Gently Reminder: The 850nm infrared light of illuminator, after power it on if you look straightly at the lens of Infrared illuminator, you could see the dark red glow on each ring of lens, but YOU could NOT SEE any light emitting from it To protect the sensor, please install the senor head down to avoid direct sun exposure Camera and Illuminator should be installed to the same horizontal and vertical direction For after service and technical support, please mail us [email protected]. We are ready to help you JCHENG IR Illuminator, when the view angle of lens of illuminator is wider, the IR distance will be shorter. Moreover, the practical IR distance and view angle would be finally influenced by the focal length of lens of your camera.
