We usually see the camera of the camera on the edge of the full infrared LED lamp, the LED lamp is mainly in low light or dark night, such a infrared radiation to the object or human body reflection back for imaging and recognition, so as to achieve the public safety protection and monitoring. But infrared LED in the work will often send out the red light, because the LED is a semiconductor chip (GaAs, silicon, etc.) made, through the electricity after the experience of heat. In particular, the process is more mature 850 infrared light-emitting tube, the phenomenon of the red burst. In the dark night, if someone saw the red light on the camera in the work, immediately remove the camera or away from the camera, it is not conducive to the normal monitoring. Now a practice is only through infrared brown plastic, the other one is infrared light in a different location, but this is not the best choice.

How can we eliminate this red light? Haian Hui Hong photoelectric R & D and production of infrared filter can effectively eliminate the red light.

This kind of filter from the naked eye see in the daytime or at night is essentially invisible, this product combined with infrared brown plastic filter plate through our, that kind of feeling is the day to see the shadow of the LED lamp. At night, can not see highlights of the LED lamp. Appearance high-grade generous. Is the main choice of high-end security cameras. At present, the security camera is more and more high-end, diversified products is the choice of our guests.

Rainbow also produced by the introduction of infrared transparent plastic, ultra strong solar light suppression 850nm narrow band filters. We welcome inquiries and customization.
