Appendix I: PIR Detection Zone
The figure 8 shows the detection range in different detection angle.
When the detection angle is 35°, the detection range is 50 ft(15m).
When the detection angle is 52°, the detection range is 30 ft (9m).
Fig. 8 Different detection range
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.
