Independent studies clearly show that premises with alarm systems are less likely to be broken into. As illustrated by these studies, electronic alarm systems, without question, contribute to a safer environment for you and your family.

An alarm system is installed to deter and detect intruders. A basic security system will consist of both perimeter and space protection to secure your premise. The first stage secures vulnerable perimeter access points such as doors and windows.

The second stage consists of space detection such as interior motion detectors which monitor movement inside the premise. The level of security you purchase is determined by the number of protective devices and the sophistication of the system you will have installed.
