Anytime the device is removed and then reinstalled, a notification is sent to you stating the time the device was removed or tampered with, the time it was reinstalled, and it will give you a breakdown of how long it was removed.
It's important to note that the alert is sent when the device is reinstalled and not when it's initially removed. The device can not communicate to our servers if there is no power source to the device.
To find this type of alert at any time, tap on the Notifications icon at the bottom of the app screen and tap on Vehicle.
