An intruder alarm is a security system designed to detect unauthorized entry into a protected space. It typically consists of sensors strategically placed throughout a premises, such as motion detectors, door/window contacts, or glass break sensors. When triggered, the alarm emits a loud sound or activates a notification to alert occupants or a monitoring service. Modern systems may also integrate with home automation, allowing remote monitoring and control via smartphones. The primary goal is to deter intruders and provide timely alerts for swift response, enhancing the overall safety and security of the monitored area.
