A passive infrared motion detector discriminates between the motion of humans and pets in a premises. The motion detector includes an infrared sensor and a mirror for focusing infrared radiation from distinct fields of view. In one embodiment, a mask prevents infrared radiation from reaching the infrared sensor, and cut away regions on the surface of the mask allow selective passage of infrared radiation to the infrared sensor. In an alternative embodiment, the cylindrical mirror elements includes reflective and unreflective regions, which allow selective passage of infrared radiation to the infrared sensor. The cut away regions and the reflective regions are elongated to correspond to the shape of standing humans. As a result, the infrared radiation from animals only partially reaches the infrared sensor.

Passive infra-red intrusion detector

A method and device for omnidirectional and anti-sabotage anti-tampering detection are disclosed. For this purpose, a proposed security device assembly includes a mounting bracket, a security device such as a motion detector or surveillance camera, and an anti-tampering system. The security device is mounted via the mounting bracket. The anti-tampering system includes a permanent magnet and a magnetometer for detecting a magnetic field of the permanent magnet, and includes a controller. The controller detects changes in the magnetic field that are indicative of movement between the mounting bracket and the security device. In general, the anti-tampering system spans across the mounting bracket and the security device. Preferably, the permanent magnet is attached to the mounting bracket and the magnetometer is included within the security device.

Position detector

A system for automatically controlling intrusion thresholds of intrusion detectors deployed in a premises, the system including intrusion detector output receiving functionality operative to receive at least one output from at least a first intrusion detector deployed in the premises, intrusion detector output comparison functionality operative to compare the at least one output from the at least a first intrusion detector with at least one of a multiplicity of premises intrusion detection patterns, and intrusion detector threshold controlling functionality operative, in response to ascertaining that the at least one output from the at least a first intrusion detector matches at least one of the multiplicity of premises intrusion detection patterns, to automatically tune a threshold of at least a second intrusion detector deployed in the premises.
