How ColorX Technology Turn Night into Day
Reolink App v4.41 Released
I saw 3 guys with a van parked so close to the back door of my store. I have the recording right here. I’m just wondering that is there any ways that I can see their license plate.59688C16-2B95-4719-903F-E2873EDE52F4.jpg
The coatings used in license plates, traffic sign plates, and special work clothes all contain retro reflective materials. The characteristic of retro reflectivity is that when light is irradiated, the reflected light will be reflected toward the light source from the opposite direction close to the incident light. This is to clearly identify people and objects with retro reflective materials in the distance at night or when the vision is poor, which plays a major role in ensuring traffic safety and other fields.Camera night monitoring mainly relies on the diffuse reflection of infrared light / white light from the object. After turning on the infrared light / white light, the infrared light / white light will irradiate the license plate, and it will be directly reflected from the license plate back to the lens, causing the license plate to appear as white sequins in the output image.
