Appendix I: PIR Detection Zone
Fig.6 shows Bolymedia’s 4 kinds of detection range at different
detection angles. This camera is extra long range with 55 degree.
Figure 6: 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.
