When a door or window is opened, it closes the circuit and sets the alarm. A closed-loop system operates in the opposite direction - if a door or window is opened, it breaks the circuit and triggers the alarm.
Motion is a slightly more sophisticated option. They sense movement in a certain area around the sensor. When motion is perceived, is a signal to the control panel, which analyzes them to sendsee if it is enough movement to be suspicious.
The sensitivity of these motion sensors can be adjusted to account for things like air movement that might rustle papers or pets walking around the house.
