Appendix I: PIR Detection Zone
Fig.9 shows Bolymedia’s 5 kinds of detection range at
different detection angles. This camera is super long range with 60
degree.
Fig. 9: PIR Detection Zone
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.
