CJAM™ 500
Cellular Jamming Device with Auto Jamming Control

The CJAM™ 500 is an advanced cellular jamming device that utilizes unique and intelligent techniques interfering with the downlink between tower and cell phone. It does not generate interference with the cellular uplink frequencies and does not disrupt communication outside of its coverage area.

The CJAM™ 500 insures a cellular phone communication free environment. It can be used to avoid information being disclosed secretly during meetings, and provide the user with control over communication. The CJAM™ 500 jams the signal silently without the knowledge of the cell phone users in its area.

The CJAM™ 500 comes with range adjustment to increase or decrease the coverage area. You can control the size of area so that only one room is jammed allowing communication to take place outside the room.

The CJAM™ 500 also has a unique Signal Detection Mode. It remains off until a cellular signal is detected then turns on to jam the signal. This unique sleep mode makes it virtually undetectable.

Easily operated and user-friendly the CJAM™ 500 is easy to install and requires no professional knowledge or skill

Some of the features include:

Low output power will not cause harm to human body or medical equipment.
Adjustable jamming coverage fit different environments.
Auto 'On' Function upon detection of Cellular Signal
Easy to install

Attention Law Enforcement Agencies
If you represent a local or state law enforcement agency or bomb squad, you are not allowed to use a jamming device to prevent a bomb from exploding. This has left you and the public in a dangerous situation. The threat of Remote Control Bombs are a fact.
