ABSTRACT:
An arrangement and method for processing signals from infrared intrusion detectors is disclosed which allows the signal to be processed at different amplitude levels to recognize different signal characteristics. This capability to analyse the signal at different values allows further customizing of the system for particular applications and provides information useful in recognizing and dealing with unwanted signal changes. The system also accommodates increasing the effect on certain portions of the signal when considering the net overall effect of the signal. This results in more signal information being available and higher accuracy in detecting actual human intrusions in the monitored space.
