Coverage: For the Bellman Visit 868 system:
The normal coverage between a transmitter and receiver in the Bellman
Visit 868 System is approximately 200 metres with a clear line of sight.
Coverage is reduced if walls and large objects screen off the signals. Any thick walls constructed
of reinforced concrete will greatly affect coverage. The system may also be affected by radio
transmitters such as TV transmitters, computers, mobile phones, etc. This means that a unit may
work perfectly in one part of the room but not at all in another.
For the Bellman Visit System:
The normal coverage between a transmitter and receiver in the Bellman Visit System is approximately
80 metres with a clear line of sight. Coverage is reduced if walls and large objects screen off the signal.
Any thick walls constructed of reinforced concrete will greatly affect coverage.
