One is a physical method, i.e., by dividing the original technique zone Fresnel lens detection area is divided into several small pieces, small animals can not occupy more than two areas, it can be set only when the alarm signal in the detector when two or more areas occupied by the detector was triggered, in order to reduce false alarms caused due to the small pet walking situation.

The second way is to use the detection signal of the digital processing and analysis methods, pet detection signal detector is mainly for data acquisition, and then analyze the signal period, the amplitude, polarity. These factors reflect the specific shape of the object to move, size, speed, size of pyroelectric infrared energy, and a displacement per unit of time and other characteristics. Data will be collected microprocessor detectors were analyzed and compared, which determine the signal source is a person or small animals.
