[0002] A dynamic video acquisition device is a device used to capture dynamic image content in the real world, such as a camera or a camcorder. Its working principle is mainly based on the acquisition and processing of analog or digital signals. In analog video acquisition, the camera or camcorder converts the optical image into an analog electrical signal, and then converts the analog signal into a digital signal through a video capture card or other device, and then transmits it to a computer or other device. In digital video acquisition, the camera or camcorder directly converts the optical image into a digital signal, and then transmits it to a computer or other device. In daily life, the camera is generally fixed to the top of the pole with fixing bolts, and the position is relatively high. When it needs to be inspected and disassembled, maintenance personnel also need to use tools such as ladders to reach the height of the camera for inspection, which is very troublesome, and due to the high position, it is relatively dangerous.
