"Contraband communication devices are a growing problem for correctional facilities as they undermine the objective to keep inmates separated from the outside world and the crime community," said Brian Rich, President at Senstar. "Gallium-PDS was developed specifically for the specialized complex mixed RF environments of correctional facilities. It co-exists with the numerous on-site friendly communication devices, and can pinpoint use of illegal ones to within one inmate cell.”
Gallium-PDS is built around sophisticated, yet affordable signal processors that cover a wide radio frequency (RF) range and have the capability to scan and focus on individual transmitters, thus ignoring irrelevant legal transmitters within and outside the facility. A network of sensors and processors correlates received cellular signals and generates a map of the transmitting devices, with an accuracy of a few meters (approximately 10 feet). The results are superimposed on a building floorplan which enables a response force to quickly and accurately act on the violation.
