Motion detection
EMDCB contains an integrated passive infrared (PIR) detector that can detect moving ob-
jects based on the temperature difference between the moving object and its environment.
2.5.1
PIR detection characteristics
EMDCB is designed to detect movement within a radius of up to 5 m (16 ft.) when mounted
at a ceiling of 3 m (10 ft.) height. The recommended coverage area for best detection per-
formance is within a radius of 3 m (10 ft).
Figure 5 below shows the PIR detection pattern.
