ET Environmentally Tolerant Infrared Detector

ET uses split offset optics with dual channel processing from twin dual element sensors. Output from each channel is monitored by a dedicated high-speed microprocessor which compares the signals for mass, speed, timing and direction, so ET can distinguish between human targets and other random sources of infrared energy.



ET will reliably tolerate hostile environments while still exhibiting razor sharp response to intrusion. ET will also tolerate small animals and rodents without false alarms, but is not recommended as a pet exclusion sensor.



Temperature compensation is microprocessor auto sensitivity adjust. Multi-facet 120 degree white filtered lens with 14 metre adjustable range.
