Infrared Security Cameras – Surveillance At It’s Best
Electromagnetic waves can also be used as infrared light which can be visible or transformed into microwaves. Looking at infrared visibly, the light can be seen as red or violet. This technology is greatly used in infrared security cameras which are extensively used for surveillance or property or spaces.
There's is a lot of technical information available but for the layman it would suffice to share only the information needed to source the correct system.
Infrared radiation can be incorporated and seen with particular equipment, which will allow us to view objects either totally in the dark or at regular conditions.
The IR camera either has built in emitters or they are on separate enclosures. The more emitters your camera has, the more it will light up the area of surveillance. Make sure that your camera identifies it's effective range and angle of it's beam.
A really good camera must be able to see everything in it's range, especially at night when there is little ambient light available. Some less expensive cameras with infrared will be bright in the center of the picture but the periphery or outer boundaries will be dark. A good camera should be able to provide infrared lighting to match the angle of the lens.
With the use of infrared illuminators, a regular surveillance camera that is B/W or turns to B/W in low light can be transformed into an infrared camera. This will allow your camera to record in black and white, using infrared radiation. How this works is the illuminator lights the area under surveillance with infrared light so that your regular camera can record black and white images with the use of infrared radiation, which is impossible for the naked eye to see.
Many regular surveillance cameras if they are capable of B/W images are transformed into infrared cameras as well, with the use of illuminators installed separately. Your camera when attached to a DVR can then detect motion in complete darkness, with the use of its infrared radiation, which is undetectable with the naked eye. Remember that while the normal day and night camera does records in low light, it is impossible to record in zero light as it does not utilize infrared technology.
IR cameras nowadays are manufactured in all shapes, types and sizes. There are sizes in the market which can start from as small as a couple of inches or as large as paint cans. If you require a very large area to be under surveillance then there are cameras that come in block sizes, so that they can hold more IR emitters, which equates into more infrared light.
If you are considering a CCTV system, then look into a infrared system that can work in tandem with its counterpart. This will provide you with maximum coverage especially at night.
Some years back it was cumbersome to have these cameras installed because of their bulkiness. Today they are lightweight, easy to install and much more durable than a few years back.
Lastly, when comparing different sizes, shapes and functionality, take time to get a supplier who will understand your exact needs. If you only want to have an entrance of a door monitored there is no need to purchase a large infrared security camera that can see 100 feet, when you only need a small camera with 12 to 20 LEDs to monitor one entrance.
