The Versa PIR-319 is a professional state-of-the-art motion sensor engineered with the world's best components and materials. Special analog stealth circuitry provides micro controller-grade intruder detection at the lowest cost.
The circuitry includes innovative HighBar processing for false alarm rejection - better than most ASIC-based methods. In addition, the patented PYROFLEXTM IR detection provides much stronger intrusion signals than conventional detectors, so the processor easily tells real intrusions from false alarms.
