What's the difference between starlight cameras?

Difference:

In the case of weak light, it usually means that there is no auxiliary light source in starlight environment, and clear color images can be displayed, which is different from ordinary cameras that can only display black and white images. Without infrared light or white light, clear color monitoring can be realized at night without tailing.

Extended data:

There are many kinds of cameras, which are mainly composed of video circuits and audio circuits. The basic principle of its work is the same: converting optical image signals into electrical signals for storage or transmission. When shooting an object, the light reflected by the object is collected by the camera lens and focused on the light receiving surface of the camera device (such as the target surface of the camera tube), and then the light is converted into electric energy by the camera device to obtain a "video signal".

The photoelectric signal is very weak, so it needs to be amplified by pre-amplifier circuit and then processed and adjusted by various circuits. The final standard signal can be sent to video recorders and other recording media for recording, or spread through a propagation system, or sent to a monitor for display.
