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.
