Abstract
An intrusion detector for a security system that detects the breaking of a glass in a window or a door and motion within a protected area is provided. The intrusion detector includes a single sensing section, a first filter, a second filter, a microprocessor, and an alarm generating. The microprocessor includes a motion detection section, an activation section for activating the motion detection section for a preset period of time only when a detected acoustic signal is consistent with that required to break glass, and a timing section for timing the preset period. The sensing section is capable of sensing motion induced signals during both activation and non-activation of the motion detection section, but the motion detection section ignores motion-induced signals during non-activation of the motion detection section.
