Site Monitoring and Control Systems

TeleSense systems are used to monitor remote radio and equipment sites.  Applications include monitoring repeater systems, broadcast equipment, wireless ISP installations, paging equipment and solar power infrastructure.  TeleSense is also used for monitoring high-end remotely controlled amateur radio stations.

TeleSense systems are internet enabled or can be connected to Sierra Radio repeater control systems.

These systems provide constant logging from various sensors, web and mobile user interfaces, secure cloud based data storage and a variety of sensor and control modules.
