Appendix I: PIR Detection Zone

Fig. 9 shows the detection ranges at different detection
angles. When the detection angle is 35°, the detection range is
50ft (15m). When the detection angle is 52°, the detection range
is 30ft (9m).
The PIR detection angle (α) is just barely larger 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.
