Sensors for home security systems


Sensors are used to check for disturbance such as movement and heat change in an otherwise "quiet" environment. When there is a change in the environment, the sensor is triggered causing it to send a signal to the control panel.

Sensors are essentially magnetic switches that trigger the alarm whenever a door or window is opened. One part of the switch is installed on the door or window frame; the mating part attaches to the door or the window sashes. When the unit is opened, separating the parts, the interruption in current triggers the alarm.
