Having a security alarm system decreases the chances of burglary. Even if the alarm system does not keep a burglar from breaking in, it may cause the burglar to stay a shorter amount of time. First Line of detection and alert.
Most systems rely on a combination of contacts placed at doors and windows and motion sensors. It is best that all exterior potential points of entry have contracts that sense when they are open. Glass break sensors are also available and recommended. Motion sensors should not be used as the primary means of detection because they do not detect someone until they are already in the house.

Motion Sensor: These sense charges in a room caused by human presence. Special motion detectors are available for people who have pets.
Door and window contacts: These sounds the alarm when the door or window is opened (and the system is on).
A central monitoring station ( ADT ): If the system is monitored, and the alarm is set off, the control panel sends a message to a central monitoring station, which is manned 24 hours a day.
After attempting to contact the homeowner, the central monitoring station will contact the police, fire department, or medics.
