Description

Technical Field

[0001] This application relates to the field of video surveillance, and in particular to cameras. Background Technology

[0002] Surveillance systems are among the most widely used security systems. Video surveillance systems, in particular, possess strong preventative capabilities due to their intuitiveness, accuracy, timeliness, and rich information content, and have been widely adopted in many situations in recent years. Cameras are a crucial component of video surveillance systems, used for image acquisition. Existing cameras are mounted using wall-mounted brackets, which include a first fixed part and a second fixed part that are rotatably connected. The first fixed part is fixed to the wall, and the camera is fixed to the second fixed part. The monitoring range of the camera can be adjusted by adjusting the angle between the first and second fixed parts. However, the wall-mounted bracket setup causes the camera to be in a tilted position, resulting in a tilted image captured by the lens, leading to a poor user experience. Utility Model Content

When the first lens assembly 31 pitches and rotates, the slider 3426 slides between the first stop block 3137 and the second stop block 3138 to limit the maximum pitch rotation angle of the first lens assembly 31.

[0083] In one embodiment, the slider 3426 is disposed on the housing 313, and correspondingly, the first stop block 3137 and the second stop block 3138 are disposed on the first ear portion 342.

[0084] In one embodiment, the slider 3426 is disposed on the housing 313 close to the second ear portion 343 side, and correspondingly, the first stop block 3137 and the second stop block 3138 are disposed on the second ear portion 343.

[0085] In one embodiment, the slider 3426 is disposed on the second ear portion 343. Correspondingly, the first stopper 3137 and the second stopper 3138 are disposed on the housing 313 near the side of the second ear portion 343.

[0086] In one embodiment, the maximum pitch rotation angle of the first lens assembly 31 is 270 degrees. The length between the first stopper 3137 and the second stopper 3138 can be adjusted according to actual needs to adjust the maximum pitch rotation angle of the first lens assembly 31.

[0087] Refer Figures 11 to 13 , the housing 11 includes a side wall 111 and a fixing plate 112 located within the space enclosed by the side wall 111 and connected to the side wall 111. The fixing plate 112 is provided with a through hole 1121. The limiting portion 346 of the connecting frame 34 passes through the through hole 1121 and is fixed to the limiting member 348. The outer diameter of the limiting member 348 is larger than the inner diameter of the through hole 1121 to limit the connecting frame 34 to the housing 11.

[0088] In one embodiment, the limiting member 348 and the limiting portion 346 are fixed by a second fixing screw member 42. The limiting member 348 is provided with a second limiting hole member 3481. The second fixing screw member 42 passes through the second limiting hole member 3481 and is assembled in the first limiting hole 3461 and is threadedly connected to the limiting portion 346.

[0089] In one embodiment, the limiting member 348 is provided with a third limiting hole 3482. The limiting column 3462 of the connecting frame 34 is located within the third limiting hole 3482 to facilitate the alignment of the first limiting hole 3461 and the second limiting hole 3481 to facilitate the assembly of the second fixing screw member 42.

[0090] When the limiting column 3462 is of a special shape, it can also prevent the relative rotation between the connecting frame 34 and the limiting member 348.

[0091] The host 100 includes a horizontal motor 35. The horizontal motor 35 drives the connecting frame 34 together with the first lens assembly 31 to horizontally rotate relative to the housing 11 along its circumferential direction to adjust the monitoring range of the first lens assembly 31.

[0093] In one embodiment, the horizontal motor 35 is capable of driving the connecting frame 34 together with the first lens assembly 31 to rotate horizontally 360 degrees relative to the housing 11. The horizontal rotation angle of the connecting frame 34 together with the first lens assembly 31 can be adjusted according to actual requirements. For example, the horizontal rotation angle of the connecting frame 34 together with the first lens assembly 31 can be limited by the cooperation of a slider and a stop block.

[0094] Through the pitching rotation and horizontal rotation of the first lens assembly 31 of the camera, the monitoring range is expanded. Moreover, due to the provision of the vertical motor 33 and the horizontal motor 35, there is no need to manually adjust the pitching rotation and horizontal rotation of the first lens assembly 31, making it more convenient to use.

[0095] In one embodiment, the horizontal motor 35 is located above the fixing plate 112 and is fixed to the fixing plate 112.
