JamAlert, a device designed to detect when cellular frequencies are being jammed, has been released by Digital Monitoring Products (DMP). JamAlert instantly notifies the control panel when cellular communication is being compromised, empowering security professionals to stay ahead of the threat. Production and distribution of cellular jammers is on the rise in the U.S. These illegal devices are being used to defeat alarm system communications, allowing thieves to enter compromised facilities undetected. When jammed, cellular alarm signals never make it to the monitoring center and no authorities are dispatched. By detecting cellular jamming on multiple frequencies, JamAlert offers a way to mitigate potential losses.
