Description

[Technical field]

[0001] The present disclosure relates to surveillance cameras. [Background technology]

[0002] A vertical pole suspension device for suspending security cameras or lighting equipment from the ceiling in pachinko parlors, banks, etc. is known (see Patent Document 1). This vertical pole suspension device suspends a vertical pole from the ceiling by penetrating the ceiling material. The suspension device uses a number of ceiling material mounting members attached at regular intervals on the back side of the ceiling material to bridge a horizontal suspension rod between a pair of adjacent and opposing ceiling mounting members, and engages and nuts U-bolts with short pole insertion tubes in mounting holes provided at appropriate intervals in the longitudinal direction of the horizontal suspension rod. In this way, the suspension device is configured to attach the short pole insertion tube to the horizontal suspension rod, insert the vertical pole into the short pole insertion tube by penetrating the ceiling material, and screw a set bolt into the side of the short tube to press and fix the vertical pole to the short pole insertion tube at its tip. The suspension device has a surveillance camera or the like attached to the lower end of a vertical pole, and electric wires and cables are routed through the inside of the vertical pole to the ceiling.

[0003] [Patent Document 1] Publication number 7-53377 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in conventional vertical pole suspension devices, wires or cables are inserted into the vertical pole from the top or bottom end, and then taken out from the top opening of the vertical pole above the ceiling. In other words, the cable is passed through the inside of the pole to connect to the camera, but if the cable on the ceiling side comes off, the cable may get stuck inside the pole due to gravity or fall off, which can make reconnection a hassle. In addition, taping the cable to prevent it from getting stuck inside the pole or falling off, and removing the taping after the wiring work is completed is extremely troublesome, difficult to work with, and dangerous in the narrow space above the ceiling.

[0005] The present disclosure has been devised in consideration of the above-mentioned conventional circumstances, and aims to provide a surveillance camera with a pole stand in which the cable does not get caught in the pole and is prevented from falling off. [Means for solving the problem]

[0006] The present disclosure provides a surveillance camera having a camera body, a cable connected to the camera body, and a pole with a hollow cross-section that accommodates the cable, the camera body being provided on one end of the pole, the cable having connection portions at both ends, and the outer diameter of the connection portions being larger than the inner diameter of the cross-section of the pole. Effect of the Invention

[0007] According to the present disclosure, in a surveillance camera having a pole stand, the cable does not get caught in the pole, preventing it from falling off. [Brief description of the drawings]

[0009] Hereinafter, with reference to the drawings as appropriate, an embodiment specifically disclosing a surveillance camera according to the present disclosure will be described in detail. However, more detailed explanation than necessary may be omitted. For example, detailed explanation of already well-known matters or duplicate explanation of substantially the same configuration may be omitted. This is to avoid the following explanation becoming unnecessarily redundant and to facilitate understanding by those skilled in the art. Note that the attached drawings and the following explanation are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0010] Fig. 1 is an external perspective view of a surveillance camera 11 according to embodiment 1. The surveillance camera 11 has a camera body 13, a support part 15, a pole 17, a cable 19, a connection part (e.g., male LAN connectors 21a, 21b), a coupling part 23, and a rotating part 25 (see Fig. 7 or 10).

[0011] Surveillance camera 11 has compact camera body 13 attached to the tip of long, thin pole 17, and is fixed to the ceiling surface by support part 15 fixed to the base end opposite the tip of pole 17, allowing it to hang down from the ceiling surface and capture images mainly in depression angles, including straight down. However, by rotating rotating part 25 (see Fig. 7 or Fig. 10), it is also possible to capture images in the horizontal or elevation directions.

[0012] 2 is a front view of the vicinity of the support part. The support part 15 fixes the pole 17 so that it cannot rotate relative to the pole 17 and restricts movement along the axis of the pole 17. The support part 15 is made of a lightweight and strong metal (e.g., aluminum alloy, etc.) or a synthetic resin material (ABS, etc.) in order to support the load of the surveillance camera 11 on the ceiling.

[0013] In this specification, directions are based on the directions of the arrows on the X-axis, Y-axis, and Z-axis shown in Fig. 2. Here, the X direction indicates the rightward direction, the Y direction indicates the upward direction, and the Z direction indicates the forward direction. Thus, although not shown in the figures, the -X direction is the leftward direction, the -Y direction is the downward direction, and the -Z direction is the backward direction. Also, the circle surrounding the point at the intersection of the orthogonal axes indicates the direction of the arrows as seen from the front.

[0014] The support part 15 is fixed to the ceiling surface by a pair of ceiling fixing screws 27 that point toward the ceiling from below. The support part 15 consists of a right support part 29 and a left support part 31. The right support part 29 and the left support part 31 are fastened together by a pair of support part joining screws 33 (see FIG. 3) that are provided at the front and rear of the pole 17 and inserted in the left-right direction. In other words, the support part 15 that supports the pole 17 is provided at the other end (upper end) of the pole 17.

[0015] The pole 17 is formed by fixing together a pair of concave curved plates, which are divided into two by a plane parallel to an axis parallel to the Y-axis. That is, the pole 17 is made up of a right concave curved plate 35 and a left concave curved plate 37. The right concave curved plate 35 and the left concave curved plate 37 are fixed together by being sandwiched between the right support part 29 and the left support part 31 as the right support part 29 and the left support part 31 are fastened together from the left and right directions by support part joining screws 33. The integrated right support part 29 and left support part 31 form a tube with a circular cross section (hollow cross section). The right support part 29 and the left support part 31 are made of, for example, stainless steel.

[0016] A cable 19 is inserted into the inside of the pole 17. The pole 17 accommodates the cable 19 inside its hollow cross section. A male LAN connector 21a, which is a connection part, is attached to the end of the cable 19 drawn out from the lower end of the pole 17. A male LAN connector 21b, which is a connection part, is attached to the end of the cable 19 drawn out from the upper end of the pole 17. The cable 19 has male LAN connectors 21a, 21b at both ends. The lower end of the cable 19 is electrically connected to the camera body 13 via the male LAN connector 21a. The outer shape (outer diameter) of the connection part (male LAN connector 21) is larger than the inner diameter of the cross section of the pole 17. The outer diameter of the connection part has the same length as the diameter of a circle circumscribing the outer shape of the male LAN connector 21.

[0017] The male LAN connectors 21a, 21b have a locking piece 39, and the locking piece 39 can be elastically deformed to lock or unlock the mating connector. In the example of Fig. 2, the locking piece 39 faces forward (in other words, the front side), but the cable 19 can be rotated inside the pole 17 to face in any direction.

[0018] FIG. 3 is a perspective view of the vicinity of the support part as seen from the diagonally rear lower side. The pair of support part connecting screws 33, which are provided in front and behind the pole 17, are fastened in the opposite directions. That is, the right support part connecting screw 33 is inserted from the left support part 31 and screwed into the right support part 29. The left support part connecting screw 33 is inserted from the right support part 29 and screwed into the left support part 31. The support part 15 is approximately rhombus with four corners chamfered in a plan view. The two diagonals of the approximately rhombus are different lengths, but intersect at right angles at their respective midpoints. The support part 15 is divided into the right support part 29 and the left support part 31 at the position of the shorter diagonal, and the pair of divided right concave curved plates 35 and left concave curved plates 37 are sandwiched from the concave curved plate sides and fixed together.

[0019] The pair of divided right concave curved plates 35 and left concave curved plates 37 are fixed together to form the pole 17. The upper end of the pole 17 is fixed by the support part 15, and the lower end is fixed by the connecting part 23 described below. The long pole 17 is appropriately fixed between its upper and lower ends by multiple C-shaped clamps 41 shown in Fig. 1.

[0020] Fig. 4 is a view taken along the line AA in Fig. 2. The line AA is to the right of the axis of the pole 17 in the front view shown in Fig. 2. Therefore, Fig. 4 shows cross sections of the right support part 29 and the right concave curved plate 35.

[0021] A cable lead-in hole (not shown) coaxial with the pole 17 is drilled in the ceiling at the position where the support part 15 is fixed. The cable lead-in hole has a size that allows the male LAN connector 21b to be inserted therethrough, and is also large enough to be entirely covered by the support part 15. This allows the cable 19 passed through the pole 17 to be concealed and wired above the ceiling, covering the cable lead-in hole.

[0022] The right support part 29 and the left support part 31 are provided with a support part through hole 43 into which the support part connecting screw 33 is inserted on one side sandwiching the pole 17, and a support part fixing hole 45 into which the support part connecting screw 33 is screwed on the other side sandwiching the pole 17. In the right support part 29, the support part through hole 43 is drilled on the right side sandwiching the pole 17 in view of arrow B in Fig. 3, and the support part fixing hole 45 is drilled on the left side sandwiching the pole 17. In the left support part 31, the support part through hole 43 is drilled on the right side sandwiching the pole 17 in view of arrow D in Fig. 3, and the support part fixing hole 45 is drilled on the left side sandwiching the pole 17.

[0023] Fig. 5 is a side view of the support part 15 as viewed from direction B in Fig. 3. In the right support part 29, the support part fixing hole 45 appears on the front side across the pole 17, and the support part connecting screw 33 inserted through the support part through hole 43 appears on the rear side across the pole 17. In Fig. 5, the connection part shows the side surface on the short diagonal side of the approximate diamond shape.

[0024] Fig. 6 is a view seen from the CC arrow in Fig. 5. The support part 15 has a second locking part 47 for locking with the pole 17 on the surface facing the pole 17. The first locking part will be described later for convenience of explanation. The second locking part 47 is provided on each of the right support part 29 and the left support part 31. The second locking part 47 is composed of, for example, a locking protrusion 49 and a locking hole 51. The support part 15 is formed with a pole upper end through hole 53 through which the upper end of the pole 17 passes.

[0025] The inner peripheral surface of the pole upper end through hole 53 becomes the above-mentioned opposing surface. The locking protrusions 49 protrude radially inward from the inner peripheral surface of the pole upper end through hole 53 and are provided intermittently in the inner peripheral direction. The locking holes 51 are formed radially inward from the outer periphery of the pole 17 and are provided intermittently in the circumferential direction of the pole 17. The locking holes 51 are arranged according to the locking protrusions 49 so that the locking protrusions 49 protruding from the inner peripheral surface of the support part 15 can be fitted into the locking holes 51. In addition, the support part 15 has ceiling fixing through holes 55 drilled in each of the right support part 29 and the left support part 31 for inserting the ceiling fixing screws 27 for fixing the support part 15 to the ceiling.

[0026] FIG. 7 is a side view of the surveillance camera 11 as viewed from the direction D in FIG. 3. The surveillance camera 11 has a connecting portion 23 that connects the pole 17 and the camera body 13. The connecting portion 23 has a first extending portion 57 and a second extending portion 59. One end of the first extending portion 57 is fixed to the pole 17 and extends in a direction intersecting the pole 17. The second extending portion 59 extends from the other end of the first extending portion 57 and is connected to the camera body 13. That is, the connecting portion 23 is formed in a substantially L-shape by the first extending portion 57 that intersects the pole 17 and the second extending portion 59 that extends in the extension direction of the pole 17. The substantially L-shape here includes an L-shape, and the same applies below. The connecting portion 23 is made of a lightweight and strong metal (e.g., aluminum alloy, etc.) or a synthetic resin material (ABS, etc.) in order to support the load of the camera body 13 on the pole 17.

[0027] In the substantially L-shaped connecting portion 23, a substantially L-shaped right connecting plate 61 (see FIG. 8) and a substantially L-shaped left connecting plate 63 (see FIG. 8) are fixed together with the lower end of the pole 17 in between. A connecting portion through hole (not shown) into which a connecting portion fixing screw 65 is inserted is formed in each of the first extending portion 57 and the second extending portion 59 of the left connecting plate 63. A connecting portion fixing hole 67 (see FIG. 10) into which the connecting portion fixing screw 65 is screwed is formed in each of the first extending portion 57 and the second extending portion 59 of the right connecting plate 61. The inside of the connecting portion fixing hole 67 is a female screw. In the connecting portion 23 in which the first extending portion 57 is fixed to the lower end of the pole 17, the second extending portion 59 is connected to the camera body 13. In other words, the pole 17 and the camera body 13 are connected by the connecting portion 23.

[0028] Fig. 8 is a view seen from the arrow EE in Fig. 7. Camera body 13 connected to the lower end of pole 17 is supported by a substantially L-shaped connecting part 23, and hangs down with its axis offset rearward from the long diagonal of the substantially diamond-shaped connecting part. Camera body 13 accommodates camera unit 71 (see Fig. 11) inside camera housing 69 formed into a cylindrical shape. A lens holder 75 for fixing lens 73 is attached to the tip surface (lower end surface) of camera housing 69.

[0029] Fig. 9 is a view seen from the arrow FF in Fig. 7. When viewed from the front in Fig. 9, the camera body 13 fixed to the lower end of the pole 17 via the connecting portion 23 has the cable 19 and the male LAN connector 21a exposed between the first extending portion 57 and the camera body 13. That is, the connecting portion 23 is provided with an exposure gap K in which the cable 19 and the male LAN connector 21a are exposed. When the camera body 13 faces directly downward, the exposed cable 19 is connected straight to the camera body 13 along the second extending portion 59 via the male LAN connector 21a.

[0030] The cable 19 in this exposure gap K is bent and pulled out from the lower end of the pole 17 or pushed into the ceiling from the lower end of the pole 17 by rotating the camera body 13 at the rotating part 25 that connects the second extension part 59 and the camera body 13. That is, the cable 19 has a part exposed from the upper end or the lower end of the pole 17. The cable 19 is also movable in the vertical direction relative to the pole 17. At this time, the exposure gap K is provided in the surveillance camera 11, so that the cable 19 and the connecting part 23 are less likely to interfere with each other. Also, if the male LAN connector 21a is disconnected from the camera body 13, it is easy to reconnect it to the camera body 13 because the male LAN connector 21a is exposed.

[0031] Fig. 10 is a view taken along the arrow GG in the vicinity of the connecting portion shown in Fig. 9. The line GG is located to the right of the axis of the pole 17 in the front view shown in Fig. 9. Therefore, a cross section of the right connecting plate 61 is shown in Fig. 10.

[0032] The surface of the first extension portion 57 facing the pole 17 has a first locking portion 77 for the pole 17. The first locking portion 77 is provided on each of the right connecting plate 61 and the left connecting plate 63. The first locking portion 77 is composed of, for example, a locking protrusion 79 and a locking groove 81. The locking protrusion 79 protrudes radially outward from the outer periphery of the pole 17 and is provided continuously or discontinuously in the circumferential direction of the pole 17.

[0033] The first extending portion 57 is formed with a pole lower end through hole 83 through which the lower end of the pole 17 passes. The inner peripheral surface of the pole lower end through hole 83 becomes the above-mentioned opposing surface. The locking groove 81 is formed in this pole lower end through hole 83. The locking groove 81 is provided continuously in the inner peripheral direction by recessing the pole lower end through hole 83 radially outward so that the locking protrusion 79 can fit therein. A lightening portion 85 for reducing weight may be provided on the mating surface between the right connecting plate 61 and the left concave curved plate 37. The surveillance camera 11 has a rotating portion 25 between the camera body 13 and the second extending portion 59.

[0034] Fig. 11 is a view taken along the arrows GG near the camera body shown in Fig. 9. The rotation axis of the rotating part 25 is perpendicular to the longitudinal direction of the first extending part 57 and perpendicular to the longitudinal direction of the second extending part 59. The rotating part 25 is made up of a connecting and fixed shaft 87 that penetrates the second extending part 59 in the direction along the rotation axis, and a pair of bearing plates 89 that are fixed to the base end surface of the camera housing 69 and support both ends of the connecting and fixed shaft 87.

[0035] The connecting unit 23 connects the lower end of the pole 17 and the camera body 13 to be rotatable around the central axis of rotation of the connecting and fixed shaft 87 by a rotating unit 25 consisting of the connecting and fixed shaft 87 and the bearing plate 89. The connecting and fixed shaft 87 has, for example, a male threaded portion that screws into one of the bearing plates 89. After the camera body 13 is manually rotated by the user in a desired imaging direction by this rotating unit 25, the connecting and fixed shaft 87 is fastened to the female threaded portion of one of the bearing plates 89 and fixed at a predetermined angle.

[0036] A female LAN connector 91 electrically connected to the internal camera unit 71 is provided on the base end surface of the camera housing 69. A male LAN connector 21a attached to the tip of the cable 19 drawn out from the lower end of the pole 17 is coupled to this female LAN connector 91, completing the electrical connection with the camera unit 71.

[0037] Next, the operation of the above-mentioned configuration will be described.

[0038] The surveillance camera 11 in embodiment 1 has a camera body 13, a cable 19 connected to the camera body 13, and a pole 17 with a hollow cross-section that accommodates the cable 19, with the camera body 13 provided on one end of the pole 17, and the cable 19 having connection portions at both ends, with the outer diameter of the connection portions being larger than the inner diameter of the cross-section of the pole 17.

[0039] In surveillance camera 11 according to embodiment 1, cable 19 is connected to camera body 13. Camera body 13 is attached to one end of pole 17. Here, one end of pole 17 refers to the lower end of pole 17. Camera body 13 is attached to the lower end of pole 17, and the upper end of pole 17 is fixed to, for example, a ceiling, so that camera body 13 is supported in a state of being suspended from the ceiling by pole 17. In other words, in surveillance camera 11, pole 17 serves as a support pipe material that supports the weight of camera body 13 on the ceiling.

[0040] Pole 17 is hollow in cross section and houses cable 19 inside. This allows surveillance camera 11 to have cable 19 from camera body 13 attached to the bottom end passed through pole 17 and pulled into the ceiling without being exposed to the outside. In other words, surveillance camera 11 has cable 19 from camera body 13 concealed and wired up to the ceiling using pole 17, which is a supporting pipe material.

[0041] Cable 19 has connection parts attached to both ends pulled out from pole 17. The connection part attached to the end of cable 19 pulled out from the lower end of pole 17 is connected (connector connected) to camera body 13. On the other hand, the connection part attached to the end of cable 19 pulled out from the upper end of pole 17 is connected (connector connected) to an electric wire wired above the ceiling.

[0042] The outer diameter of the connection part is set to be larger than the inner diameter of the cross section of the pole 17. Therefore, when the pole 17 is attached vertically to the ceiling and the cable 19 passed through the pole 17 falls due to gravity, the connection part gets caught at the upper end of the pole 17, and the cable 19 does not get stuck inside the pole or fall off.

[0043] As a result, the wiring connection work can be completed in a short time without having to reconnect the cable 19 through the pole 17. In addition, there is no need to tap the cable 19 inside the pole or to prevent it from falling off, and there is no need to remove the taping, so wiring work can be completed smoothly and safely at high altitudes.

[0044] In addition, the pole 17 has a small inner diameter (i.e., is thin) that allows the cable 19 to pass through, improving the design. For example, when a compact camera body 13 is attached, the balance of the entire surveillance camera becomes poor, and this can be prevented from deteriorating the design (the superiority of the design is enhanced).

[0045] Moreover, the pole 17 has a structure in which a pair of concave curved plates divided into two on a plane parallel to an axis parallel to the Y-axis are fixed together. In a conventional pole structure that is not divided, if the inner diameter of the pole is made smaller than the connection part, after the cable is inserted into the pole, post-processing is required to attach the connection parts above and below the cable. In contrast, in the pole structure of this embodiment, the pole 17 is divided into two, so the cable 19 to which the connection part is attached can be attached by sandwiching it between the two poles 17. Therefore, assembly can be performed without post-processing to attach the connection part to the cable 19. This structure makes it easier to assemble the pole 17, enhances the superiority of the design, and at the same time, prevents the connection part from falling off.

[0046] Therefore, in surveillance camera 11 according to the first embodiment, in surveillance camera 11 having a pole stand, cable 19 does not get inside the pole, and falling off can be prevented.

[0047] In the surveillance camera 11, the pole 17 has a pair of concave curved plates that are divided into two parts by a plane parallel to the axis and are fixed integrally thereto.

[0048] In this surveillance camera 11, the pole 17 is made of a pair of concave curved plates divided into two. The pair of concave curved plates are fixed together by the support part 15 at the upper end and the connecting part 23 at the lower end. As a result, the pole 17 can be covered with the cable 19 with the connecting parts already attached to both ends, allowing the cable 19 to pass through. In other words, there is no need for a work procedure that requires attaching the connecting parts. For example, by wiring the electric wire connected to the female LAN connector 91 (modular socket, etc.) that is the connecting partner inside the ceiling in advance, the wiring connection work can be easily completed by simply connecting the male LAN connectors 21a, 21b (modular plug, etc.), which are the connecting parts of the cable ends drawn out from the upper end of the pole 17, without the need to attach the connector.

[0049] Also, there is no need for the time-consuming task of inserting the weak, thin, and flexible cable 19 into one end of the long pole 17 and pulling it out from the other end. Furthermore, even if cable 19 needs to be replaced during maintenance after the surveillance camera 11 has started operating, there is no need for the complicated task of connecting cable 19 to a connection part.

[0050] Moreover, the surveillance camera 11 further includes a connection part 23 that connects the pole 17 and the camera body 13 to each other.

[0051] In this surveillance camera 11, a connecting portion 23 for connecting the camera body 13 is provided at the lower end of the pole 17. As a result, the camera body 13 is integrally connected to the pole 17, and the upper end of the pole 17 is supported by the ceiling, so that the camera body 13 can be attached without hanging down from the ceiling and falling. The camera body 13 is supported by the connecting portion 23 at the lower end of the pole 17 with a predetermined strength. That is, compared to the case where the camera body 13 is supported by hanging it from the ceiling only via the cable 19, the camera body 13 can be fixed with high strength and in a predetermined direction. In addition, the load of the camera body 13 is not applied to the cable 19, so there is no risk of the cable breaking due to tension acting on the core wire.

[0052] In addition, in the surveillance camera 11, the connecting portion 23 has a first extension portion 57 having one end fixed to the pole 17 and extending in a direction intersecting the pole 17, and a second extension portion 59 extending from the other end of the first extension portion 57 and connected to the camera body 13.

[0053] In this surveillance camera 11, connecting portion 23 has one end fixed to pole 17 and has a first extending portion 57 extending in a direction intersecting pole 17. First extending portion 57 extends from the other end and has a second extending portion 59 connected to camera body 13. Second extending portion 59 extends in the extension direction of pole 17. In other words, connecting portion 23 is formed into a substantially L-shape by first extending portion 57 intersecting pole 17 and second extending portion 59 extending in the extension direction of pole 17.

[0054] A cable 19 that is passed through the inside of the pole 17 is pulled out from the pole 17 fixed to the first extending portion 57. The pulled out cable 19 extends along the second extending portion 59 and is connected to the camera body 13 that is connected to the lower end of the second extending portion 59. In other words, the cable 19 is exposed between the lower end of the pole 17 and the camera body 13. The provision of this exposed gap K makes the cable 19 bendable, facilitating the connection work (connector connection) to the camera body 13.

[0055] In the surveillance camera 11 , the surface of the first extending portion 57 facing the pole 17 has a first locking portion 77 for engaging with the pole 17 .

[0056] In this surveillance camera 11, a first locking portion 77 is provided on the surface of the first extension portion 57 facing the pole 17, for locking the lower end of the pole 17 and the first extension portion 57. The first locking portion 77 is composed of a locking protrusion 79 and a locking groove 81, for example.

[0057] The locking projections 79 protrude radially outward from the outer periphery of the pole 17, and are provided continuously or intermittently in the circumferential direction of the pole 17. The locking grooves 81 are formed in the pole lower end through-holes 83 of the first extending portions 57. The locking grooves 81 are provided continuously in the inner circumferential direction by recessing the inner circumferential surface radially outward so that the locking projections 79 can fit into them.

[0058] As a result, the locking groove 81 of the connecting part 23 fits into the locking protrusion 79 of the pole 17, restricting axial movement relative to the pole 17 while allowing rotation around the pole, thereby supporting the camera body 13 on the lower end of the pole 17.

[0059] In addition, the surveillance camera 11 has a rotating part 25 between the camera body 13 and the second extending part 59 .

[0060] In this surveillance camera 11, as described above, the connecting portion 23 has a first extending portion 57 that extends in a direction intersecting the pole 17 and has one end fixed to the pole 17. The connecting portion 23 is formed into a substantially L-shape by the first extending portion 57 and a second extending portion 59 that bends at a right angle from the other end of the first extending portion 57, extends in the extension direction of the pole 17, and is connected to the camera body 13. The second extending portion 59 has a rotating portion 25 between it and the camera body 13. The rotating portion 25 has a rotation center axis that is perpendicular to the longitudinal direction of the first extending portion 57 and perpendicular to the longitudinal direction of the second extending portion 59.

[0061] The rotating part 25 is made up of a connecting and fixed shaft 87 that penetrates the second extending part 59 in a direction along the central axis of rotation, and a pair of bearing plates 89 that are fixed to the camera housing 69 and support both ends of the connecting and fixed shaft 87. The connecting part 23 connects the lower end of the pole 17 and the camera housing 69 to be rotatable around the central axis of rotation of the connecting and fixed shaft 87 by the rotating part 25 made up of the connecting and fixed shaft 87 and the bearing plates 89.

[0062] Pole 17 fixed to first extending portion 57 of connecting portion 23 has a lower end that penetrates first extending portion 57 and opens at its terminal end. Cable 19 is pulled out from this opening. Pulled out cable 19 is connected to the base end surface of camera housing 69, which is connected at the lower end of second extending portion 59 via rotating portion 25.

[0063] A female LAN connector 91 electrically connected to the internal camera unit 71 is provided on the base end surface of the camera housing 69. A male LAN connector 21a attached to the tip of the cable 19 drawn out from the lower end of the pole 17 is coupled to this female LAN connector 91 to complete the electrical connection.

[0064] In the surveillance camera 11, the cable 19 is exposed between the first extending portion 57 and the base end surface of the camera housing 69. When the connecting portion 23 of the camera housing 69 is rotated by the rotating portion 25, the female LAN connector 91 provided on the base end surface of the camera housing 69 moves on an arc of a circle centered on the connecting fixed shaft 87.

[0065] Cable 19, which is pulled out from the opening of pole 17 penetrating first extending portion 57, is bent or pulled with the movement of female LAN connector 91, and maintains the connected state. In other words, connecting portion 23 rotatably connects camera body 13 while maintaining the connected state of cable 19. When female LAN connector 91 moves in a direction away from the bottom end of pole 17, cable 19 is pulled out from inside the pole. The extra length of cable 19 pulled out is secured in the ceiling as slack.

[0066] In addition, in the surveillance camera 11, a support part 15 for supporting the pole 17 is provided at the other end of the pole 17.

[0067] In this surveillance camera 11, a support part 15 that supports the pole 17 is provided at the other end of the pole 17. Here, the other end of the pole 17 is the upper end of the pole 17. The upper end of the pole 17 is supported by the support part 15, for example, on a ceiling. In a plan view, the support part 15 is substantially rhombus with four corners chamfered. The two diagonals of the substantially rhombus have different lengths but intersect at right angles at their respective midpoints. The support part 15 is divided into two at the position of the shorter diagonal, and the pair of divided concave curved plates are sandwiched from the respective concave curved plate sides and fixed together.

[0068] The two split halves of the support part 15 are fastened together to integrally fix the pole 17. The surveillance camera 11 has a diamond-shaped support part 15 parallel to the ceiling surface fixed to the upper end of the pole 17. By fixing this support part 15 to the ceiling surface, the surveillance camera 11 is supported with the fixed pole 17 hanging down from the ceiling. In other words, the support part 15 has two functions: to fix the pair of split concave curved plates together, and to fix the upper end of the pole 17 fixed together to the ceiling surface.

[0069] In addition, in the surveillance camera 11 , the surface of the support part 15 facing the pole 17 has a second locking part 47 for engaging with the pole 17 .

[0070] In this surveillance camera 11, a second locking portion 47 that locks the upper end of the pole 17 to the support portion 15 is provided on the surface of the support portion 15 facing the pole 17. The second locking portion 47 is composed of, for example, a locking protrusion 49 and a locking hole 51. A pole upper end through hole 53 through which the upper end of the pole 17 passes is formed in the support portion 15. The inner peripheral surface of the pole upper end through hole 53 becomes the above-mentioned facing surface.

[0071] The locking protrusions 49 protrude radially inward from the inner peripheral surface of the pole upper end through hole 53 and are provided intermittently in the inward peripheral direction. The locking holes 51 are formed radially inward from the outer periphery of the pole 17 and are provided intermittently in the circumferential direction of the pole 17.

[0072] The locking holes 51 are arranged in accordance with the locking protrusions 49 so that the locking protrusions 49 protruding from the inner peripheral surface of the support part 15 can fit into the locking holes 51. As a result, the upper end of the pole 17 is supported on the ceiling surface by restricting the movement in the axial direction and the rotation around the pole as the locking protrusions 49 fit into the locking holes 51 of the pole 17.

[0073] In addition, in the surveillance camera 11 , a gap is provided between one end of the pole 17 and the camera body 13 .

[0074] In this surveillance camera 11, a gap (see exposed gap K in FIG. 9) is provided between one end of the pole 17 and the camera body 13. Therefore, the cable 19 has a portion exposed from the upper end or the lower end of the pole 17, and is movable in the vertical direction relative to the pole 17. At this time, by providing a gap between the one end of the pole 17 and the camera body 13, interference between the cable 19 and the connecting portion 23 is reduced, and connection between the camera body 13 and the connecting portion (for example, male LAN connector 21a) is facilitated.

[0075] In the surveillance camera 11, the cable 19 and the connection part are exposed from one end of the pole 17. The camera body 13 and the connection part are connected.

[0076] In this surveillance camera 11, the cable 19 and the connection part (e.g., male LAN connector 21a) are exposed from one end of the pole 17, and the camera body 13 is connected to the connection part (e.g., male LAN connector 21a). Therefore, if the connection between the male LAN connector 21a and the camera body 13 becomes disconnected, the male LAN connector 21a can be easily reconnected to the camera body 13 because the male LAN connector 21a is exposed to the outside.

[0077] Furthermore, in surveillance camera 11, cable 19 is movable inside pole 17. As a result, in the case where surveillance camera 11 is suspended from the ceiling, even if camera body 13 rotates, cable 19 can move inside pole 17 and follow the rotation of camera body 13, so that the suspension support of surveillance camera 11 is unlikely to collapse. In addition, the connection between the camera body 13 and the connection portion is unlikely to come off when the camera body 13 is rotated.
