A remote monitoring system for a utility meter 10 comprises a signal emitter 12 providing a signal, means for transmitting the signal 14 via a telecommunications network (eg PSTN or GSM) and remote means 18,20 for receiving the transmitted signal. The signal emitter may comprise a digital camera which views the utility meter and sends the acquired image back to the remote means via the transmitting means 14. The utility meter and camera may be housed in a transparent plastic hood (22, fig.2) and the meter may be illuminated via an LED. Power for the camera and LED may come from a rechargeable battery (28, fig.2) which is charged via a double wound transformer (24, fig.2) surrounding an incoming mains cable (26, fig.2). The signal may be transmitted to the remote location in response to instructions therefrom or may be controlled via a timer. |
