Daylight and thermal sensors allow the unit to automatically compensate for varying climate conditions, whilst the sensitivity of the pyro can be adjusted by changing the AB filtering settings which determine whether an alarm is generated depending on whether one (A or B) or both (A and B) infrared beams is crossed. Genesis 1 uses a sophisticated dual element pyro sensor combined with a powerful microprocessor which uses complex algorithms to determine the validity of detection events. This minimises nuisance alarms and increases detection accuracy. The Genesis 1 3020 variant features two dual element pyro sensors and mirror optics to provide a much larger detection range without sacrificing accuracy. Genesis 1 has four built-in methods of detecting a tamper alert: the shock sensor detects physical attacks, the anti-masking sensor allows the unit to detect when the lens has been covered, the 3-axis inertia sensor detects movement of the unit, and there is a switch that detects when the front and back of the unit have been separated. The anti-tamper sensors remain active event when the unit is disarmed. All Genesis 1 detectors are housed in a durable polycarbonate housing, are IP66 weather rated and are EN50131-1 Grade 2 compliant.
