The importance of laser night vision technology in the field of security

With the application of technologies such as networking and cloud computing, video surveillance has also entered the era of networking, high-definition, and cloud computing. However, although the clarity and intelligence level of video surveillance have improved, the demand for 24/7 clear monitoring has not been effectively realized. Currently, common infrared laser night vision devices
The infrared light source used is mostly an 850nm LED light source, which is limited by light intensity and heat dissipation level, making it difficult to achieve night vision fill light above 80m. Therefore, nighttime monitoring capability has become a weakness of traditional surveillance cameras.

1. By using laser infrared fill light technology, night vision fill light of 200 meters or even several kilometers can be achieved, which is incomparable to LED infrared light sources;
2. The sensitivity of CCD and CMOS chips to 808nm laser is about 30% higher than that of 850nm LED. Under the same illumination, 808nm laser night vision imaging is clearer;
3. The photoelectric conversion efficiency of semiconductor lasers is 2-3 times that of LED infrared, with lower laser energy consumption and longer lifespan.
