An infrared camera works by calculating the brightness of a room or particular area. They feature special LED lighting which can be seen on the outside lens. These LEDs are able to capture light from the regions of electromagnetic spectrum that allow an image to be created even if there is little visible light. For this reason many people think of infrared cameras as having a night vision capability.

An infrared security camera will switch its mode to infrared only when the light drops below a certain level. It captures black and white images. It is important to understand that not all night cameras come with special LED lights, make sure you check out the specifications of any security system in full before investing.

This type of camera is available also as part of a fully integrated CCTV system. Many of the latest options also feature special IR Illuminators which can be focused on important objects such as access points and equipment. This helps to improve the overall surveillance whether in low light or in night. Technically, they may or not rely on the ambient light that is reflected but this is independent to actual light level.

Dessutom, the IR Illuminators allow any obscurants to be penetrated, such as the haze, fog and smoke. Infrared Illuminators are used typically for a low light environment. Sometimes, when the IR array is focused narrowly or the hold is not strong enough the external IR Illuminator will give an extra sharp image.
