SECURITY APPARATUS AND SYSTEM

摘要

A security system according to an embodiment of the invention includes motion sensor units for positioning at desired locations of a building structure. Each motion sensor unit includes a motion sensor adapted for detecting motion external to the building structure. The system can include a mobile alarm display unit operatively connected to the motion sensor units. The mobile alarm display unit can include a plurality of alarm indicators corresponding to the motion sensor units. Each alarm indicator can be operatively linked to a particular one of the motion sensor units, and detection of motion by the particular motion sensor unit activates the corresponding alarm indicator linked to the particular motion sensor unit.

1. A security system comprising:
(a) at least one motion sensor unit for attaching to a building structure, the motion sensor unit housing a sensor section comprising a motion sensor adapted for detecting motion, and a shield section adjacent to an inner surface of the sensor section, the shield section comprising shielding material providing a barrier to the sensor section and blocking the sensor from detecting motion proximate the inner surface of the sensor section, whereby the sensor does not detect motion occurring internally of the building structure when the sensor unit is positioned with the shield section facing the interior of the building structure; and (b) alarm means operatively connected to the at least one motion sensor unit whereby detection of motion by the sensor activates the alarm means.
