3.5 Multiple Walk-through Detectors Site Installation
When installing multiple devices, space the devices at least 50 cm, and also space the device and X-
ray security screening machine larger than 50 cm. This recommended spacing can make the little
metal objects (such as coin) detected. If you install the devices with space smaller than 50 cm, there
might be false alarm. If the spacing needs to be shorten because of limited installation site, you need
to adjust the frequency, lower the security level and sensitivity according to the actual situation;
otherwise, small metal objects might not be detected.
