L1-01D.22 – Analytics

Some detectors are designed to use analysis to “see” the body dimensions of people and differentiate from backgrounds and...

L1-01D.20 – Temperature Compensation

When the person to background contrast smaller – the output pulses from the PIR element will become smaller. Most PIR detectors will suffer a decrease in the coverage pattern as a result. Some detectors compensates at ambient temperatures below body temperature....

L1-01D.19 – Background Contrast

When background or ambient temperature approaches that of a human being (approximately 88F), the lack of contrast can make detection...

L1-01D.18 – Multi-Level Signal Processing

Introduced to reduce false alarms Second Threshold set based on research on walk tests Signals processed at slower rate between 1st & 2nd thresholds Signals processed at normal rate above 2nd...
