Motion Sensors

Motion sensors are the key to your perimeter security system because they detect movement. These devices use one or more technologies, like radar waves, infrared technology, and sound vibration technology.

Motion sensors send signals when there is anything moving in their field of view. They connect directly to a monitoring center where security staff can take action quickly against potential threats.

What is a motion sensor?

A motion sensor is a device that detects movement within its field of view. Motion sensors are used in various applications, including perimeter and infrastructure security.

Motion sensors can be classified into two categories: passive and active. Passive motion sensors rely on the detection of thermal energy or electromagnetic radiation emitted by objects in their field of view. Active motion sensors generate their signal and detect changes in that signal caused by movement.

Motion sensors are often used in conjunction with other security devices, such as CCTV cameras, to provide enhanced security protection.

Types of Motion Sensors

There are a few different types of motion sensors that are commonly used in security applications.

  • Passive infrared (PIR)
  • Microwave Sensors
  • Dual technology motion sensors
  • Area reflective sensors
  • Ultrasonic motion sensors
  • Vibration motion sensors
  • Contact sensors
  • Radio wave motion sensors
  • Optical motion sensors
