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.
