[0030] Working principle: When working, the device is installed at the specified position through the bolts 19 and the fixing plate 18, and then the rotating plate 20 is driven by the motor 22 to rotate, so that the direction of the camera 2 can be adjusted, and the camera 2 can be rotated by controlling the extension of the electric telescopic rod 23, so that the inclination of the camera 2 can be adjusted to improve the detection range. The electric telescopic rod 23, the motor 22 and the camera 2 are all electrically connected to the Internet of Things terminal. When the camera 2 detects a portrait, the captured video is transmitted to the optical fiber transceiver of the Internet of Things terminal through the wire 5, and the optical communication module inserted in the optical fiber transceiver performs photoelectric conversion, and then the video is transmitted to the switch equipment in the user's computer room through the network cable, and a prompt is given to achieve an alarm warning effect; when the camera 2 is installed, first extend the wire 5 into the installation hole 27 through the opening 31 so that it is located below the arc-shaped pressing block 28, and then The adjusting screw 29 is turned to move the arc-shaped pressing block 28 downward and press and fix the wire 5, and the portion where the wire 5 and the camera 2 are connected is limited to prevent the portion where the wire 5 and the camera 2 are connected from being bent and damaged; when encountering rainy weather, the top plate 1 and the arc-shaped rain shield 24 are used to block rainwater and prevent rainwater from entering the camera 2. The setting of the side shield 25 can prevent raindrops from falling from the front of the camera 2 and prevent it from blocking the line of sight of the camera 2; when the camera 2 needs to be disassembled for inspection and maintenance, the rotating rod 17 is turned to drive the No. 2 bevel gear 16 to rotate, and the No. 2 bevel gear 16 drives the driving screw 14 to rotate through the No. 1 bevel gear 15, so that the driving block 12 drives the No. 2 mounting frame 9 away from the mounting plate 3 until the plug 11 is pulled out of the socket 10, and then the camera 2 can be removed, which greatly improves the convenience of later inspection and maintenance.

[0031] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description.
