Appendix I: PIR Detection Zone
Fig. 8 shows Bolymedia’s 4 kinds of detection range at
different detection angles. This camera is super long range.
Fig. 8: 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.
