The C-Guard Hammer Netline’s combined cell phone detection and jamming system is designed for control of cellular activity in prisons and high security facilities.

As a comprehensive solution, when the Hammer detects cellular activity, it jams the frequency momentarily thus blocking the transmission and then reverts to standby mode until the next event. The hammer immediately reports an alert to the central control computer.
