Smart Police Force, Mission in Action: See How a Public Security Bureau in Taiyuan Is Setting a New Benchmark for Smart Policing with Hishico’s Five Major Systems!
Foreword:
Amid the wave of digital transformation, public security agencies are not only guardians of public safety but also pioneers in the application of technology. To further enhance police efficiency, optimize command and dispatch mechanisms, and strengthen internal collaborative capabilities, a public security bureau in Taiyuan has completed a smart upgrade of its bureau-wide audio-visual system.
This upgrade has moved beyond the previous situation where individual systems operated in isolation, instead comprehensively adopting Hishico all-scenario solutions. From the command center to conference rooms, and from offices to public areas in hallways, the deep integration of five core modules—professional sound reinforcement systems, intelligent central control systems, distributed systems, digital conferencing systems, and public address systems—has established a new modern police command ecosystem for the bureau characterized by “clear audio, effective coordination, clear visibility, and effective control.”
I.Command with Poise: Distributed Systems Build the “Most Powerful Brain”
For public security agencies, the command center serves as the “nerve center” that handles all types of police incidents and issues operational orders. Traditional audio-visual systems often face challenges such as signal transmission delays, cumbersome multi-device operation, and difficulties in information sharing.
In this project, Hishico distributed system has become the “intelligent core” of the entire command center.
It has achieved full integration of massive amounts of signals. Previously, commanders had to simultaneously monitor surveillance screens, computer data, and map locations, making switching between multiple screens cumbersome. Now, through Hishico distributed visualization and control system, everything from operational data on the public security intranet to real-time footage captured by hall cameras—and even signals from remote video conferences—can be transmitted over a gigabit network with no loss of quality, at low bitrates, and in high definition. All signal sources are clearly displayed on the touchscreen, allowing commanders to simply drag and drop any signal to quickly bring it onto the screen.
II. One-Touch Control: The Smart Central Control System Acts as a “Thoughtful Butler”
The more equipment there is, the more complex the operations become, and the greater the likelihood of errors. To free operators from the burden of managing numerous equipment remote controls, Hishico intelligent central control system has taken on the role of “master controller.”
Hishico network-programmable central control hosts have been deployed in the Public Security Bureau’s conference rooms and multipurpose halls. Acting as a versatile “interpreter,” the system connects all equipment—including lighting, air conditioning, large screens, cameras, and audio processors—via protocols such as RS232, IR, and TCP/IP.
This enables one-click scene switching. Preparation time before meetings has been reduced from the original 10 minutes to “instant transformation with a single click.” For example, when conducting a case analysis, the operator simply taps “Analysis Mode” on a tablet. The lights automatically dim, the large screen turns on, the distributed system retrieves relevant maps and video feeds, and the public address system switches to high-definition mode. When switching to a video conference, tapping “Conference Mode” automatically sets the equipment to the preset conference configuration—the entire process flows seamlessly.
III. Hearing from All Directions: A Professional Sound Reinforcement System Creates a “Crystal-Clear, Resonant Sound”
In venues such as conference rooms and lecture halls, sound quality directly determines the efficiency and formality of meetings. Tailored to the acoustic requirements of various spaces within the Public Security Bureau, Hishico professional sound reinforcement system demonstrates exceptional expertise.
In the command center, background noise is complex and foot traffic is frequent. Hishico employs a digital audio processor with intelligent feedback suppression technology, effectively eliminating potential feedback between microphones and speakers to ensure that commands are not interrupted by piercing noise during emergencies.
In large conference rooms, through precise sound field design and the use of loudspeakers with high sensitivity and low distortion, Hishico ensures that participants—whether seated in the front row or the back row—can hear speech with the same clarity and authenticity, ensuring that no detail is overlooked during case analysis.
IV. High-Efficiency Chambers of Commerce: Digital Conference Systems Enable “Precise Decision-Making”
Designed as a digital conferencing system for daily meetings, this series of conference microphones is specifically tailored for the high-end conference market. Featuring a short boom, high-sensitivity design, and a sleek, elegant appearance, the microphone’s capsule incorporates rubber shock-absorbing material to minimize the impact of table surface noise on sound pickup. Additionally, it can be configured according to the venue’s requirements.
When paired with a camera and configured via the conference control unit or PC software, the system supports automatic camera tracking. When used with the control unit, it supports First-In-First-Out (FIFO), Last-In-First-Out (LIFO), restricted mode, chairman-authorized mode, and free discussion mode. Microphone roles can be customized and changed via the control unit, allowing seamless switching between delegate, chairman, and VIP modes for greater flexibility and to meet high-end requirements; A unique and innovative self-test function, when used with the software, automatically performs button tests, simplifying pre-meeting preparation and ensuring more reliable operation during the meeting; additionally, the microphone supports dual backup for both digital and analog audio.
V. Direct Communication: The Public Address System Strengthens the “Public Safety Network”
As a system-wide public address system, Hishico has also incorporated smart features into it.
The system supports IP-based zoning. Office building hallways, lobbies, outdoor areas, and other spaces are divided into separate broadcast zones. During normal operations, soothing background music can be played to help alleviate the stress of police officers’ demanding work; when announcements are needed, administrators can use the microphone to deliver precise “point-to-point” announcements or set up timed chimes in advance for unattended operation.
Most crucial is its emergency linkage function. During fire emergencies or major police incident drills, the public address system can be linked to fire alarm signals. In the event of an emergency, the system automatically switches to emergency broadcast mode, overriding volume settings to broadcast evacuation instructions with the highest priority, ensuring the safety of all personnel.
VI. Conclusion: Integrating Digital and Intelligent Technologies to Safeguard Local Security
From “rule by man” to “rule by data,” and from “working in silos” to “integrated intelligence,” the collaboration between a public security bureau in Taiyuan and Hishico represents not only an upgrade of hardware equipment but also a comprehensive transformation of policing models.
Professional sound reinforcement systems ensure clearer transmission of orders; digital conferencing systems make decision-making processes more rigorous; distributed systems enhance the efficiency of command and dispatch; intelligent central control systems simplify operations and management; and public address systems enable wider dissemination of information.
These five systems function like “invisible warriors” working as a unified whole, silently supporting every police response, every analysis, and every act of protection through the invisible flow of information. The successful implementation of this all-scenario audio-visual solution not only marks a new milestone for the Public Security Bureau’s “Smart Rock” project but also provides a highly valuable “Hishico model” for the development of a modernized policing system within public security agencies.
In the future, the deep integration of technology and policing will continue, and Hishico will remain driven by technological innovation to contribute the power of “voice and wisdom” to the construction of a Safe China!
