Building Police Conference Spaces with Sound, Empowering Efficient Meetings with Intelligence | Hishico Audio-Visual System Installed in the Conference Room of the Wanbailin Public Security Subbureau in Taiyuan
Recently, the conference room at the Wanbailin Public Security Sub-bureau in Taiyuan completed an upgrade of its smart audio-visual system. The complete set of equipment—comprising Hishico professional sound reinforcement system and digital conferencing system—has been officially installed, commissioned, and put into trial operation. Based on the public security sector’s requirements for rigorous, stable, and efficient operations, this project provided a customized, integrated acoustic solution. It lays a solid foundation for audio communication during the branch’s daily work planning, case discussions, remote coordination, and staff training, thereby supporting the steady implementation of smart policing initiatives at the Wanbailin Public Security Branch.
I. Project Background: Pain Points in Traditional Conference Management Drive the Need for Smart Space Upgrades
As the central hub for maintaining public order and stability, safeguarding public welfare, and coordinating emergency response within its jurisdiction, the Wanbailin Public Security Subbureau’s conference room is used frequently for daily staff meetings, special analysis sessions, online video conferences, and operational training for frontline police officers. The existing audio equipment, which had been in use for a long time, gradually revealed a number of challenges related to conference operations:
1. The sound distribution in the venue is uneven; audio from seats in the corners is unclear, and feedback, echoes, and background noise frequently interfere with speeches;
2. Management of outdated microphones is disorganized; during group discussions, voices become muddled, making it impossible to manage speaking privileges in an orderly manner;
3. Equipment compatibility is poor; when connecting to remote video conferences or online command and control links, stuttering and audio dropouts frequently occur, resulting in insufficient stability during emergency coordination scenarios;
4. Equipment operation is cumbersome; debugging is difficult for non-professionals, and preparing for impromptu meetings is time-consuming.
To effectively improve the efficiency of conveying information at police meetings and ensure that instructions are issued clearly and accurately, the branch bureau conducted extensive research and comparisons of audio-visual brands in the industry. Taking into account the stringent requirements for high stability, high confidentiality, and strong resistance to interference in government facilities, it ultimately selected Hishico—a company with many years of experience in the government and enterprise audio-visual sector—to develop a customized, comprehensive digital audio-visual solution for its conference rooms.
II. Implementation of the Plan: Synergy Between Two Systems to Create a High-Quality Audio Environment for Conferences
This project focuses on establishing two core components: a digital hand-in-hand conference system and a professional sound reinforcement system. These are complemented by supporting equipment such as DSP digital audio processors, intelligent feedback suppressors, professional power amplifiers, and high-fidelity conference speakers, optimizing the acoustic environment across the entire chain—from front-end sound pickup and mid-end processing to back-end sound reinforcement.
(1) Digital Conference System: Orderly Management to Ensure a Structured Speaking Order
Serving as the central hub for conference proceedings, the Hishico Hand-in-Hand Digital Conference System employs a fully digital wired transmission architecture with exceptional resistance to electromagnetic interference, making it well-suited for the complex electrical environments found in public security buildings.
The system features one chairman unit and multiple delegate units. The chairman’s microphone is equipped with a one-touch priority override function, allowing the chairman to control the floor at any time and prevent audio chaos caused by multiple speakers talking simultaneously, ensuring that case discussions and work assignments proceed in an orderly manner. The microphones feature built-in high-sensitivity pickups paired with AI-powered noise-canceling chips that automatically filter out ambient noise—such as air conditioning, keyboard clicks, and the rustling of papers—ensuring clear and crisp audio even at a distance.
(2) Professional Sound Reinforcement System: Provides a uniform sound field and ensures coverage without dead zones throughout the venue
Taking into account the length and width of the conference room, engineers completed acoustic simulations in advance and scientifically arranged professional wall-mounted conference speakers. Paired with high-power professional amplifiers, this setup ensures that sound is evenly distributed throughout the entire venue, with minimal volume differences between the front and back rows, completely resolving the long-standing issues of inaudibility in the back rows and harsh, distorted sound in the front rows.
The system is equipped with adaptive feedback suppression technology that detects feedback frequencies in real time and quickly filters them out, ensuring no grating noise occurs even during extended group discussions or lengthy training sessions. The digital audio processor features three preset modes—standard meetings, remote connections, and training presentations—allowing for one-click switching to adapt to different scenarios without the need for repeated parameter adjustments, making it quick and easy for staff to operate. Ample power reserves ensure that voices sound warm and natural, while instructions are conveyed clearly and forcefully, allowing every work directive to be accurately transmitted during emergency coordination meetings.
III. Project Highlights: Three Core Advantages Tailored to the Essential Needs of Law Enforcement Scenarios
1. Exceptional stability, ensuring zero interruptions during important meetings
The entire system features a primary-backup redundancy design, enabling seamless switching between core devices. During critical meetings—such as major security deployments and emergency incident assessments—the system remains stable throughout, with no disconnections or audio interruptions, firmly ensuring the stability of government meetings.
2. Minimal operational maintenance, reducing daily management costs
The equipment features a high degree of integration, with neat and uncluttered wiring, making daily maintenance simple. It offers one-touch power on/off and one-touch mode switching, so administrative staff do not need specialized knowledge of audio mixing and can become proficient in operating it in a short time.。
3. Strong compatibility, opening up possibilities for future smart applications
The system includes built-in interfaces for central control, video matrix, and paperless conferencing, allowing for future integration with smart central control systems, remote command platforms, and paperless office systems, thereby providing room for expansion to support the branch’s long-term smart office upgrades.
IV. Practical Value: Empowering Policing with Technology to Strengthen the Effectiveness of Grassroots Work
Conference rooms serve as the central hub for the public security bureau to convey information, coordinate deployments, and facilitate collaborative discussions. The implementation of Hishico audio-visual system represents not only an upgrade in hardware but also a significant enhancement in police operational efficiency.
Moving forward, the branch bureau will be able to deploy and communicate the outcomes of various work meetings with greater precision, facilitate smoother cross-departmental online collaboration, and conduct more efficient case analysis and discussions. The clear and crisp acoustic environment will effectively reduce communication losses, enabling faster implementation of police decisions and more accurate transmission of orders. In the future, Hishico will continue to deepen its expertise in audio-visual solutions for the legal, public security, and government sectors. With mature technology, reliable products, and attentive service, we will continue to empower the development of smart policing and modern government administration across the country, creating more high-quality benchmark cases for government and enterprise meetings.
