Appendix I: PIR Detection Zone
The figure 7 shows the detection range in different
detection angle. 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 angle (
β
). The advantage of this design is to
avoid empty pictures and get available pictures.
