Answer:
A motion sensor (or motion detector) is the linchpin of your security system because it detects when someone is in your home when they shouldn’t be. A motion sensor uses one or multiple technologies to detect movement in an area.
When a sensor detects motion, it sends a signal to your security system’s control panel, which connects to your monitoring center. This alerts you and the monitoring center to a potential threat in your home.
