Infrared Security Cameras – For Your Safety And Peace Of Mind

Infrared light is visible as red or violet, which is translated by electromagnetic waves. Some waves are very short, and others are longer, similar to microwaves. When it comes to surveillance, there is no better way to do this than by using 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.

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.

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.

One thing you should make sure of is, can your IR camera see everything in its range? This is true especially for night surveillance or when an area is completely in the dark. Some inexpensive cameras that use infrared illuminators light up the center of the picture but the outer edges will be much less bright or even dark. A good IR camera will have lighting to match the viewing angle of the lens.

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 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.

Having this type of technology work for you has become so easy. Today the average camera is lightweight, durable and above all very easy to install or have installed.

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.
