Cellular phone Detection and Jamming

C-Guard Hammer is a combined cellphone detector and cellular phone jammer designed for cell phone control applications. Built in a single case, the Hammer is a smart cellular phone jamming system that detects cellular activity in a given area. Whenever the cell phone detector identifies an attempt of a cellphone to send or receive information – phone call, text or multimedia messages, it instantly turns on the jamming signal for a few seconds, thereby blocking the detected cellphones. Once the detected cell phones are blocked, the Hammer returns to stand by mode.

The Hammer cellphone detection and jamming system can be operated as a standalone mobile phone detector and jammer or as a system - connected to Netline’s Cellular Detectors MS™ control software. The MS central control system provides the officers in charge with real time audio and visual alerts whenever cell phones are detected and jammed.
Netline’s Cellular Detection MS™ software includes history report with detailed specific transmission events for each Hammer, event description, timestamp and more.

C-Guard Hammer combination of cellular phone detector and jammer is in use by military and defense security units to control cellphone usage:

Military/ defense headquarters and command centers - the Hammers cell phone detectors and jammers are used to prevent eavesdropping via cellular based bugging devices and information leakage via mobile phones. The Hammer cell phone detection and jamming system is installed in sensitive areas in the facility. It alerts officers in charge when an un-permitted cellphone is detected and than immediately jammed, thus discovering its existence while preventing transmission of sensitive information.

Military Detention centers use the Hammer Cell phone Detectors and jammers to detect and block smuggled cell-phones. C-Guard Hammers are installed in all strategic locations of the detention facility. The Hammer cellphone detection and jamming system provides the guards in charge detailed online information, useful for locating and confiscating the detected unauthorized cell phones. The inmates cannot use the cellphone since it is blocked, yet the guard has enough data in order to track it down. The Cellphone Detection MS™ software  used with the Hammers includes history log-file with valuable information assisting in maintaining cell-free zone in the facility.

Using the Hammer cellular phone detectors and jammers, ensures unauthorized cell phones will not be serviceable in areas or facilities where cellphone use is not permitted.

The C-Guard Hammer is a custom made cell phone detection & blocking system, designed to suit different applications and coverage areas, from small meeting rooms and chambers to wide range complex sites. Different RF transmission power levels are available, from very low power for small indoor offices to very high power Hammers, for coverage of large outdoors areas.

C-Guard Hammer cell phone detector and jammer can detect and block all required cellular networks and standards simultaneously: UMTS (3G), low and high GSM, CDMA, TDMA Nextel and more.
