IDM Digital Prison Solution

The overall objective of the digital prison integrates intelligent technologies such as networking, computer, software, and multimedia technologies, transmitting and processing various types of information including voice, text, images, and sensor data through information processing, communication, and biometric technologies, providing critical data and information resources for the public security information system, as well as decision support services.

IDM Digital Prison Functional Modules
Raytrans is a company built on technologies spanning communication service access, transmission, switching, and terminals, providing an integrated solution platform for intelligent prison management. The system's robustness and maintainability meet carrier-grade standards. Based on hardware infrastructure, we provide hardware support and programming interfaces for multiple software platforms and intelligent analysis tools.
A digital prison is not merely a security system + OA office system gradually adopting new technologies; it is also a command & dispatch surveillance system and decision support system that integrates multiple information sources. Our system divides the diverse prison management tasks into five major centers:
Command Center: Focused on the daily work and office operations of prison guards and prison staff;
Surveillance Center: Focused on monitoring and managing inmate activity areas;
Alarm Center: Monitors various violations and critical events, automatically generating alarm signals;
Emergency Center: Stores emergency response procedures, automated processing, and related drills and training;
Rehabilitation Center: Records inmate personal information, legal aid, psychological counseling, including labor reform and educational reform content;

System Features
Our system is a hardware-based command and surveillance system with expansion interfaces reserved for future software development. It features the following:

1. Full fiber-optic cabling with high bandwidth, strong confidentiality, and excellent scalability. Key sections adopt carrier-grade ring network protection, dual-network protection, and dual-system protection schemes. Multiple communication technologies including channel networking and IP routing are employed to ensure system robustness.
2. Integration of legacy audio intercom and video surveillance into the new multimedia digital prison system. The surveillance console enables audio/video monitoring of cells and prison areas; visual intercom with offices and guard posts; multimedia terminal communication (voice, image, text) with mobile sentry posts and management staff; and GPS positioning with audio/video intercom for vehicles leaving the facility.
3. Multi-console operation: during peak hours, multiple consoles work collaboratively according to management authority; during low workload periods, the functions of multiple consoles can be consolidated into a single workstation.
4. A wide variety of access terminals, including telephones, SD/HD surveillance cameras, video intercom terminals, perimeter alarm terminals, access control, biometric systems, positioning systems, trunked radio, vehicle-mounted terminals, mobile multimedia terminals, and prison all-in-one cards.
5. The recording system (audio/video) is a key and challenging component of the digital prison, requiring numerous recording points, long retention periods, frequent retrieval, and diverse associated materials (e.g., personnel files, movement records). We employ multiple servers with detailed categorization, and critical content is recorded simultaneously on dual servers.
6. Interoperability with wireless trunked systems; desktop wired intercom terminals can connect to 2 trunked channels simultaneously.
7. Perimeter alarm and access control: the system features alarm-linked processing. When an alarm occurs, the system first locks the alarm location on the electronic map, then outputs the video and audio surveillance information from that location to the relevant consoles, reconfigures the corresponding access control settings, initiates the appropriate emergency response plan with manual intervention, and records all alarm-related audio, video, control operations, and personnel location information in a high-priority event.
8. (Extended) Positioning management for inmates, with real-time ID verification using biometric information (e.g., facial features, fingerprints). The ID number enables personnel positioning, and based on the assigned activity areas and time periods in the database, the system can automatically assess relevant information and generate real-time alarms for violations. The ID number also allows instant retrieval of currently available video sources covering the individual. The ID number can be cross-checked with the inmate management all-in-one card system. Location records associated with ID numbers require long-term storage for correlation with audio, video, and other information. Electronic handcuffs.
9. Provides a communication channel (hotline) between inmates and their relatives, with recording and retrieval capabilities. Recording file naming offers multiple preset schemes for easy retrieval.
10. A comprehensive information dissemination system with multiple distribution channels, such as audio broadcasting, large-screen display, video conferencing, as well as SMS and email. The dissemination system supports both real-time and scheduled broadcasting.
11. Emergency response plan system: various emergency plans are pre-stored. When management personnel activate the corresponding plan button, the system sequentially initiates broadcasts/multicasts, first sending text and display messages, then audio broadcasts, and finally telephone calls prioritized by hierarchy.
