NDR-PJ900 cellular jammers

These cellular jammers are in constant control by a central administrator that can permit or deny cellular communications. These cellular jammers are connected via a Controller Area Network (CAN) into a local network and managed by a Central Base Station (CBS). The NDR-PJ900 controls every element, from detection, to alerting where and when an individual cell phone is attempting to establish communication, to blocking the calls. 

In order control cellular phone activity in any given area, an established configuration is designed. This is comparable to building a fence. However, instead of placing posts and fencing at a physical border, cell phone jamming hardware is deployed to operate in many (or few) buildings or areas. These cellular jamming units can deny access to a large number of cellular telephones at any given time within a group of separate buildings, or a complex of corridors, conference rooms, numerous small offices and private rooms.

Not a cell phone jammer, the System detects and manually or automatically blocks unauthorized usage of cell phones and/or cell phone activity in designated areas. The cellular detector composition functions as a cellular detection center and works symbiotically with the cellular jamming feature.
