Abstract

The present subject matter is directed to an apparatus and methodology for monitoring for the occurrence of use of unauthorized telecommunications equipment within a designated area. The present subject matter has particular utility to the corrections environment in that it discloses a methodology for detecting and reporting the unauthorized operation of cellular telephones within a corrections facility. The present technology may be used advantageously in combination with inmate telephone systems to transmit information to appropriate personnel in the form of email messages and/or voice communications by way of telephone local or corrections facility external telephone lines. The present technology also provides for recordation and storage of time, date and location information for detected events.

2. The cellular telephone detection system as in claim 1, wherein the notification messages comprise an identification of each detected cellular telephone transmission within its respective predetermined zone within the facility, the date and time of transmission detection, and location information identifying the respective predetermined zone within the facility in which each cellular telephone transmission was detected.

3. The cellular telephone detection system as in claim 2, wherein said location information is supplied based on data stored in said interface device.

4. The cellular telephone detection system as in claim 2, wherein said location information is supplied based on data stored in said telephone system.

5. The cellular telephone detection system as in claim 1, wherein the notification messages are relayed to authorized personnel of the operation of unauthorized cellular telephone usage within the predetermined zone within the facility.

6. The cellular telephone detection system as in claim 1, wherein said telephone system is configured to generate one or more notification messages in a format selected from a group comprising of email messages, telephonic voice messages, and information records.

7. The cellular telephone detection system of claim 1, wherein at least one of said cellular transmission detectors is positioned within the facility such that its respective detection zones do not overlap with a detection zone of any other of the plurality of cellular telephone transmission detectors.

8. A computer-readable device having instructions stored thereon, execution of which, by a computing device, causes the computing device to perform operations to monitor one or more areas within a facility for unauthorized cellular telephone transmissions, the operations comprising:

providing a plurality of cellular telephone transmission detectors, with each detector configured to produce a detection signal upon detection of cellular telephone transmissions;
