Security apparatus and system
First Claim
1. A security system comprising:
- (a) at least one motion sensor unit for attaching to a building structure, the motion sensor unit comprising 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;
(b) an alarm display unit comprising alarm means, and operatively connected to the at least one motion sensor unit whereby detection of motion by the sensor activates the alarm means; and
(c) wherein the at least one motion sensor unit further comprises an alarm section having an alarm light that activates upon the motion sensor detecting motion, and the shield section is positioned intermediate the sensor section and the alarm section.

Abstract
A security system includes a plurality of motion sensor units for positioning at desired locations of a building structure, in which each motion sensor unit comprises a motion sensor adapted for detecting motion external to the building structure. The system includes a mobile alarm display unit operatively connected to the plurality of motion sensor units that comprises a plurality of alarm indicators corresponding to the plurality of motion sensor units. Each alarm indicator is operatively linked to a particular one of the plurality 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.

7. A security system comprising:
-
(a) at least one motion sensor unit for attaching to a building structure, the motion sensor unit comprising a motion sensor adapted for detecting motion external to the building structure; (b) an alarm display unit comprising alarm means, and operatively connected to the at least one motion sensor unit whereby detection of motion by the sensor activates the alarm means; and (c) a motion sensor unit bracket for housing the at least one motion sensor unit, the bracket comprising; (i) a first section having an inner side and an outer side, and a first section opening shaped and sized to receive the at least one motion sensor unit; (ii) a second section pivotally connected to the first section, and having a countersunk opening having a shape and size complementary to the first section opening, whereby the bracket is moveable from an open position wherein the inner side of the first section is exposed and the first section opening can receive the sensor unit, to a closed position wherein the second section is pivoted to cover the inner surface of the first section whereby the sensor unit is contained within the bracket; and (iii) attachment means for attaching the bracket to the building structure. - View Dependent Claims (8)

9. A security system comprising:
-
(a) a plurality of motion sensor units for positioning at desired locations of a building structure, wherein each motion sensor unit comprises a motion sensor adapted for detecting motion external to the building structure, and a shield section adapted for preventing the motion sensor from detecting motion internal to the building structure; (b) a mobile alarm display unit operatively connected to the plurality of motion sensor units, and comprising a plurality of alarm indicators corresponding to the plurality of motion sensor units, wherein each alarm indicator is operatively linked to a particular one of the plurality of the motion sensor units and detection of motion by the particular motion sensor unit activates said corresponding alarm indicator linked to the particular motion sensor unit; and (c) wherein each of the plurality of motion sensor units comprises; (i) a sensor section comprising the motion sensor, the sensor section having an inner surface and an outer surface, and wherein the motion sensor comprises a tomographic motion detection sensor that can detect motion through obstructions whereby the sensor can detect motion external to the building structure when the motion sensor unit is positioned within an interior of the building structure, wherein the shield section is adjacent to the inner surface of the sensor section and comprises shielding material providing an electromagnetic barrier to the sensor blocking the sensor from detecting motion through the shield section, whereby the sensor does not detect motion occurring internally of the building structure when the sensor is positioned with the shield section facing the interior of the building structure; and (ii) an alarm section having a sensor alarm indicator that activates upon the motion sensor detecting motion, the shield section positioned intermediate the sensor section and the alarm section. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
