Are there any potential health issues if the RF wireless units is close to staff (or members of the public/shoppers)
The AC powered SNG acts as the signal receiver and the battery powered door sensor is the RF Transmitter. The sensors send signals only once per minute at max. The transmission lasts on 20msec so this is really really low.
For the US and Australia we use the ISM band of 915MHz and it is all within the FCC regulations.
The technology uses really low power, the RF transmitter is in the sensors which are battery powered and last over a year for the bi-directional or over 4 years for the uni-directional counters.
Tech Details:
R.F.Power rating is 0.0117Watts Conducted (Spread Spectrum) 56.82dBuV/m Pk@3Meters (Low Power Device)
