Everyday the world becomes more unsafe and we need to protect ourselves from all sorts of unwanted elements. There are excellent technologies out there that can be utilized for just that purpose. One of the technologies is infrared security cameras.
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.
Because infrared radiation can be measured and seen with special equipment, there are now many ways to view objects either totally in the dark or at normal conditions. Most important to understanding IR cameras is the concept that they provide their own light source. This is not true. Only when the light dims below a pre-set level will the camera's built in light source turn on.
Because infrared can be incorporated with particular equipment such as a camera, it can be used in complete darkness. How this translates is as soon as the level of light drops to its predefined setting, then its emitters kick in and start beaming infrared light at the area in question.
What's really helpful here is that the more emitters your camera is able to carry, the more your area of surveillance will increase. Make sure that your camera specifications can supply you with details like range and angle of its beam.
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.
If your existing system uses B/W cameras or cameras that turn B/W in low light, then there is also the option to install infrared illuminators. Then your camera will record motion in black and white by the use of infrared light which cannot be seen by the human eye. So your existing system without infrared will give you only coverage up until the light fades away. It will not record in a zero light area.
IR cameras come in a variety of sizes and types. The sizes can range from a small bullet cameras to larger bullet cameras which are the size of coffee cans. IR cameras can also be found in large block sizes that allow for a larger number of IR emitters.
If you are considering a closed circuit television security system you need to also consider the option of installing an infrared camera as well which will give you optimal coverage at night, when it's needed the most.
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.
Before you buy any infrared security cameras, take some time to compare units as they vary in price and quality. Sometimes it's difficult to make a selection especially if buying online but any retailer or supplier should be able to tell you the differences in the cameras so that you can make an informed decision.
