The system is designed to allow unattended operation of equipment and transmission of fault alarms as well as status reports on demand.

The system power consumption is sufficiently low (typically less than 0.5 watt) that it can be powered by solar, battery or other low voltage, low capacity DC supplies. AC powered versions are also available.

Future developments will include PC and PDA Versions as well as expanded capacity versions for monitoring and controlling larger installations. GPS versions are planned for remote tracking of moving vehicles and equipment. GPRS will eventually be used for faster data transfer (no SMS latency). Even lower power consumption versions will also become available.
