Home Improvement | The Science Behind the Infrared Security ...

A regular video camera is usually fine when recording videos by day, but they suck at night. They can?t record a decent video with low or no light conditions. That is why they are useless as video cameras. If you want to feel safe and secure, one can?t go wrong with an infrared security camera.

What is an infrared security camera, how does it work and why do you need it? Infrared cameras work regardless of whatever lighting conditions, despite having zero light. Thus, they can ?see? in the dark, to see whether a person is loitering around your property and attempt to burglarize your home or store.

The science behind this powerful video camera is the infrared technology. Infrared light is something we cannot see with our own eyes. Its wavelength is too long and the frequency too low to be seen by the naked eye. ?Infrared? literally means ?below red?, and our eyes are only designed to ?see? the colors of the spectrum, from red to violet.

An infrared security camera makes use of the infrared LED lighting that is positioned after the camera lens in order to capture information, even when there is zero light present. Rather then measuring light, infrared is able to measure heat coming from objects within the environment, and in turn can be read by the security camera. Infrared can travel fast through fog, smoke and dust, and even capable of traveling through some materials.

To measure the infrared camera?s quality, you need to know the camera?s lux. A lux is the amount of light necessary to produce a picture. The best infrared cameras have 0.0 lux because it can see perfectly in complete darkness. Aside from their ability at night vision, you have to see how far your camera can see in complete darkness. Some cameras can be of short range, while some are long range enough to see up to 150 feet in utter darkness. Depending on the size of your property, you can select which type of camera is useful for you.

Infrared cameras give you a clear and colored picture when light is available. As the lighting worsens, the camera gives you a black and white picture, meaning it has switched to the infrared mode. Not to be confused with day/night cameras, a day/night is very sensitive that can capture videos in the low light conditions. However, it does not make use of the infrared technology. Night cameras still need a light source though, like a street light or a security light, and will be unable to record videos when light is unavailable.

Infrared cameras can be used inside or outside. For inside cameras, the dome style is a useful type that is mounted on the ceiling, allowing a 360-degree surveillance. For outside cameras, go all out and invest in weatherproof bullet style models only that can survey a wide amount of area. Provide yourself, your family and your property the best protection whatever environmental and weather conditions it has to endure.
