A burglar alarm is a security system designed to detect unauthorized entry into a building and alert the occupants or authorities. It typically consists of sensors placed on doors, windows, and other entry points, along with a control panel that triggers an alarm when the sensors detect movement or forced entry. Some burglar alarms are connected to a monitoring service, which can contact the police or security personnel if the alarm goes off. These systems help protect homes and businesses from theft or break-ins by providing an early warning and deterring potential intruders.
