Intrusion Motion Sensors Tutorial

Author: Brian Rhodes, Published on Oct 04, 2016

Motion sensors are one of the most common, and most useful alarm sensors, but they also often cause problems. Many motion sensors types exist and their suitability vary across applications. As such, knowing the differences in types and what impacts performance is key.

In this note, we examine:

  • 5 main sensor technology types including PIR, Multi-Tech, Photoelectric, Laser and Tomographic
  • 3 major factors that impact detection areas - detector type, interference tolerance and environmental impacts
  • 4 typical areas where motion detectors are used (offices, warehouses / large indoor areas, residential and perimeters), and which types are best

We address sensor limitations, prices, and more inside.
