Darkness is the enemy of security system setups. Unless you have an infrared security camera, as infrared security cameras excel at capturing video in the dark.

Let’s start out by acknowledging a infrared security camera’s obvious drawback: they capture black and white video. With that said, we can begin to speak about the benefits of having an infrared security camera in your security setup and the different types of infrared cameras.

Simply put, black and white video is better than no video and there are many situations where traditional cameras cannot capture anything.

A good security consultant will understand that there are often variables that will be outside of your control. Configuring a CCTV setup, has to plan for the unexpected such as a key light burning out, getting shattered, or having their power cut. Installing a infrared security camera functions as a tremendous failsafe for these conditions. Also, many times it is more economical, considerate, discrete, or otherwise preferred to use infrared security cameras outdoors rather than flood lighting.

Infrared security cameras measure infrared radiation (or IR). Infrared radiation sensors are often called heat sensors, as they are used in heat seeking missiles and night vision goggles. But this is a misconception as heat is felt from more than just infrared spectrum and the infrared spectrum contains more than heat (for example, your television remote uses an infrared sensor and infrared light, but does not get hot when you use it). For purposes of security systems, however, we will be primarily concerned with the infrared sensor picking up heat signatures of human bodies.

When selecting a infrared security camera it is helpful to know the location where you will be installing it. Infrared light sensors works differently than cameras which work well in ambient light. You will need a light with larger and/or more numerous bulbs if the area you would like to capture is farther away.

An infrared security camera can be very sensitive, which is why it is important to know where you will use it before you decide upon a model. Many people often assume that more infrared light bulbs will make a better picture, but often when a infrared security camera is used inside the amount of infrared light produced can reflect off of hard surfaces and wash out the infrared sensor. Some infrared reflective surfaces include anything flat and made of glass or metal (such as doors, mirrors, or windows) or even some “glossy” style interior paints.
