Recently, the Ministry of Public Security disclosed a set of key data at a press conference: Public security organs across the country have equipped over 1.3 million law enforcement recorders for frontline police officers, achieving full audio and video recording of on-site law enforcement, and promoting police officers to "get used to enforcing the law under the camera". This measure is a core link for public security organs to implement the full-process record mechanism for law enforcement, aiming to standardize law enforcement behavior through technological means and safeguard the lawful performance of duties by police officers as well as the legitimate rights and interests of the public.
I. Technological Upgrade: From "Recording Tool" to "Intelligent Hub"
With the in-depth application of technologies such as AI, 5G, and Beidou positioning, body cameras are undergoing an intelligent transformation
-AI intelligent early warning: Some new devices are equipped with AI algorithm chips, which can identify abnormal scenarios such as violent conflicts and dangerous equipment in real time, automatically trigger voice reminders, and assist law enforcement officers in predicting risks. The AI voice transcription function can also convert on-site conversations into structured text and automatically generate initial drafts of law enforcement documents, with efficiency increased by over 80%.
-5G Real-time transmission: Supports 5G+4G dual-mode communication. 1080P high-definition video can be transmitted back to the command center within seconds. Even in remote areas, stable transmission can be maintained, achieving efficient linkage between the "site" and the command center.
- Beidou precise positioning: In environments without public networks (such as tunnels and deep mountains), location information is transmitted back within seconds through the Beidou short message function. Combined with inertial navigation and UWB technology, the positioning error is ≤0.5 meters per minute, providing crucial support for emergency rescue.
- Hardcore protection performance: Military-grade protection design (IP67/IP68 grade), supporting 3-meter drop resistance and underwater video recording; The 170° wide-angle lens combined with infrared night vision enables all-weather and blind-spot-free evidence collection.
II. Institutional Innovation: Full-process Documentation Reshapes the Law enforcement Ecosystem
The popularization of body cameras and institutional innovation have formed a synergy effect:
1. The entire law enforcement process is traceable
On-site law enforcement: Police officers must wear recorders properly to record the entire process of response, punishment, and inspection, forming a "black box" -style restoration capability.
- Case handling center management: A total of 3,266 law enforcement case handling management centers have been established across the country, achieving full coverage at both the municipal and county levels. The 24-hour all-round surveillance and synchronous audio and video recording of interrogations within the center effectively restrain law enforcement behavior.
2. Optimize services through source control
The "Three On-the-spot" system: When the public comes to report a case, they should register on the spot, accept evidence, issue a receipt and inform the public of the way to inquire, to prevent shirking and delaying.
The convenient measure of "reporting by code" : In places like Liaoning and Zhejiang, quick reporting by scanning codes has been implemented, replacing handwritten registration and enhancing the experience of the public.
3. Cross-departmental collaborative efficiency enhancement
- Management of involved assets: The Xiamen Public Security Bureau has developed a "safe deposit box for involved assets", which tracks the whereabouts of each asset through QR codes. Since its operation, the center has standardized the handling of over 1.2 million cases, saving 150,000 hours of case-handling time.
III.Effectiveness and Prospect: Dual Enhancement of Safety and Efficiency
- Zero safety incidents: After the implementation of the "integrated" operation mechanism by the law enforcement and Case handling management Center, many places have achieved "zero" major law enforcement safety incidents, and the case handling efficiency in Jiangsu and Chongqing has increased by more than 30%.
The credibility of the rule of law has been enhanced: In 2024, the number of cases supervised by procuratorial organs across the country decreased by 71% year-on-year, and the rates of non-approval for arrest and non-prosecution both dropped by approximately 6%, reflecting a significant improvement in the standardization of law enforcement at the source.
In the future, body cameras will develop towards greater intelligence (such as AI facial comparison), greater integration (multi-system linkage), and greater portability, continuously injecting technological impetus into the construction of a law-based China.
