6.1 Installation Height
The maximum installation height is 3.5 m and the minimum installation height is h
max
+d+Δd. For
example, when the maximum pedestrian height is 1.8 m, then the minimum installation height is
1.8+0.5+0.035=2.335 m.
6.2 Covered Detection Area
The monitored area refers to the range visible to the device (FOV), which is displayed on the
dashboard. The detection area, which is smaller, refers to the range within the monitored area
where the device can detect changes in the number of people.
The detection area covered by the device is related to the field of view angle of the device, the
installation height and the target height. The length of the detection area is approximately
x=2.300×(H-h
min
) and the width of the detection area is approximately y=1.678 x (H-h
min
).
For example, if the Minimum height of pedestrians is 1.7 m, the detection area corresponding to
each installation height is as follows:
