1. Infrared lamp, short for night vision monitoring infrared lamp, is a light supplement device that cooperates with the monitoring camera to collect images at night.
2. The light emitted by the infrared lamp, with the wavelength of 850nm and 940nm, is invisible and has the characteristics of concealment and energy saving. It has been widely used in the field of security monitoring in the past 10 years.
3. In terms of materials, infrared lamps can be divided into LED light-emitting diodes: currently, they are the most widely used, with high cost performance, and the effect is better when the monitoring distance is less than 150 meters.
4. 2. Laser infrared lamp: The irradiation distance is the farthest, which can reach more than 200-2000 meters, but the luminous angle is small.
