IV.Overall Dimensions
V.Interface Definition
  • The Laser Infrared Lighting Modules belong to the class 3B non-visible light laser. While the laser light is on, back-light looking at or observing laser light beam with optical instrument is strictly prohibited.

  • While the Laser Infrared Lighting Module is on, flammable objects are strictly prohibited within 20cm in front of the lens to prevent fires.

  • The Laser Infrared Lighting Module should be installed where people could not look at it directly or it should be a long enough distance from where people could look directly. Manufactures should choose the Laser radiation power according to its actual application environment, in order to avoid hurting people's eyes.

  • Manufactures using our Laser Infrared Lighting Modules should put labels warning of laser radiation.

  • When device fault occurs, please contact with our qualified maintenance personnel for service rather than disassemble it at your own discretion, otherwise warranty will be end of the moment you disassemble it.
