Security cameras from Lorex use infrared LED lights around the lens to shine invisible infrared light on the scene in front of the camera. The camera sensor sees this infrared light reflected on the scenery, which allows it to construct a visible image for us to see, even in total darkness. With most infrared security cameras there is an automatic shift from full color to black and white video when lighting conditions drop at night. This is because infrared light does not fall within the color segment of the electromagnetic spectrum (this is also the reason why humans cannot see infrared light). Security cameras with Color Night Vision, however, contain especially powerful image sensors that are more sensitive to light. This allows the sensor to absorb more visible light, which allows the cameras to continue to provide color in low-light conditions.
