SignalSecure CDS
SignalSecure Contraband Disconnect Service (CDS) is an innovative solution to combat the use of illegal cellphones and unauthorized wireless devices within prisons and secured facilities. These contraband devices are used to coordinate criminal activity, contraband trade, escape attempts, corporate espionage, and external communications that threaten public safety. With SignalSecure CDS, we give prisons and other high-security sites a fast, FCC-compliant way to find and shut down illegal phones—protecting people, operations, and sensitive information without interrupting authorized communications.
ADRESSING ONGOING THREATS
- Constant Interdiction: Detects, discovers, locations, confirms, and disconnects unauthorized wireless devices in real time, in full alignment with FCC 47 C.F.R. § 20.23.
- Pinpoint Accuracy: Optional Wi-Fi hotspot detection and handheld “walk-down” tools trace rogue devices.
- Zero Collateral Impact: Proprietary algorithms and scan techniques develop a target list of contraband phones while leaving approved networks untouched.
