Appendix I: PIR Detection Zone
Figure 6 shows Bolymedia’s 4 kinds of detection range at
different detection angles.
Fig.6 Different detection range
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.
