SYSTEM AND METHOD FOR INTRUDER DETECTION
First Claim
1. A system for detecting intruders, comprising:
- a transmitter configured to produce an energy beam;
a first receiver configured to detect energy from said beam; and
a processor provided to said first receiver, said processor configured to detect a presence of an intruder by determining when said energy beam is at least partially interrupted, said processor further configured to distinguish between intruders and non-intruders by communicating with an RFID carried by non-intruders.

Abstract
Systems and methods for detecting presence and movement of intruders. Various embodiments of an intruder detection system can be based on, for example, a beam-interrupt detector or a thermal imaging device. The beam-interrupt detection based system can provide functionalities such as counting of intruders crossing a given beam. A plurality of such beams at different heights can also allow distinguishing different-sized intruders. The thermal imaging based detection system can provide functionalities such as tracking movement of intruders. A recording can be triggered by detection of intruder movement, thereby improving the efficiency of recording and reviewing information indicative of presence and movement of intruders in a monitored area. In one embodiment, non-intruders can be distinguished from intruders by querying an RFID tag carried by non-intruders. In one embodiment, non-intruders can be distinguished from intruders by facial recognition.

24. A system for detecting intruders, comprising:
-
a camera configured to produce first and second digital images; an RFID reader configured to read RFID tags within a field of view of said camera; and a processor provided to said camera, said processor configured to examine said first and second digital images to detect a movement of one or more intruders by determining movement of an intruder-sized object in said first and second images, said processor further configured to distinguish between intruders and non-intruders by using said RFID reader to read an RFID tag carried by non-intruders. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)
