The Device Health reports allow you to keep an eye on the functioning of Zonar devices for your fleet. Each report on this page shows the history of recorded events from one of several Zonar device types, providing critical information each time.

Your company may not use some of the equipment these reports are designed for. Those reports will display zero results.

Reports include:

Device Overview: For a quick look at all devices in your fleet and see which ones need attention.
TCU Phone Homes: For Zonar telematics control units (TCUs) such as the V4 or LD TCU.
Tablet Phone Homes: For Samsung TabActive tablets.
