One-Stop, Single Platform
The modular architecture of SENTRY allows for rapid customization and the capability to include separate sensor components and radios. These elements connect and work together to make the SENTRY a robust and flexible, one-stop hardware platform.
Meets the Most Demanding GPS Tracking, Sensing and Control Needs
SENTRY offers ruggedized packaging and broad operating temperature ranges for use in harsh environments. These features plus standardized mounting options, extended battery options, and external sensor capabilities, make SENTRY the right device for even the most demanding GPS tracking and sensing needs.
Secure and Tamper Resistant
For security applications such as ContainerSafe, situations where a "covert" install is required or for applications that require SENTRY to operate independent of the driver, maintenance, or delivery personnel, the unit can be configured to alarm immediately if tampering or unauthorized motion occurs.
Reports from Virtually Any Location on the Globe
SENTRY's modular architecture enables the use of the most cost-effective reporting path for your application needs and will report from virtually any location on the globe using one, or a combination, of the following: Mesh, WiFi, SMS, GSM/GPRS, CDMA and LEO Satellite.
Configured to Meet Your Business Needs
To meet your application needs, SENTRY can be designed to dynamically support customized business rules as well as dispatch alarm and notification messages specific to your operations. Users can also define reporting frequency as often as every 30 seconds or as infrequently as required.
Keeps Thinking, Even When Not Connected
SENTRY is equipped with 16MB of internal memory and expandable up to 8GB, depending on what you need. This, plus onboard logic, enables SENTRY to continue storing information from the connected asset and forward all the data once the wireless connectivity is restored.
FlightSafe™
SENTRY is the only M2M hardware device on the market capable of operation for land, sea, and air. Equipped with a patent-pending feature, called FlightSafe, SENTRY is able to detect when in range of an aircraft to dynamically adjust its reporting mode. This allows our customers to choose one hardware platform no matter where or how the asset travels.
