When designing intrusion systems, a number of sensor types can be selected, including:
- Glass Break
- PE/PIR/Laser Motion
- Inductive Loop
- Pressure Pad
While magnetic contacts may be most common, there are most likely multiple devices to choose from and some that may even be better suited for the application.
In this guide, we explain each sensor type, how much they cost, where they are typically used and their comparative strengths and weakness.
