CCTV offers more than 30 night vision Infrared (IR) cameras with various illumination ranges and resolutions.

In its simplest terms, Infrared (IR) energy is light that we cannot see. It is part of the electromagnetic spectrum that includes radio waves, X-rays and visible light. IR imaging is used extensively in video surveillance applications. IR is used when there is insufficient visible light to see. IR increases in-the-dark visibility without actually using a visible light source.

The use of IR light and night vision devices should not be confused with thermal imaging which creates images based on differences in surface temperature.
