The timely detection and disposal of dangerous items such as knives and firearms in law enforcement, security patrols, campus security, public transportation, and other scenarios are directly related to public safety and social stability. The traditional method relies on manual visual recognition, which is not only inefficient and has a high rate of missed detections, but also difficult to achieve real-time warning and rapid response.
1、 Why do audio and video law enforcement recorders require tool/firearm identification?

5G law enforcement recorders are widely used in law enforcement recording, security patrols, campus security, public transportation inspections and other scenarios, and are the first recorders of on-site situations. However, when faced with sudden violent incidents or suspicious individuals carrying dangerous goods, traditional recorders can only "record" and cannot "identify" them——
Passive recording, unable to warn: danger can only be discovered after replay, missing the best disposal opportunity;
• Relying on the naked eye, with a high rate of missed detections: In densely populated areas, it is difficult to quickly locate dangerous goods solely with the human eye;
• Delayed response and passive security: The process from discovery to reporting and disposal is lengthy and inefficient.
The intelligent recognition function of knives/firearms upgrades 4G/5G law enforcement recorders from "recording" to "thinking" - real-time analysis, active warning, and millisecond response.

Deep learning+object detection, precise identification of various dangerous goods
The tool/firearm recognition algorithm is based on deep convolutional neural networks (CNN) and object detection models. Through training and iterative optimization of massive image data of dangerous items such as knives and firearms, it achieves efficient detection of prohibited items such as controlled tools (samurai knives, swords, etc.), blunt objects (wrenches, iron bars, etc.), and firearms (sniper rifles, firearms, etc.) in the form of long strips and firearms. The algorithm integrates multiple strategies such as color segmentation and unique size feature filtering, effectively reducing false alarm rates.
Highlight 2: End cloud collaboration, millisecond level real-time recognition and alarm
Relying on the powerful end-to-end AI computing power of the audio and video recorder (eight core high-performance CPU, deeply customized Android system), dangerous goods recognition is completed in real-time on the device side, without relying on network transmission, ensuring millisecond level response. The recognition results are synchronously uploaded to the MCS8 multimedia communication system platform. Once dangerous items such as knives and firearms are detected, the system immediately triggers an alarm and captures pictures, pushing the warning information to the command center and relevant personnel in real time, achieving a closed-loop system of "recognition alarm disposal".
Full scene adaptation, stable operation day and night
The audio and video recorder is equipped with 4 infrared lights, with a facial recognition range of up to 3 meters and a human detection range of up to 10 meters; Supports 4K/2K high-definition recording and H.265 video compression technology. Combining the adaptive ability of AI vision algorithms, it can stably output recognition results in complex environments such as strong daylight, weak nighttime, rainy days, and backlighting, truly achieving all-weather protection.
Autonomous and controllable, safe and reliable
The audio and video 5G law enforcement recorder is equipped with a single Beidou high-precision positioning chip. From hardware to software, from algorithms to platforms, the entire chain is autonomously controllable, meeting the strict requirements of industries such as public security, procuratorial, judicial, and judicial departments for information security and autonomous controllability.
3、 These scenes can all be used!
The tool/firearm recognition function can be widely applied in multiple industry scenarios:
Law Enforcement Duty: During on-site law enforcement by public security, traffic police, and armed police, real-time identification of dangerous items such as knives and firearms carried by suspicious individuals is carried to assist law enforcement personnel in quickly assessing and disposing of them;
Campus security: patrol at the school entrance and around the campus, promptly detect suspicious individuals carrying dangerous goods, and build a strong campus security defense line;
Public transportation: transportation hubs such as subways, train stations, and airports assist security and patrol personnel in quickly identifying dangerous goods and improving public safety levels;
Key venue security: Government agencies, large-scale events, shopping malls and other crowded places should implement intelligent inspection of dangerous goods to fill the blind spots of manual inspection;
• Factory and industrial park: Conduct safety patrols in industrial parks, mining areas, and other places to promptly detect personnel carrying dangerous goods in violation of regulations.
