The product is constructed to military standards and utilizes the highest grade electronics. However, the best technology can experience mechanical and electrical failure.
In light of the critical; early warning role in detection of landslides, washouts and structural health monitoring, EarthSub has a number of levels of “heartbeat” to ensure it’s connectivity and functional state. If a sensor loses contact with a site controller an alarm is triggered. If a site controller loses contact with the server software applications a further alarm is initiated to allow service personnel to check the installation.
To offset any data communications failure, the site controller is capable of triggering an analogue alarm that can be observed by passing maintenance or field personnel.
It is as close to a failsafe early warning system as is possible.
