Yes, home alarm systems are designed to detect unauthorized entry and evidence of fire and report it to central station and dispatch the local police. It’s the fear of detection and reporting that prevents burglaries. Reporting consists of a loud bell or siren that sends most burglars running then having the signal monitored by an alarm company that will notify the local police.

Burglars will enter through doors or windows accessible from the ground. Just closing and locking these accessible openings when you’re away is a basic burglary prevention step.
