IR Illuminator is an acronym for night vision surveillance infrared light. It is a light supplement device for capturing images at night with a surveillance camera. The light emitted by the infrared lamp has two kinds of wavelengths of 850nm and 940nm, all of which are invisible light. It has the characteristics of concealment and energy saving. It has been widely used in the field of security monitoring in the past 10 years.
Infrared lamps can be divided into:
1, LED light emitting diodes: currently the most widely used, cost-effective, monitoring distance within 150 meters less effective.
2. IR Laser Illuminator: The irradiation distance is the longest and can reach 200-2000 meters, but the light emission angle is smaller.
