Remote Monitoring 70W High Power Signal Jammer , Water - Proof Cellular Jammer


Cellular Jammer Description:

GW-JB40 with Built-in Directional Antenna, is a High Power Indoor/outdoor Water-proof Cell Phone signal jammer, implementing the most effective and reliable RF jamming technology to prevent the leak of confidential information or unwanted usage of cell phones, Wi-Fi devices and Bluetooth devices.

All weather waterproof design, using professional waterproof enclosure; Integrated remote monitoring system, remote maintenance available via the Internet RJ45 Network Cable. Only interfere downlink frequency of mobile system,without disturbing norrmal working of Base Station; Imported elements, Slow start up design of circuit. These elements can maintain the stable operation condition with high integration,

Perfect self-protection function, when the equipment overheating, over Output power, VSWR alarm, Jammer will automatically turn off the faulty module to avoid Jammer damage;


Once the system is activated, it transmits unique noise signal which creates "Firewall" between the transmitter and its receiver (cell phone and Wi-Fi device). This jammer has passed the strict inspection and gotten the certification from The Ministry of Public Security Safety and Police Electronic Product Quality Inspection Center, Electronic Products Quality Control Center, and The Electromagnetic Leakage Transmission Safety Protection Product Testing Center.

Besides, The Jammer can prevent the leak of confidential information leak via cell phones or unwanted GPS location leak.


Cellular Jammer Application:

To prevent unwanted usage of cell phone and WiFi
To prevent the leak of confidential information
To prevent the leak of GPS location
To prevent the remote-control cell phone bomb
Bomb disposal and vehicle mounting for military complexes.
Filed Operation activity
Special Police Authorities
VIP convoy for security purpose
Control operation


Jammer Monitoring Software Platform Introduction:
1. The Jammer Monitoring Software Platform allows users to monitor and control all Jammers through Internet, and all real-time alarm information feedback to the users immediately. So that users can stay at office to have all information of jammers working status, and adjust the Jammers to suit the operating environment of the installed area, greatly reduce the customer's maintenance workload.

2. The platform enables real-time display of all Jammers' output power, operating temperature, alarm information (including over-temperature alarm, under-power alarms, VSWR alarms, Door open alarms, etc.), and all information is specific to each Channel, real-effective, convenient and quick.

3. This platform also allows you to change the login page photo and upload your own logo by yourself.



Cellular Jammer Advantages:

  1. Seven High Power jamming signal generators inside.
  2. Jamming up to 7 different jamming modules.
  3. High Gains directional Antennas.
