What is a perimeter alarm?

A perimeter alarm is a security system that detects and alerts when someone tries to enter a protected area or property. It is designed to monitor the boundaries or perimeter of a location and trigger an alarm if an unauthorized person or object crosses that boundary.


How Does a Perimeter Alarm Work?


Perimeter alarms typically use a variety of sensors and detectors placed along the edges or boundaries of a property. These can include motion sensors, infrared beams, pressure pads, or even buried cables that can detect disturbances. When the system senses any kind of intrusion, it will immediately sound an alarm and often notify the property owner or a security monitoring service.


Types of Perimeter Alarm Systems



  • Outdoor Perimeter Alarms: These are designed to monitor the exterior boundaries of a property, such as fences, walls, or the edges of a yard or field. They often use motion sensors, infrared beams, or buried cables to detect movement.

  • Indoor Perimeter Alarms: These are used to secure the interior perimeter of a building, such as doors, windows, and other entry points. They may use contact sensors, vibration detectors, or other specialized sensors.

  • Wireless Perimeter Alarms: These systems use wireless sensors and transmitters to communicate with a central control panel, making them easier to install and configure.

  • Wired Perimeter Alarms: These systems use physical wiring to connect the sensors and control panel, providing a more secure and reliable connection.


Perimeter alarms can be an effective way to enhance the security of a property by providing early detection of potential intruders. They can be customized to fit the specific needs and layout of a location, and can be integrated with other security systems for a comprehensive approach to protection.
