A Perimeter/ Intruder alarm system is a system that monitors and detects unauthorized access in an area. These systems are used for different purposes and in different contexts both residential or commercial.

The main importance of a Perimeter alarm system is; warning occupants of an intrusion, scare away the intruder, notify the appropriate authorities that a break-in is occurring, or some combination of all of these.

`Integrating an Intruder Alarm system with a CCTV System greatly improves the security on an area.

Advantages: When the system sends notifications on phone or sirens or both, this minimizes damage of property, theft and loss of lives.
