FB-Sentry and the WD310 is a complete web based tracking package for your non-powered assets.

Monitor your assets location and ambient temperature even without power. This small self contained device monitors your assets location with GPS and supports location with Cellular Tri-location using cellular tower information when GPS signal is not available.

The rechargeable 5000 mAh lithium battery provides for long term reporting even over long lengths of time, up to 24 months. This device, once activated, can not be tampered with and turned off mechanically. However, the owner has complete control using over the air technologies, preventing disabling.

View your assets location and get directions to your asset on the website. The secure website is password protected and can view all activated assets on a single page. Drill down and get individual asset information.

Cellular Tri-location

If GPS signal is unavailable (for instance if asset is in metal building), the Faria Beede WD310 will use cellular tower information for a low-precision location. Accuracy is not possible, but reliable, general location information is available. Precision within ½ mile is about average at this time, but location within 50-300 yards is possible.
