Infrared Illumination for cameras Data transmission Sensor technology Smoke detectors
Notes
Depending on the mode of operation, these devices emit highly concentrated non visible infrared light which
can be hazardous to the human eye. Products which incorporate these devices have to follow the safety
precautions given in IEC 60825-1 and IEC 62471. Ordering Information
