To strengthen public security management, public security organs in many areas have introduced single-officer video and audio recorders for use in scenarios such as street patrols, traffic checks, and handling of public security incidents. The recorders support high-definition video and high-fidelity audio recording, capable of completely recording the entire law enforcement process.

With the development of smart technology, single-officer law enforcement audio and video recorders are gradually becoming intelligent. The new recorders support GPS positioning, real-time cloud uploading, and remote monitoring, enabling intelligent management of the law enforcement process.

With advancements in traffic management technology, traffic departments in many regions are promoting the use of smart alcohol detectors. These devices can quickly measure a driver's blood alcohol concentration at checkpoints or during mobile patrols, helping law enforcement officers effectively identify drunk driving.

Recently, a technology company launched a smart alcohol detector equipped with AI technology. This device combines a camera and sensors to monitor the driver's condition in real time. The AI ​​algorithm can determine if the driver is under the influence of alcohol and issue warnings when necessary.

With the promotion of a zero-tolerance policy for drunk driving, the market demand for portable alcohol testing devices continues to grow. Many manufacturers have launched lightweight, portable, and easy-to-use alcohol testing devices suitable for individuals, businesses, and traffic management departments.
