The GSM Communicator provides a stable and versatile platform for customers wishing to add remote switching and monitoring functionality to a wide variety of applications.

The GSM Communicator supports both SMS and GPRS communication options and offers multiple input, as well as output peripherals.

The device may be used as a stand-alone unit that interfaces to one, or many cell phones. Alternatively, the Sentry GSM Communicator may be used in conjunction with the Sentry GPRS server infrastructure, offering a full remote management solution that is robust, as well as cost-effective.

The device contains a unique virtual wallet feature that allows credits to be loaded onto the device. When an input pulse is detected, the unit determines if credit is available. If so, the pulse is reproduced on an output port and a credit is deducted.
