Prison Audio and Intercom System Solution

I. System Architecture Design

Multi-level Networking Architecture

• Construction of Three-level System: Establish a three-level system comprising the head control center (Provincial Prison Administration Bureau), sub-control centers (prison command centers), and grassroots terminals (cells, workshops). Support TCP/IP protocol transmission to achieve centralized management of audio and video data. Deploy IP network ceiling speakers, wall-mounted speakers, and weatherproof sound columns at the front end to cover areas such as cells, corridors, and outdoor activity areas.

Intelligent Platform Integration

• Platform Adoption: Utilize the VSMC video management platform or a customized system, integrating functions such as broadcasting, intercom, alarm linkage, and access control. Support integration with the prison security platform to achieve unified dispatching.

II. Core Functional Modules

Intelligent Broadcasting System

• Scheduled Automatic Playback: Preset schedules for rest prompts and educational program playback, achieving high automation.

• Zoned Broadcasting: Divide broadcasting areas by prison area and functional area, supporting independent control or whole-area broadcasting.

• Emergency Broadcasting: Link with the alarm system to automatically insert evacuation instructions in case of emergencies, covering the entire area.

Intercom and Monitoring Functions

• Two-way Intercom: Support full-duplex calls between cell terminals and sub-control centers, supporting multi-party consultations.

• Emergency Call: Equip cells with help terminals for one-button alarm triggering and linkage with monitoring screens.

• Real-time Monitoring: Allow management personnel to remotely listen to sounds in various areas for immediate handling of abnormal situations.

Alarm Linkage Mechanism

• Linkage with Fire and Perimeter Defense Systems: Trigger audible and visual alarms and initiate emergency broadcasting in case of emergencies, supporting remote control of access control systems.

III. Key Technical Advantages

High Reliability

• Data Encryption Transmission: Ensure system stability with data encryption, support for power-off continuation, and redundant backup.

• Embedded System Design: Protect against virus interference with low maintenance costs.

Scalability and Compatibility

• Modular Architecture: Increase terminals or functional modules (such as face recognition intercom) as needed.

• Compatibility: Support mainstream brand devices and integration with GPS positioning and GIS geographic information.

Intelligent Management

• AI Voice Broadcasting: Enhance broadcasting experience with AI voice announcements and automatic background music attenuation.

• Secondary Development API Interface: Adapt to future smart prison upgrades with provided API interfaces.

IV. Typical Application Scenarios

Daily Management

• Schedule playback of educational programs and rest prompts to reduce labor costs.

Emergency Response

• Remotely initiate whole-area broadcasting during emergencies to uniformly issue evacuation instructions.

Security Monitoring

• Link with monitoring systems for synchronized audio and video playback to assist in incident investigation.

V. Solution Value

Safety Assurance

• Early warning through intelligent analysis to reduce safety incidents.

Efficiency Improvement

• Multi-level networking reduces labor input, with AI handling routine events automatically.

Compliance

• Meets requirements of "Prison Construction Standards" and "Smart Prison Technical Specifications."
