Description

ABSTRACT

PIR motion detectors are perhaps the most frequently used for security device. Passive IR motion detectors are usually designed to provide an indication to an alarm panel in response to detecting IR that is indicative of motion of the object. The alarm panel is responsive to receipt of the breach indication to cause an alarm condition to occur. When a person or motor vehicle enters a monitored area, PIR motion detectors are commonly used in conjunction with indoor or outdoor to turn on a light in response to a person moving in the field of view monitored by the motion detector. A motion detector of an alarm system has a microwave sensor and a passive infrared sensor, and includes signal processing logic for initiating an anti-masking evaluation upon detection of certain conditions. The detector then samples the sensor signals and compares the signals to a series of possible outcomes. Some of the possible outcomes represent the masking conditions, while others represent normal conditions. A match with masking conditions results in an alarm signal being generated.
