Appendix I: PIR Detection Zone
Fig. 7 shows Bolymedia’s 4 kinds of
detection range at different detection angles.
This camera is extra long range with 55 degree.
Fig.7 : PIR 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.
