IMSI and WiFi Catchers can be implemented within a prison/correctional/detention centre to monitor for contraband cell phones, which is allowing criminals to continue their illegal activities whilst incarcerated and serving a criminal sentence.

The system can be deployed permanently within a prison environment with capability to set zones and areas and white list prison staff and black list contraband IMSI’s.

Analytics and mapping can provide intelligence of movement of devices as well as identify where IMSI’s move from device to device/zone to zone.

Mobile and drone based Catchers can also be used.
