2. Radio-frequency interference (RFI) – if you have other devices operating on 868 / 915 / 917
MHz, you might experience communication intermittent. Please re-located your transmitter
or display console to avoid signal intermittent problem.
3. Distance. Path loss occurs naturally with distance. This device is rated to 150m (450 feet)
by line of sight (in interference free environment and without barriers). However, typically
you will get 30m (100 feet) maximum in real life installation, which includes passing through
barriers.
4. Barriers. Radio signal are blocked by metal barriers such as aluminum cladding. Please
align the sensor array and display console to get them in clear line of sight through window
if you have metal cladding.
The table below show a typical level of reduction in signal strength each time the signal passed
through these building materials
Materials Signal strength reduction
Glass (untreated) 10 ~ 20%
Wood 10 ~ 30%
Plasterboard / drywall 20 ~ 40%
Brick 30 ~ 50%
Foil insulation 60 ~ 70%
Concrete wall 80 ~ 90%
Aluminum siding 100%
Metal wall 100%
Remarks: RF signal reduction for reference
