What's IR Illumination

Applies to: All Reolink cameras

At present, the infrared LED on the market is also known as infrared emission tube or infrared light. The wavelength is mainly 850nm, 940nm and 880nm, but 880nm is not commonly used (so we do not introduce it later). Here we'll introduce IR illumination from the following two aspects.

The Difference between 850nm and 940nm IR Illumination

Here're the main differences mostly concerned by the customers.

850nm has the red explosion while 940nm has NO red explosion. Also, the 850nm has more details and greater distances than the 940nm.

What's Red Explosion

It refers to that the infrared lamp displays visible red dots in working mode. Therefore, in need of concealment, 940nm IR Illumination is a good choice.

So far, Reolink adopts 850nm for all Reolink cameras.
