From outdoor and pet-friendly digital motion detectors to analogue motion detectors , the Paradox series of motion detectors combines advanced features and patented technologies to provide a high level of detection and false alarm prevention . Whatever the application , there's a Paradox motion detector that will suit your needs and surpass your expectations .                  Developed for high-security applications , our digital motion detectors perform direct analog to digital conversion of the PIR sensors signal using a powerful , high-speed microprocessor-based digital IC . A software-driven process then converts , amplifies and processes the sensors low-level signal in the digital domain without any analog circuitry (no saturation , no loss of data and no noise). This unique technology provides increased accuracy , reliability and superior false alarm immunity .                                                                                         Our patented Auto Pulse Signal Processing transforms the signal energy to a pulse output to determine if the progression of the detected occurrence corresponds to an alarm condition . Energy from the signals are measured and stored in memory until a minimum level is reached . The processor then rejects signals that do not meet its required specifications for generating an alarm .
