The security monitoring system is widely used in various fields. With the development of information technology, Starlight lens has gradually occupied the entire security market in various parks, factories, restaurants and other scenes. As the main accessory of the main camera, the lens is more and more popular with the public. So, what is a starlight lens? Starlight camera usually means that there is no auxiliary light source in the starlight environment and it can display clear color images, which is different from ordinary cameras that can only display black and white images. No infrared light or white light is required, and clear color monitoring can be achieved at night.

The star level camera belongs to a kind of low illumination camera. Low illumination camera refers to the image that can still display clear color image at low light intensity. Starlight can also be divided into starlight and super starlight cameras according to the illuminance. Generally, a picture that can still maintain full color under the illuminance of 0.01 Lux is called starlight;

The full-color image can still be maintained in the weak light environment with the illumination of 0.001 lux, which is called the super starlight.

The concept of black light camera was first proposed by Haikang. Compared with Starlight, the night vision effect is better. The dual sensor architecture, based on the principle of human eye bionics, optimizes the processing ability of image color and brightness, effectively improves the monitoring effect of low illumination environment at night, and realizes the visual experience of color images.
