Is it possible to receive a signal via GPRS/3G connection?

Yes, it is. With the help of the IP network the reception of signals according to ContactID or VdS2465 is possible directly with the built-in IP Communicator, without any special receiver unit. It means that the IP connection can be established between the transmitting unit and the central UniAlarm Dispatcher with a suitable GSM/GPRS/3G/4G device.
