Abstract

The invention discloses an analog box camera comprising a zoom lens, a shell, and a video line interface. The zoom lens is arranged at the front end of the shell, and the zoom lens and the shell are fixedly connected. The video line interface is arranged in the rear end of the shell. An indicating lamp and a power line interface are arranged below the video line interface. A transcoder is arranged in the shell. The transcoder and the zoom lens are connected by an analog signal. The transcoder and the video line interface are connected by a digital signal. A zoom ring is arranged on the zoom lens. A fixing screw is arranged on the zoom ring, and the fixing screw is in threaded connection with the zoom ring and the zoom lens. One side of the shell is provided with an automatic aperture interface. The analog box camera is compact in structure, easy to carry, simple to operate, and good in recording effect.

Description

technical field [0001] The invention relates to the technical field of security equipment, in particular to a simulated gunlock. Background technique [0002] In the video surveillance system, the camera is the most front-end, most basic, and the most invested product, and it is also the most critical equipment. It is responsible for taking pictures of the surveillance area and converting them into electrical signals, which are further used for transmission. Its quality directly affects the video quality. The overall application of the monitoring system is also related to the project cost. Cameras can be classified according to three aspects. Classified by color: divided into color and black-and-white cameras, generally black-and-white cameras are more sensitive than color ones, and are more suitable for places with insufficient light. If the purpose of use is only to monitor the position and movement of the scene, black and white cameras can be used; if you want to disting...
