Correctional Communication Security
Take control of unauthorized cellular communications in detention facilities.
The Challenge of Modern Correctional Security
Illegal cellular communications within correctional facilities represent a critical threat to public safety and institutional security:
Criminal Coordination
Inmates use unauthorized phones to direct criminal operations outside prison walls—drug trafficking, witness intimidation, and ongoing gang activities.
Extortion Networks
Phone-based extortion schemes originate from within prisons, terrorizing innocent citizens and extracting millions in payments.
Escape Planning
Coordinated escape attempts rely on real-time cellular communication between inmates and outside accomplices.
Continued Criminal Enterprise
Prison walls become meaningless when inmates maintain constant contact with their criminal networks.
Two Approaches. One Complete Solution.
Sentra Intel offers two complementary technologies that can be deployed independently or together for maximum effectiveness.
IMSI-TRACK PRO
See Every Device. Know Every Identity.
Complete visibility into cellular activity within your facility. Every phone that powers on, every SIM that connects—identified, geolocated, and logged.
Best For
- Criminal investigations
- Intelligence gathering
- Evidence collection
- Visitor monitoring
RF-JAM ZERO
Total Signal Denial. Zero External Impact.
ML-powered calibration delivers maximum signal denial inside your facility with guaranteed zero spillover outside.
Best For
- High-security facilities
- Complete communication denial
- Regulatory-sensitive environments
- Facilities near residential areas
Feature Comparison
| Feature | IMSI-TRACK PRO | RF-JAM ZERO |
|---|---|---|
| Primary Function | Detection & Identification | Blocking & Denial |
| Approach | Monitor and gather intelligence | Prevent all communication |
| Output | Evidence, patterns, locations | Silent zone, zero signals |
| Phones After Deployment | Still work (but tracked) | Cannot connect |
| Intelligence Value | High (patterns, networks) | None (communication denied) |
| Regulatory Concern | Minimal | Requires spillover control |
| Complementary Use |
Complementary Deployment
Phase 1: IMSI-TRACK PRO
Deploy first to gather intelligence on existing phone usage patterns, identify networks, build evidence for prosecutions.
Phase 2: RF-JAM ZERO
Once intelligence is gathered, deploy jamming to eliminate the threat entirely.
