what it is?
A motion sensor (or motion detector) is the linchpin of your security system, because it’s the main device that 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.
how it work?
Motion sensors are devices made to detect activity. These can be used indoors or outdoors to enhance your home protection. Whenever an indoor sensor is tripped, a signal is sent to your security system’s control panel or base station, and then your monitoring company is notified.
From there, you may be contacted by your monitoring company or the authorities may be dispatched. It’s also important to note that some motion sensors can be self-installed and come with professional monitoring. This gives you the freedom to place them wherever you feel is best in your home.
