Infrared cameras use LED lights around the lens to shine infrared light in front of the camera. A camera sensor then "sees" this infrared light and constructs a visible image. Due to poor lighting conditions at night, infrared cameras tend to drop in quality from full color to black and white. However, security cameras with color night vision have powerful image sensors that absorb more visible light, allowing color footage to be captured even in low-light conditions. For a home security camera capable of seeing color at night, check out the Arlo Pro 3.
