Table 2 People Counter Coverage
The measurements shown in the table are from head to head measurements. Figure 1 Head
to Head Measurement, it is displayed that the actual Field of View (FOV) is larger than the
counting FOV listed in the above table. The target person to be counted must be observed full
body in the camera vision to be counted. Figure 2 FOV Violation, red filled person will not be
detected and tracked by the counting system. While determining the number of devices to be
used in a site, the measurements will be made according to head to head principle. If the
width/height ratio of the counting area is larger than a V-Count device; multiple devices will
be used, as shown in Figure 3 FOV Multiple Devices. Sample installation can be seen in
