Body won camera is widely used in industries such as public security, procuratorial and judicial departments, emergency management, transportation, electricity, railways, petrochemicals, etc. It is mainly used for law enforcement evidence collection, safety inspections, emergency event recording and other scenarios. It can digitally record dynamic and static on-site situations during law enforcement, making it convenient for public security officers to use it in various environments.

With the strengthening of law enforcement standardization and safety production supervision in China, various industries have also introduced relevant policies to drive industry development, resulting in a continuous growth in demand for law enforcement recorders. For example, the Ministry of Public Security requires national public security organs to promote the recording of the entire law enforcement process to ensure transparency in law enforcement, the Ministry of Emergency Management requires industries such as petroleum and chemical to equip explosion-proof law enforcement recorders, strengthen safety production supervision, the Ministry of Transport promotes the upgrading of intelligent law enforcement equipment for maritime, railway and other law enforcement units, the State Grid promotes intelligent inspection systems, integrates law enforcement recorders with AI analysis functions, and so on. There are also relevant national standards (GB) and industry standard machine international certifications to enforce the compliance of recorder products：

In addition, the 14th Five Year Plan and related supporting policies mention the hope of achieving breakthroughs in key technologies in the field of integrated circuits by 2025, enhancing the independent and controllable capabilities of the industrial chain, and reducing external dependence. The plan repeatedly emphasizes "autonomy and controllability". This does not mean closing the door to research and development, but rather having strong control over key links in the industrial and supply chains, ensuring safety and reliability, while having strong competitiveness. This means that under the premise of open cooperation, key technologies can be independently mastered through various means such as independent research and development, technology introduction, digestion, and innovation, avoiding being "choked" at critical moments. So, in terms of chip selection and related supply chain matching, Shiyao Electronics' law enforcement instrument product solution focuses on the national production ecology, even including domestically produced core (RSIC-V) chips.

At the product design level, Shiyao Electronics has always adhered to the industry standard GA/T 947-2015 for law enforcement recorders as the basis for product parameters and performance, and carried out in-depth business customization development based on actual usage scenario requirements, providing customers with distinctive law enforcement recorder product solutions, as follows:

1. The improvement of chip technology brings about the enhancement of battery life:Currently, the domestic chip process technology has been upgraded from 28nm to 22nm, and then to 12nm. The continuous improvement of the domestic chip supply chain has also brought better battery life to our products, providing us with more choices for product design.. For example, under the same performance parameters, its battery life can be improved by at least 10%; Or, with the same battery life, the performance parameters of its product can be improved by one level;

2. Super Standby:Its main feature is that when the device is in standby idle state, the overall current of the machine after the main CPU and camera system are completely turned off can be less than 10mA, achieving the goal of ultimate sleep power consumption;

3. Video stabilization function: There are mainly EIS stabilization based on gyroscope data and Sensor shift OIS optical stabilization.

3.1 EIS anti shake based on gyroscope data: By using algorithms to accurately match and synchronize the physical shake data recorded by the gyroscope with the exposure time of each frame of the image sensor, corresponding inverse transformations (translation, rotation, twisting) are performed on each frame of the image. The disadvantage is that a certain amount of frame angle is lost;

3.2 Sensor shift OIS optical image stabilization: By using a micro motor or electromagnetic drive to move the image sensor in the opposite direction, the optical path can still accurately project onto the sensor during the shaking process, physically canceling out the impact of shaking and completing the stabilization process before the image is captured by the sensor. The advantage is that there is no loss of image quality and the effect is natural. The disadvantage is that the cost is high and there is a certain volume requirement. Its effect is suitable for, for example, the video shown in:

4. Black light full-color night vision: With the deep integration of visual Soc and AI NPU, the "black light full-color technology" has been newly introduced, which can increase sensitivity by 2-4 times under the same sensor/lens, optimize low light brightness/color/ghosting performance. It has increased the product's sensitivity limit, optimized the product's color imaging level in low light environments, and provided users with an experience better than human visual perception. The comparison of its effects is as follows.

5. Real time transmission: Supports 4G/5G/Wi Fi and domestic single Beidou positioning, achieving a law enforcement mode of "on-site law enforcement+remote collaboration", solving the problem of insufficient grassroots police force, and achieving dual improvement of law enforcement compliance and efficiency.

6. Police linkage: The law enforcement recorder supports scanning codes, NFC touch, and platform push to trigger the acquisition of police information. Audio and video are automatically bound to police information, achieving zero error in case tracing and 100% accuracy in evidence correlation. This enables rapid response by police forces and precise synchronization with on-site situations, improving command and dispatch efficiency and law enforcement collaboration capabilities.

7. Pull out sensing solution:Equipped with a holster sensor, when a police officer pulls out their gun, the law enforcement recorder will automatically start recording and send real-time alerts, location, and on-site audio and video back to the command center. At the same time, it will be linked to surrounding law enforcement recorders and Skynet screens.. This system helps the command center to assess the situation, dispatch police forces, and record gun pulling incidents to evaluate their rationality, improve gun control and public safety response efficiency, and reduce public questioning.

8. Data Encryption:

8.1 A complete solution that supports AES data encryption and decryption;

8.2 Provide a comprehensive USB device management solution, as well as a docking solution that complies with the GAT 947.3-2015 industry standard for the data collection management platform, and is fully compatible with domestic operating systems such as UOS and Kylin Kirin.

Shiyao Electronics adheres to the corporate values of integrity, openness, transparency, agile innovation, and pragmatic progress. With sincere service, we win long-term cooperation from every customer and use reliable products to help the industry move towards a new chapter of digitization and intelligence.
