Night vision function of Body worn camera instrument

The night-vision Body worn camera has three times the night-vision ability of the daytime, and can still clearly photograph the license plate number and the face of the person in the dark environment.
The Body worn camera can record clear images at night and in complex light environment, with strong practicability and operability There are three main ways to realize the night vision function of the law enforcement instrument. The first is to use infrared light directly in low-light environment, and the second is to combine the camera and software functions. The third is to add the night vision module to achieve coverage without dead spots. At present, most brands of products adopt these three methods.
In terms of practical application, night vision module and infrared light are not contradictory, as long as there is a night vision module.
Since the infrared light can only be used in certain environment, it is necessary to keep the environment dark enough for the law enforcement instrument to have excellent night vision effect.
In the dark, the law enforcement instrument can clearly capture the detailed features such as the facial expression of the detected person and improve the recognition rate. If the law enforcement instrument uses the camera to shoot, it needs large enough pixels to achieve clear imaging.
If we combine these two points, we can achieve excellent night vision effect.
So how does the law enforcement instrument choose the appropriate camera? Generally, when the light is relatively dark or the lighting environment is not very good, the wide-angle lens is the most appropriate choice.
Wide-angle lens not only has wide-angle effect but also has large imaging area, which can effectively image at night.
If there are not enough pixels, then any good night shot is in vain.
