PIR Detection Zone
Appendix I: PIR Detection Zone
The figure4 shows the detection range in different detection angle. When the detection
angle is 35°,the detection range is 50ft. When the detection angle is 52°,the detection range is
30ft.
Figure 4
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.
Figure 5
SG560K-8M has a new design of PIR and this new PIR is patented. The new patented PIR’s
detection range can reach to 25m. The figure 6 shows the compared detection zone between
