Cellbusters,a developer of cell phone and RF emission detection locating technology, recently announced Zone Protector & Zone Manager Corrections Suite to help users eliminate contraband cell phones. Marion County Detention Center (MCDC) was the first to use the Corrections Suite to enhance safety at a prison. The Zone Protector is a passive frequency detection device capable of detecting cell phone transmission activity. It provides maximum protection for MCDC by continually scanning for cell phone and user selectable RF transmission. The Zone Manager is a centralized software tool that collects information in real time from distributed Zone Protectors located around the correctional facility, and logs the location of contraband cell phones. Based on customer preference, alerts are sent instantly or silently logged. Since MCDC uses a cloud, any new features to the software are automatically and seamlessly integrated.
