An Introduction To Infrared Security Cameras
Infrared (IR) light is invisible light that the human eye cannot detect; this invisibility is attributed to the fact that infrared light makes use of longer wavelengths than is the case with the wavelength of light from the visible spectrum. Infrared security cameras therefore work on the premise of being able to capture images based on very little or no light. Light levels are actually measured in terms of 'lux'. A low lux rating enables a camera to see better in darkness and also when there is no light at all.
Most cameras that use infrared light will have lux ratings of 0 which of course means that such a camera will be able to see when there is absolutely no light around at all.
Some people even choose to use color infrared cameras that are able to switch over to taking black and white images in the dark, while in the daytime they provide color images. In order to determine whether to shoot in color or in black and white these cameras have photo cells inside the camera that monitors and keeps track of whether it is daylight or not.
The best IR camera is the outdoor IR camera. When picking your security camera (IR) you must look at factors such as the distance rating and also the cost of the camera. Remember that if you choose to buy an indoor camera that has a bigger range than the dimensions of your interiors, then the pictures taken will be less than perfect because of their inability to focus properly in limited areas.
Also, when it comes to purchasing these cameras you should be prepared to spend more money than is the case with purchasing an ordinary security camera. Though at the same time you will find a lot of choice in terms of style, and of course you can also buy some very high quality infrared security cameras as well.
You can purchase an IR security camera from many local surveillance or alarm companies, however many times you will find better deals and more selection from online security camera retailers.
The main purpose of using such security cameras is to provide surveillance over areas of a home or business premises that is not properly lit. They also to cover sensitive areas in the absence of proper lighting which may make it impossible for an ordinary security camera to capture images of the events taking place.
With the help of an IR security camera you can record events even when there is no lighting. Indoors such cameras can keep track of interiors even when the interiors are in total darkness.
Even if criminals get onto your premises and turn off the lights, the help of an IR security camera will still enable you to record the events as they take place. This provides you with ample evidence to help catch the criminals.
If you pay a little extra you can pick up better quality security cameras and this ensures that the footage provided will be of superior quality. Clear and crisp images can prove to be very helpful in tracking down criminals that have broken into your home or office.
