The remote monitoring system comprises a signal emitter (10) providing a signal, means for detecting the signal (12), means for transmitting the signal (16) via a global specification for mobile telephones (GSM) network, and remote means (18, 20) for receiving for the transmitted signal. The signal emitter may be a PIR or other intruder or fire sensor. Alternatively, the signal emitter may be a meter reading module, eg using a radio camera, which transmits the meter reading to a remote station. In another arrangement the GSM network may be used to transmit a control signal, eg to the heating system of a building.
