Advanced Prison IMSI Catcher and Phone Signal Directinal Finder

Mobile phones have become one of the most significant security risks inside correctional facilities. Unauthorized communication can facilitate criminal coordination, information leakage, and violations of prison regulations. As correctional institutions continue to strengthen security measures, advanced mobile device detection technologies have become an essential component of prison security systems.

Our High Power IMSI Catcher for Prison is specifically designed for prisons, detention centers, correctional institutions, military facilities, and other high-security environments. The system enables security personnel to detect active mobile devices, identify subscriber information, manage authorized and unauthorized users, and improve operational efficiency through centralized monitoring.

Whether protecting a small detention center or a nationwide prison network, our scalable IMSI Catcher solution provides reliable coverage, flexible deployment, and professional management capabilities.

A Prison IMSI Catcher is a professional mobile subscriber identification system that detects active cellular devices within a designated area by identifying their IMSI (International Mobile Subscriber Identity). Unlike traditional security equipment, an IMSI Catcher provides real-time subscriber identification, allowing correctional authorities to recognize unauthorized mobile devices operating inside prison facilities. The system is widely used by government agencies and correctional institutions where enhanced communication security is required.

Our high-power base stations provide extensive RF coverage suitable for:

• Large prisons
• Multi-building correctional facilities
• High-security detention centers
• Border security compounds
• Government institutions

The number of IMSI Catcher units required depends on the prison's total area, construction materials, and desired coverage. Our engineers provide customized deployment plans for every project.

One of the most valuable features of the system is flexible subscriber management. Administrators can easily configure:

• Authorized staff mobile phones
• Emergency service devices
• Government communication terminals
• Temporary visitor authorization

Unauthorized or suspicious devices can be added to a blacklist for continuous monitoring according to operational policies.

Benefits include:

• Fast authorization management
• Reduced false alarms
• Centralized subscriber database
• Efficient security operations

Each prison is equipped with one dedicated management server. The server provides:

• Real-time IMSI collection
• Device database management
• Event logs
• Alarm management
• Historical records
• User management
• Remote maintenance
• System health monitoring

Customers may purchase the server locally based on our recommended hardware specifications, or we can provide a complete pre-configured server as part of the solution.

Detecting an IMSI is only part of the solution. To locate the physical position of an unauthorized mobile phone, each correctional facility can be equipped with one Portable RF Direction Finder.

This handheld device assists prison officers by:

• Locating hidden mobile phones
• Identifying RF signal direction
• Searching prison cells efficiently
• Reducing inspection time
• Improving operational efficiency
• Supporting routine prison inspections

The Portable RF Direction Finder works together with the IMSI Catcher system to provide both subscriber identification and physical device localization.

A standard deployment typically includes:

• High Power IMSI Catcher Units
• One Central Management Server
• One Portable RF Direction Finder
• Management Software
• Network Equipment
• Installation Guidance
• Technical Support

The architecture is modular and scalable, making it suitable for correctional facilities of different sizes.

Our IMSI Catcher solution is suitable for:

• National Prisons
• Correctional Facilities
• Detention Centers
• High-Security Government Facilities
• Border Control Facilities
• Sensitive Bases
• Law Enforcement Training Centers

Compared with conventional mobile device monitoring systems, our solution offers:

• High-power RF coverage
• Stable long-term operation
• Flexible deployment
• Intelligent blacklist and whitelist management
• Centralized monitoring platform
• Scalable architecture
• Easy maintenance
• Professional engineering support
• Custom software development
• International project experience

Every prison has unique architectural characteristics. Factors affecting deployment include:

• Prison area
• Building height
• Wall materials
• Number of cell blocks
• Required coverage
• Local cellular network environment

Our engineering team performs customized system planning to determine the optimal number of IMSI Catcher units and deployment locations.
