What is alarme intrusion?

An intrusion alarm (alarme intrusion in French) is a security system designed to detect unauthorized entry into a building or area. It typically consists of sensors that detect intrusions, such as door/window contacts, motion detectors, and glass break detectors. When a breach is detected, the system triggers an alarm, which may be a siren, a notification to a monitoring center, or a message to the owner. These systems are commonly used in homes, businesses, and other properties to deter burglars and alert occupants and authorities to potential threats.
