Sentinel Pro


Sentinel Pro alerts fleet managers of a driver’s cell phone use while driving, speeding, reckless driving, driving outside of an employer-approved radius or driving during unauthorized hours. Sentinel Pro reports a driver to the fleet manager in real-time if the driver ignores one of the device’s audio alerts.

Sentinel Pro has a tracking function so that fleet managers can monitor cell phone activity episodes and track progress by the driver. Hours of service are also tracked so that Sentinel Pro works as a logging device. If a fleet manager needs to get in touch with the driver, Sentinel Pro prompts the driver to safely pull over and turn on his or her phone.

Type of Technology:

Vehicle-based driver monitoring device.

Target Audience:

Commercial vehicle drivers

Manufacturer and Country of Origin:

VRM Telematics, LLC MS (USA)


Can be ordered from manufacturer.

Means of Activation:

The device is plugged into a vehicle’s diagnostic computer port which is situated under the dashboard. Similar to a seat belt chime, Sentinel Pro reminds drivers to either turn off their phones or set them in airplane mode. Since it is vehicle-based, Sentinel Pro discourages the driver from being distracted by any cell phone use in the car whether the phone is being used by the driver or passenger.


Sentinel Pro does not restrict cell phone use. Instead, it is intended to remind the driver to turn off the phone and it alerts fleet managers if the driver is using the phone while driving. Cell phone use is not reported when the vehicle is turned off or it is idling.


If Sentinel Pro is disconnected, an alert is sent to the fleet manager.
