Description

[Technical Field]

[0001] The present invention relates to an imaging device and a mounting method thereof. [Background technology]

[0002] Conventionally, imaging devices that are attached to a wall and monitor the surroundings have been known (Patent Document 1). The imaging device described in Patent Document 1 is capable of monitoring the surroundings by fixing the camera body to a base that is fixed to the wall. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 7007315 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the imaging device of Patent Document 1 requires a connection operation to electrically connect the cable extending from the base to the camera body before the camera body is fixed to the base. This connection operation is performed when the camera body is not fixed, so the operator must hold the camera body with one hand and work with the other, or the operation must be done by multiple people. As a result, the connection operation becomes complicated.

[0005] The present invention has been made in consideration of the above circumstances, and its object is to provide an imaging device that allows easy connection work for electrically connecting a bracket to a camera body. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems, the imaging device of the present invention includes a bracket having a mounting surface to be attached to a wall and a first opposing surface opposite the mounting surface, an imaging unit that images the surroundings, and a camera body having a second opposing surface located at a position outside the imaging range of the imaging unit, wherein the camera body is capable of changing its position between an imaging position in which the first opposing surface and the second opposing surface are fixed to the bracket facing each other and imaging by the imaging unit is possible, and a ready position in which the camera body is temporarily fixed to the bracket with the first opposing surface and the second opposing surface exposed, and the camera body in the ready position is temporarily fixed to the bracket by a wire connecting the first opposing surface and the second opposing surface, and a locking member attached to the first opposing surface and locking an outer peripheral wall surrounding the second opposing surface so as to restrict rotation of the camera body around a first axis that is parallel to and horizontal with the wall. [Effects of the Invention]

[0007] According to the present invention, it is possible to obtain an imaging device that allows easy electrical connection between the bracket and the camera body. Note that problems, configurations, and effects other than those described above will become clear from the description of the following embodiments. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] An embodiment of the invention will be described below with reference to the drawings. This embodiment realizes a highly versatile surveillance camera 1, which contributes to "9. Build resilient infrastructure, promote inclusive and sustainable industrialization, foster innovation and invigorate infrastructure" of the Sustainable Development Goals (SDGs) advocated by the United Nations.

[0010] [Overall configuration of surveillance camera 1] FIG. 1 is a perspective view of the surveillance camera 1 when the camera body 3 is in an imaging position. FIG. 2 is an exploded perspective view of the surveillance camera 1. FIG. 3 is a perspective view of the surveillance camera 1 when the camera body 3 is in a ready position. FIG. 4 is a cross-sectional view of the bracket 2 and the base part 4 perpendicular to the X direction (cross-sectional view taken along IV-IV in FIG. 3). The surveillance camera 1 is an imaging device that is installed on a wall W to monitor its surroundings. More specifically, the surveillance camera 1 captures images of surrounding subjects and outputs image signals (e.g., still image signals, moving image signals). As shown in FIG. 1, the surveillance camera 1 mainly comprises the bracket 2 and the camera body 3.

[0011] The wall W stands upright, generally vertically. However, the wall W may be inclined relative to the vertical direction. The surface of the wall W is generally flat. Hereinafter, among the directions parallel to the wall W, the horizontal direction is defined as the "X direction," the vertical direction is defined as the "Y direction," and the direction perpendicular to the surface of the wall W is defined as the "Z direction." In other words, the X direction, Y direction, and Z direction are directions that are perpendicular to one another.

[0012] The bracket 2 is attached to the wall W and is a member that supports the camera body 3. The bracket 2 has a generally circular disk-shaped outer shape. Of both end faces of the circular disk-shaped bracket 2, the face that is attached to the wall W is the attachment face 21, and the face opposite the attachment face 21 is the first opposing face 22. Note that each of the attachment face 21 and the first opposing face 22 is not limited to being a single face, but may be composed of multiple faces (i.e., having projections and recesses). The same applies to other faces (e.g., the second opposing face 41, the outer face 49 of the outer peripheral wall 42, and the surface 113 of the main wall 111) described below.

[0013] The mounting surface 21 is a surface that is attached to the wall W. The first opposing surface 22 is a surface that faces a second opposing surface 41, which will be described later, when the camera body 3 is in the imaging posture shown in FIG. 1. The first opposing surface 22 is a surface that is exposed to the outside when the camera body 3 is in the standby posture shown in FIG. 3. The first opposing surface 22 is a surface to which a locking member 10, which will be described later, is detachably attached. Furthermore, the first opposing surface 22 is provided with a locking portion 23 to which the other end of a wire 8, which will be described later, is detachably locked.

[0014] Furthermore, the bracket 2 has an outer peripheral wall 24. The outer peripheral wall 24 is continuous in the circumferential direction so as to surround the mounting surface 21 and the first opposing surface 22. In addition, the outer peripheral wall 24 protrudes in the Z direction in a direction away from the mounting surface 21 beyond the first opposing surface 22. Furthermore, the outer surface of the outer peripheral wall 24 is the surface that is exposed to the outside when the camera body 33 is in the imaging posture and the preparation posture.

[0015] The locking member 10 is a member that locks the camera body 3 in the ready position to the bracket 2. The locking member 10 is attached to the first opposing surface 22. A portion of the locking member 10 (more specifically, the portion on the lower surface 117 side of the slit 116) is located outside the outer peripheral wall 24 of the bracket 2. As shown in FIG. 2, the locking member 10 is located at the lower end of the bracket 2 attached to the wall W. The locking member 10 is detachably attached to the bracket 2. There are no particular limitations on the specific method of attaching the locking member 10 to the attachment surface 21, but it can be secured, for example, by bolts. Details of the locking member 10 will be described later with reference to FIGS. 6 to 10.

[0016] A space is formed inside the bracket 2 through which the cable 25 passes. The bracket 2 also allows the cable 25 to extend. More specifically, the bracket 2 allows the cable 25, which is routed inside or on the surface of the wall W, to extend from the first opposing surface 22. Note that the illustration of the cable 25 is omitted in FIG. 3. As another example, a control board may be housed inside the bracket 2. The cable 25, one end of which is connected to the control board, may extend from the first opposing surface 22. The specific role of the cable 25 is not particularly limited, but may be, for example, a power cable or a communication cable (LAN cable).

[0017] The camera body 3 is fixed to the bracket 2 and captures images of the surroundings. The camera body 3 is configured to be detachable from the bracket 2. The camera body 3 mainly includes a base 4, an arm 5, an imaging unit (imaging section) 6, and a shade 7.

[0018] The base portion 4 is a portion fixed to the bracket 2. The base portion 4 has a generally disk-shaped outer shape. One end face of the disk-shaped base portion 4 forms a second opposing surface 41. An arm 5 extends from the other end face of the disk-shaped base portion 4. Furthermore, the outer periphery of the disk-shaped base portion 4 forms an outer periphery wall 42.

[0019] The second opposing surface 41 is a surface provided at a position outside the imaging range of the imaging unit 6. More specifically, the second opposing surface 41 is the surface of the disk-shaped base portion 4 opposite the surface from which the arm 5 extends. The second opposing surface 41 is the surface that faces the first opposing surface 22 when the camera body 3 is in the imaging posture. The second opposing surface 41 is also the surface that is exposed to the outside when the camera body 3 is in the ready posture. The camera body 3 is provided with a cable 43, one end of which is connected to the imaging unit 6 and the other end of which extends from the second opposing surface 41.

[0020] Furthermore, the second opposing surface 41 is provided with an attachment portion 44 to which one end of the wire 8 is attached. As shown in FIG. 4 , the attachment portion 44 is provided at a position closer to the bracket 2 (in other words, a notch described below) than the center of gravity G of the camera body 3 when the camera body 3 is in the ready position. The center of gravity G is located, for example, at the center of the disk-shaped base portion 4. The wire 8 is a flexible, long, string-like member. The wire 8 connects the first opposing surface 22 and the second opposing surface 41 when the camera body 3 is in the ready position. Meanwhile, the wire 8 may be housed between the first opposing surface 22 and the second opposing surface 41 or may be detached from the attachment portion 44 when the camera body 3 is in the imaging position.

[0021] The outer peripheral wall 42 is continuous in the circumferential direction so as to surround the second opposing surface 41. Furthermore, the tip of the outer peripheral wall 42 protrudes beyond the second opposing surface 41 toward the bracket 2 (the side opposite the imaging unit 6) when the camera body 3 is in the imaging posture. Furthermore, the outer surface 49 of the outer peripheral wall 42 according to this embodiment has an arc shape. However, the shape of the outer surface 49 of the outer peripheral wall 42 is not limited to the example described above.

[0022] A notch 45 is formed in the outer peripheral wall 42. The notch 45 is a recessed portion that is recessed from the tip of the outer peripheral wall 42 toward the second opposing surface 41 at one location in the circumferential direction of the outer peripheral wall 42. More specifically, the notch 45 is provided in a position that is closest to the bracket 2 when the camera body 3 is in the preparation position. Furthermore, the notch 45 is closed by the locking member 10 attached to the bracket 2 when the camera body 3 is in the imaging position. More specifically, the lower surface 117 of the locking member 10 fits into the notch 45, thereby filling the space of the notch 45.

[0023] The cutout 45 is a space surrounded by a pair of vertical sides 46, 47 and a rear side 48. The size and shape of the cutout 45 are set to be the same as those of the lower surface 117 of the locking member 10. The pair of vertical sides 46, 47 are arranged spaced apart in the circumferential direction of the outer peripheral wall 42. The pair of vertical sides 46, 47 extend parallel to each other along the protruding direction of the outer peripheral wall 42. The rear side 48 connects the rear ends of the pair of vertical sides 46, 47 (the ends opposite the tip of the outer peripheral wall 42) to each other. The rear side 48 extends along the circumferential direction of the outer peripheral wall 42.

[0024] The arm 5 has a generally cylindrical outer shape. The arm 5 connects the base 4 and the imaging unit 6. More specifically, of the two axial ends of the cylindrical arm 5, one end is connected to the end face opposite the second opposing face of the base 4, and the other end is connected to the imaging unit 6. Furthermore, a space is provided inside the arm 5 through which a cable 43 extending from the camera body 3 toward the base 4 passes.

[0025] The imaging unit 6 is a unit that captures images of the surroundings. The imaging unit 6 is an integrated (unitized) image sensor, a lens that collects external light and makes it incident on the image sensor, etc. The image sensor is, for example, a CMOS (Complementary Metal-Oxide-Semiconductor) or a CCD (Charge-Coupled Device).

[0026] The shade 7 is a part that covers the imaging unit 6. The shade 7 adjusts the amount of external light that enters the lens of the imaging unit 6. The shade 7 moves forward and backward (forward and backward) along the direction in which the arm 5 extends, for example.

[0027] 1, the arm 5 and imaging unit 6 are configured to be rotatable about a rotation axis L1 relative to the base 4. The imaging unit 6 is also configured to be rotatable about the rotation axis L1 relative to the arm 5. The imaging unit 6 is also configured to be rotatable about a rotation axis L2 relative to the arm 5. The rotation axis L1 passes through the centers of the arm 5 and the imaging unit 6, and extends in the Z direction when the camera body 3 is in the imaging posture. The rotation axis L2 passes through the tip of the arm 5, and extends in the X direction when the camera body 3 is in the imaging posture.

[0028] The camera body 3 can change its position between the imaging position shown in FIG. 1 and the preparatory position shown in FIG. 3. The imaging position is the position of the camera body 3 fixed to the bracket 2 with the first opposing surface 22 and the second opposing surface 41 facing each other. The imaging position is the position of the camera body 3 in which imaging by the imaging unit 6 is possible. The preparatory position is the position of the camera body 3 temporarily fixed to the bracket 2 with the first opposing surface 22 and the second opposing surface 41 exposed. The preparatory position is the position of the camera body 3 for preparations (for example, connecting cables 25, 43) to enable imaging by the imaging unit 6. "Temporary fixation" refers to a state in which the bracket 2 and the camera body 3 are connected by the cable 43 and the camera body 3 is locked by the locking member 10. The "temporary fixation" refers to temporary fixation of the bracket 2 and the camera body 3 for connecting the cables 25, 43.

[0029] [How to assemble surveillance camera 1] Fig. 5 is a flowchart showing a method for assembling the surveillance camera 1. The method for assembling the surveillance camera 1 (the procedure for installing the surveillance camera 1 on the wall W) will be described with reference to Figs. 1 to 5. The work shown in Fig. 5 can be performed by a single worker.

[0030] First, as shown in Fig. 2, a worker attaches the bracket 2 to a predetermined position on the wall W (S1). More specifically, the worker attaches the bracket 2 to the wall W with the attachment surface 21 facing the wall W and the locking member 10 positioned at the lower end. There are no particular limitations on the specific method for attaching the bracket 2, but fixing with bolts is one possible example. Step S1 is an example of an attachment step.

[0031] Next, as shown in FIG. 3, the worker connects the first opposing surface 22 and the second opposing surface 41 with the wire 8 by engaging the other end of the wire 8, one end of which is attached to the mounting portion 44, with the locking portion 23 (S2). The worker also locks the rear side 48 of the outer circumferential wall 42 with the locking member 10 (S3). In step S3, the locking member 10 enters the cutout 45 and abuts against the rear side 48. In other words, the rear side 48 is positioned between the main body 110 and the claw 130. As a result, the camera body 3 is temporarily fixed to the bracket 2 and takes the ready position. Steps S2 to S3 are an example of a temporary fixing step. The positional relationship between the locking member 10 and the outer circumferential wall 42 when the camera body 3 is in the ready position will be described later with reference to FIGS. 8 to 10.

[0032] Next, the worker connects cable 43 to cable 25 extending from bracket 2 (S4). At this time, since camera body 3 is temporarily fixed to bracket 2, the worker does not need to continue holding camera body 3 and can use both hands to connect cable 43. Step S4 is an example of a connecting step.

[0033] Next, as shown in FIG. 1 , the worker releases the locking member 10 from locking the camera body 3, and fixes the camera body 3 to the bracket 2 with the first opposing surface 22 and the second opposing surface 41 facing each other (S5). As a result, the camera body 3 is fixed to the bracket 2 and assumes an imaging posture. There are no particular limitations on the specific method for fixing the camera body 3 to the bracket 2, but fixing with a bolt is conceivable, for example. The worker also aligns the position of the locking member 10 with the notch 45 and fixes the camera body 3 to the bracket 2. As a result, the notch 45 is blocked by the locking member 10. Step S5 is an example of a fixing step.

[0034] [Configuration of locking member 10] Fig. 6 is a perspective view of the locking member 10. Fig. 7 is a three-view diagram of the locking member 10. Note that Figs. 6 and 7 illustrate the X, Y, and Z directions on the assumption that the bracket 2 is attached to a wall W. As shown in Figs. 6 and 7, the locking member 10 mainly includes a main body 110, a protruding portion 120, and a claw 130. The locking member 10 is integrally molded, for example, by injection molding a resin material.

[0035] The main body 110 has a roughly rectangular parallelepiped outer shape. The main body 110 is attached to the first opposing surface 22 of the bracket 2. The main body 110 is composed of a rectangular main wall 111 perpendicular to the Z direction, and a side wall 112 that protrudes in the Z direction from the outer edge of the main wall 111 toward the bracket 2 and continues circumferentially to surround the main wall 111. Here, in the Z direction, the surface of the main wall 111 that faces the bracket 2 is referred to as the back surface, and the surface of the main wall 111 opposite the back surface is referred to as the front surface 113. In addition, in the Z direction, the direction from the main wall 111 toward the bracket 2 is referred to as the inward Z direction. The direction opposite to the inward Z direction, i.e., the direction from the main wall 111 toward the external space in the Z direction, is referred to as the outward Z direction. In addition, in the Y direction, the direction toward the ground is referred to as the bottom side, and the opposite side is referred to as the top side. Further, the surface 113 of the main body 110 is provided with a protruding portion 120 extending outward in the Z direction and a claw 130 extending downward from the protruding portion 120.

[0036] The main wall 111 is formed with a bolt hole 114 and an opening 115. The bolt hole 114 penetrates the main wall 111 in the Z direction at a position that does not overlap the protrusion 120 and the claw 130 when viewed from the Z direction. A bolt for fixing the locking member 10 to the first opposing surface 22 is inserted into the bolt hole 114. The opening 115 penetrates the main wall 111 in the Z direction at a position that overlaps the claw 130 when viewed from the Z direction. That is, the opening 115 is provided at a position that faces the inner surface of the claw 130 in the Z direction. In other words, the widths of the opening 115 in the X and Y directions are wider than the widths of the claw 130 in the X and Y directions when viewed from the Z direction. In other words, the opening 115 is provided in a range that encompasses the entire claw 130 when viewed from the Z direction. The openings 115 are provided to allow the outer peripheral wall 42 to abut against two points on the surface 113 of the main wall 111, as will be described later with reference to FIG.

[0037] The side wall 112 is provided with a slit 116 extending outward in the Z direction toward the main wall 111. The slit 116 is a portion that receives the tip of the outer peripheral wall 24 of the bracket 2 when the locking member 10 is attached to the bracket 2. The inner end of the side wall 112 in the Z direction abuts against the first opposing surface 22 when the locking member 10 is attached to the bracket 2. The surface of the side wall 112 of the locking member 10 that faces downward when the bracket 2 is attached to the wall W is referred to as a lower surface 117. The lower surface 117 is located outside the outer peripheral wall 24 when the locking member 10 is attached to the bracket 2. The lower surface 117 has the same curvature as the outer surface 49 of the outer peripheral wall 42 of the base portion 4. The lower surface 117 closes the notch 45 when the camera body 3 is attached to the bracket 2.

[0038] The overhanging portion 120 is provided between the bolt hole 114 and the opening 115 in the Y direction. The overhanging portion 120 overhangs outward in the Z direction from the surface 113 of the main wall 111 and extends in the X direction. A plurality of reinforcing ribs 121 are provided between the main wall 111 and the overhanging portion 120. The reinforcing ribs 121 connect the surface 113 of the main wall 111 and the surface of the overhanging portion 120 opposite the claw 130. The reinforcing ribs 121 are walls perpendicular to the X direction. The multiple reinforcing ribs 121 are provided at a plurality of positions spaced apart in the X direction. The reinforcing ribs 121 reinforce the claw 130 that engages the camera body 3.

[0039] The claw 130 extends downward in the Y direction from the tip of the overhanging portion 120. The claw 130 also extends in the X direction. However, the width of the claw 130 in the X direction is narrower than the distance between the pair of vertical sides 46, 47. The length of the claw 130 in the X direction is shorter than the length of the overhanging portion 120 in the X direction. Furthermore, the claw 130 is spaced a predetermined distance in the Z direction from the surface 113 of the main wall 111. However, the distance in the Z direction between the main body 110 (main wall 111) and the claw 130 is greater than the radial thickness of the outer peripheral wall 42. This allows the locking member 10 to enter the notch 45. In other words, the rear side 48 can enter between the main body 110 and the claw 130.

[0040] The claw 130 extends downward in the Y direction along the surface 113. The claw 130 is divided into a base end 132 and a tip end 133 in the Y direction, with a midpoint 131 in between. The base end 132 is a portion of the claw 130 that is closer to the protruding portion 120 than the midpoint 131. The tip end 133 is a portion of the claw 130 that is farther from the protruding portion 120 than the midpoint 131. The midpoint 131 is not limited to the midpoint of the claw 130 in the Y direction (a position equidistant from both ends), but merely indicates the boundary position between the base end 132 and the tip end 133.

[0041] The thickness dimension in the Z direction of the base end portion 132 is constant throughout the entire area in the Y direction. On the other hand, the thickness dimension in the Z direction of the tip portion 133 in the Z direction gradually decreases toward the lower side in the Y direction (i.e., the tip of the claw 130). In other words, the tip portion 133 of the claw 130 has a tapered shape. More specifically, an inclined surface 134 is provided on the surface of the tip portion 133 of the claw 130 that faces the surface 113 of the main body 110. The inclined surface 134 is inclined in a direction away from the main body 110 toward the tip of the claw 130. The inclined surface 134 functions as a guide surface that guides the outer peripheral wall 42 (more specifically, the rear side 48) to enter between the main body 110 and the claw 130.

[0042] Furthermore, a stress relief portion 135 is provided between the overhang portion 120 and the claw 130. The stress relief portion 135 is provided at the perpendicular corner between the overhang portion 120 and the claw 130. The stress relief portion 135 has an arc-shaped outer surface. The stress relief portion 135 extends in the X direction. The stress relief portion 135 serves to relieve stress from concentrating at the corner between the overhang portion 120 and the claw 130 when the camera body 3 is temporarily fixed to the bracket 2.

[0043] [Positional Relationship Between the Locking Member 10 and the Outer Wall 42] Fig. 8 is a view of the locking member 10 and the outer peripheral wall 42 as viewed from the X direction. Fig. 9 is a view of the locking member 10 inserted into the notch 45 as viewed from the Z direction. Fig. 10 is a cross-sectional view of the locking member 10 and the outer peripheral wall 42 passing through the opening 115 and perpendicular to the Y direction (cross-sectional view taken along line XX in Fig. 9). The positional relationship between the locking member 10 and the outer peripheral wall 42 when the camera body 3 is locked to the bracket 2 will be described with reference to Figs. 8 to 10.

[0044] First, as shown in FIG. 4 , a moment M1 about the first axis Ax1 acts on the camera body 3 due to gravity acting on the center of gravity G, which is farther from the bracket 2 than the mounting portion 44. The first axis Ax1 refers to a horizontal line parallel to the wall W. A horizontal line parallel to the wall W is a line that passes through the mounting portion 44 and extends in the X direction. In contrast, as shown in FIG. 8 , the tip of the rear side 48 of the outer peripheral wall 42 abuts against the surface of the claw 130 facing the main body 110 (position A). Furthermore, the outer surface 49 of the outer peripheral wall 42 abuts against the surface 113 of the main body 110 (position B). More specifically, a portion of the outer surface 49 of the outer peripheral wall 42 that is lower in the Y direction than the rear side 48 abuts against an end of the surface 113 that is lower in the Y direction than the opening 115. The surface of the outer peripheral wall 42 that faces the surface 113 is referred to as the outer surface 49. In this way, the locking member 10 locks the outer peripheral wall 42 at positions A and B, thereby restricting the camera body 3 in the ready position from rotating around the first axis Ax1 due to the moment M1.

[0045] Furthermore, when the worker's hand or body hits the base portion 4 during the connection operation (S4), a moment M2 about the second axis Ax2 acts on the camera body 3, as shown in FIG. 9. The second axis Ax2 refers to a line perpendicular to the wall W. The line perpendicular to the wall W is a line that passes through the mounting portion 44 and extends in the Z direction. When the camera body 3 attempts to rotate due to this moment M2, the pair of vertical sides 46, 47 abut against the protruding portion 120. More specifically, the pair of vertical sides 46, 47 abut against the side surface 120a of the protruding portion 120. In this way, the locking member 10 restricts the camera body 3, which is in the ready position, from rotating about the second axis Ax2.

[0046] 10, a portion of the outer surface 49 of the outer peripheral wall 42 that has entered between the main body 110 and the claws 130 can enter the opening 115. This makes it easier for the outer peripheral wall 42 to enter between the main body 110 and the claws 130. In addition, the outer surface 49 of the outer peripheral wall 42 can abut against the main body 110 (more specifically, the main wall 111) at two points on either side of the opening 115 in the X direction. This allows the camera body 3 to be locked more stably than if the outer peripheral wall 42 were to abut against one point on the main body 110.

[0047] [Effects of the embodiment] According to the above embodiment, the worker can perform the connection work (S3) with both hands by temporarily fixing the camera body 3 in the ready position to the bracket 2 with the wire 8 and the locking member 10. This makes it easy to perform the connection work.

[0048] Furthermore, according to the above embodiment, by providing the mounting portion 44 at a position closer to the bracket 2 than the center of gravity G, the camera body 3 can be locked to the locking member 10 against the moment M1. This allows the camera body 3 in the standby position to be stably locked to the bracket 2. As a result, the connection work can be easily performed.

[0049] Furthermore, according to the above embodiment, the camera body 3 can be temporarily fixed to the bracket 2 at the correct circumferential position by inserting the locking member 10 into the notch 45 formed at one circumferential location on the outer peripheral wall 42. This prevents the cable 43 from twisting when the camera body 3 is in the imaging posture. In other words, the notch 45 is used to position the camera body 3 in the circumferential direction relative to the bracket 2. However, from the perspective of locking the camera body 3 to the bracket 2, the notch 45 can be omitted. Instead of the notch 45, a mark formed on the outer peripheral wall 42 may be used to position the camera body 3.

[0050] Furthermore, according to the above embodiment, the tip of the rear side 48 abuts against the claw 130 at position A, and the outer surface 49 of the outer peripheral wall 42 abuts against the surface 113 of the main body 110 at position B. This makes it possible to prevent the camera main body 3 in the ready position from rotating around the first axis Ax1 due to moment M1. As a result, the connection work can be easily performed.

[0051] Furthermore, according to the above embodiment, by providing the opening 115 in the main wall 111, it becomes easier to insert the outer peripheral wall 42 between the main body 110 and the claws 130. Furthermore, by abutting the outer surface 49 of the outer peripheral wall 42 at two points on either side of the opening 115, the camera main body 3 can be more stably locked to the bracket 2. As a result, the connection work can be easily performed.

[0052] Furthermore, according to the above embodiment, by positioning the pair of vertical sides 46, 47 in positions where they can come into contact with the protruding portion 120 when the locking member 10 enters the cutout 45, the camera body 3 can be locked to the locking member 10 against the moment M2. This allows the camera body 3 in the standby position to be locked to the bracket 2 more stably. As a result, the connection work can be performed easily.

[0053] Furthermore, according to the above embodiment, by providing the inclined surface 134 at the tip of the claw 130, the rear side 48 can be smoothly inserted between the main body 110 and the claw 130. As a result, the assembly of the surveillance camera 1 becomes even easier.

[0054] Furthermore, according to the above embodiment, when the camera body 3 is in the imaging posture, the locking member 10 closes the notch 45, thereby preventing dust, insects, water droplets, and the like from entering between the bracket 2 and the base 4. This allows the surveillance camera 1 to operate outdoors for a long period of time. However, the locking member 10 may be removed before the camera body 3 is placed in the imaging posture. Then, the cable 43 may be extended from the opened notch 45.

[0055] Furthermore, according to the above embodiment, by using the locking member 10, it becomes possible for a single worker to easily assemble the surveillance camera 1.

[0056] Although various embodiments have been described above with reference to the drawings, it goes without saying that the present disclosure is not limited to such examples. It is clear that a person skilled in the art can conceive of various modifications, alterations, substitutions, additions, deletions, and equivalents within the scope of the claims, and it is understood that these also naturally fall within the technical scope of the present disclosure. Furthermore, the components of the various embodiments described above may be combined in any manner without departing from the spirit of the invention. [Explanation of symbols]
