Background

The cameras are of various types, and the basic principle of operation is the same: the optical image signal is converted into an electrical signal for storage or transmission. When an object is shot, light reflected by the object is collected by a camera lens, so that the light is focused on a light receiving surface of an image pickup device (such as a target surface of an image pickup tube), and the light is converted into electric energy through the image pickup device, so that a video signal is obtained. The camera adjusting device is used for adjusting the visual angle or the monitoring direction of the camera.

The explosion-proof camera belongs to explosion-proof monitoring products and is a cross product of explosion-proof industry and monitoring industry. The explosion-proof camera is formed by installing a conventional camera into an explosion-proof shield.
