Micron ET Environmentally Tolerant Infrared Sensor

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. Multifacet

120 degree white filtered lens with 14 metre adjustable range.
