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 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 sensor's signal using a powerfull,high-speed microprocessor-based digital IC.A software-driven process then converts amplifies and processes the sensor's 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 relaibility 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 untill a minimum level is reached.The processor then rejects signals that do not meet its required specifications for the generating an alarm.
