The Basics of Home Security Camera Systems

A surveillance camera in your home can not only deter burglars just by its presence, but it improves the police's chances of catching the burglar if one does break in. The huge selection of home security cameras on the market today means a camera is available that suits your needs, but it also makes it harder to find the right. Once you have an overview of the types of cameras and features available, you'll be better armed to find exactly what you need.

How You Can Use Your Home Security Camera
In terms of security, most cameras are used to keep an eye on the front and back doors and identify people before they enter. This way both you and, if you've installed a security system that's monitored off-site, the security company can keep out unwanted visitors. They may also be installed indoors so that if anyone does manage to break in, they'll be "caught on film" (or video, at least).

How Home Security Cameras Work
Home security cameras are CCTV cameras (closed circuit television) which broadcast the images they pick up over an closed circuit that is wired together. This is unlike regular TV, which broadcasts to an open network. While some cameras are designed to operate twenty-four hours a day, others contain a motion sensor that switches the camera on only when someone moves past it.

The Basic Components
The basic components of video security systems are:

--A security camera
There are many different formats, such as bullet and dome shaped, that may be designed for either indoor or outdoor use. They may also include features light infrared lights for "night vision", motion sensors, and panning and zooming capabilities.

--A display monitor
Although the monitor isn't as critical as the camera, choosing the right one can save you money in the long run. Make sure you choose a monitor that's designed to be left on for an extended period (TV monitors aren't a good choice). While computer monitors can work, you'll get the best results from a monitor specifically designed for use with security cameras. Also, look for a monitor that matches your camera's image resolution.
