Passive signal device detection for prison cell deployment

Products

/ Passive / Monitor : Device Signal Detection

Illicit mobile phones and electronic devices continue to pose a serious risk within custodial environments, enabling organised crime, intimidation, and breaches of prison safety.

Monitor

Device signal detection
Revector’s Detector range has been designed specifically to address this challenge. Building on our proven, authorised active detection capabilities, Revector is now introducing a new passive detection solution that provides continuous monitoring without the need for regulatory authorisation.
The passive Detector can be deployed directly into every cell, utilising existing Power over Ethernet (PoE) infrastructure, significantly reducing installation time and cost. Operating silently in the background, the system monitors for signals emitted by any electronic communication device, including mobile phones and associated peripherals.
System Alerts
When activity is detected, the system alerts prison staff, clearly identifying which cells are generating signals, enabling officers to focus searches and interventions where they are most needed. This targeted approach reduces disruption, saves staff time, and improves operational efficiency while maintaining inmate dignity.
By removing the need for authorisation and complex deployment, Revector’s passive Detector makes scalable, cell-level monitoring achievable across entire facilities. The result is improved intelligence, enhanced safety, and a more controlled custodial environment—without the risks or limitations associated with active techniques.
