5 PIR Detection Zone
This camera has a new design of PIR and the new
PIR is patented. The new patented PIR's detection
range can reach to 73ft in good environments.
Following picture shows the compared detection
zone between normal PIR and the new patented
PIR.
The PIR detection angle (α) is just smaller than the
field of view (FOV) angle (β). The advantage of this
design is to reduce empty picture rate and capture
most, if not all, motions.
