14 Access Detection Range
The detection range may be influenced by the surroundings at the installation location (indoor or
outdoor). If metal is close by reflection may increase/decrease the detection range.
It may also vary between the different used devices (mobile phones). I.e. some devices have a
longer/shorter range than others because of different antenna designs and where and how they
are placed (e.g. held in the hand or placed in the pocket etc.).
The system has some advanced and unique features to make individual adjustments of the
detection range. Both the transmitted power (TX) and received signal power (RX) can be adjusted
to compensate the installation environment and individual requirements.
If the detection range is not as expected the values can be adjusted up/down to find a suitable set
of values. Please test and adjust as appropriate on location.
