) may refer to rotational movement relative to a virtual central axis of the connecting cover (200). The fixing pin (420) may be fixed to the inner surface of the connecting cover (200). The fixing pin (420) may be located below the elastic member (410). The fixing pin (420) may extend in the vertical direction. The upper end of the fixing pin (420) may be located adjacent to the elastic member as a free end.

[0052] Preferably, the fixing pin (420) can be fixed to the end (221) of the protrusion (220). For example, the fixing pin (420) may be formed on a support plate (425) corresponding to the shape of the end (221) of the protrusion (220), and the support plate (425) may be fixed to the end (221) of the protrusion (220) through at least one fixing means. The fixing means may be a screw, but is not limited thereto. In order to prevent mutual interference between the second plate (413) and the fixing pin (420) when the finger spring (410) is elastically deformed, the second plate (413) may include an avoidance hole (415) provided by removing a portion inward from the free end.

[0053] The bottom cover (300) may include a fixing hole (325) formed by penetrating in the vertical direction so as to be inserted into and withdrawn by a fixing pin (420). The fixing hole (325) may be open toward the side. The bottom cover (300) may be accommodated in the internal space of the connecting cover (200) by the elastic deformation of the elastic member (410), and in this process, the fixing pin (420) may be inserted into the fixing hole (325). As the fixing pin (420) is fastened to the fixing hole (325), the relative rotational movement of the bottom cover (300) with respect to the connecting cover (200) may be restricted. Restricting relative rotation may mean that the rotational movement of the bottom cover (300) is restricted while the connecting cover (200) is fixed. As the fixing pin (420) is fastened to the fixing hole (325), the movement path of the bottom cover (300) in the vertical direction can be guided in the extension direction of the fixing pin (420). For example, the bottom cover (300) may include an extension portion (320) extending outward from the outer surface, and the fixing hole (325) may be formed in the extension portion (320).

[0054] As the fixing pin (420) is fastened to the fixing hole (325), the bottom cover (300) can also move (rotate) in response to the movement (rotation) of the connecting cover (200). This means that the position of the cut portion (210) and the position of the extension area of ​​the bottom cover (300) can be aligned to be located at the front and rear, respectively. This means that when the connecting cover (200) is fastened to the base (500), even if the position of the connecting cover (200) is adjusted in response to the imaging area, the position of the cable (130) can be maintained aligned with the extension area of ​​the bottom cover (300). This means that interference between the cable (130) and the bottom cover (300) can be minimized.

[0055] Referring further to FIG. 5, the base (500) may be detachably installed on a preset installation target. The installation target to which the base (500) is fixed may include, but is not limited to, columns, beams, ceilings, side walls, etc. of other architectural structures. The base (500) may be fixed to the installation target by a screw connection method, but is not limited thereto.

[0056] The base (500) may be a part to which the connecting cover (200) is fixed. That is, the connecting cover (200) may be detachably fastened to the base (500). The base (500) and the connecting cover (200) may be fixed by at least one fixing means. The fixing means may be a screw, but is not limited thereto, and may include a mechanical fastening structure such as a snap-fit.

[0057] The base (500) may include an internal space (510) that communicates with the internal space of the connecting cover (200). The base (500) may include at least one extraction hole (550) formed on the side to open the internal space (510) to the outside. The internal space (510) and the extraction hole (550) of the base (500) may function as an extension path for the cable (130). Since the extraction hole (550) is formed on the side of the base (500), the cable (130) may be easily extracted during the process of fixing the connecting cover (200) to the base (500) after fixing the base (500) to the object to be installed. If necessary, the base (500) may further include a door (560) for opening and closing the extraction hole (550). The door (560) can be used to close the withdrawal hole (550) so that the unused withdrawal hole (550) is not recognized from the outside, and can be used to block the entry of foreign matter through the unused withdrawal hole (550). The door (560) may be provided to cover the withdrawal hole (550) in a sliding manner, but is not limited thereto.

[0058] The base (500) may include a first body (520) and a second body (530) that extends from the first body (520) and is located below the first body (520).
