Mobile Intelligence Collection System

Intelligent mobiles management system for prisons

Modern prisons face multifaceted challenges, among which unauthorized mobile communication poses significant security threats. Addressing this, the Prison Guard system offers a comprehensive solution, designed to monitor, detect, and manage unauthorized cellular activity within prison boundaries.

Customizable to fit the unique specifications of each facility, the Prison Guard system is tailored to both the size of the prison and its inmate population. Its primary objective: is to deny all unauthorized mobile communications within its coverage area.

Equipped with advanced technology, the system allows prison authorities to:

  • Identify & Control: Pinpoint and manage GSM, UMTS, and LTE cellular devices within the prison.
  • Alert & Deny: Detect predefined targets and immediately halt their mobile services, ensuring the prevention of unauthorized communications.
  • Exclusive Communication: Provide a secure, private channel for Voice, SMS (2G), and Mobile Broadband (4G) exclusively for prison authorities, integrated seamlessly with the prison’s PABX and Intranet system.
  • High-Speed Data Transfer: Its advanced infrastructure supports faster data transfers and video streaming capabilities, outstripping traditional systems in performance.


Configurations Available:
The Prison Guard system can be adapted to various configurations to suit different environments:

  • Tactical Case
  • Rack Mounted
  • Fixed Installation
  • Vehicle Mounted


  • Identity Tracking: Captures unique identifiers of all registered cellular devices within the prison perimeter.
  • Multiband Detection: Rapidly detects activities across multiple frequency bands & technologies, including 2G, 3G, 4G, 5G, and optional Wi-Fi.
  • Pinpoint Accuracy: Leveraging the Cellular Device Locator (CDL), authorities can determine the exact location of a device or user with up to 1-meter accuracy.
  • Automated Alerts: Generates automatic notifications upon the detection of predefined targets or any new mobile device within the prison.
  • Advanced Analytics: Equipped with data import/export capabilities and integration options for big data analysis tools, providing valuable intelligence insights.
  • Private Secure Network: Establishes a dedicated cellular network, separate from the public network, exclusively for law enforcement use.
