Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of law enforcement instruments, and in particular to a law enforcement instrument with AI noise reduction. Background Art
[0002] Body cameras, also known as body cameras or law enforcement cameras, are portable devices used to record on-site footage of law enforcement officers performing their duties. Typically equipped with a camera and microphone, they record video and audio in real time, providing objective and authentic evidence for law enforcement activities. The use of body cameras helps improve law enforcement transparency, protect the legitimate rights and interests of law enforcement officers and the public, and regulate law enforcement practices and prevent abuse of power.
[0003] At present, body cameras usually have AI noise reduction functions, and the AI voice noise reduction function on body camera means that the recording files can record the conversation content of law enforcement officers more clearly and accurately. When using existing body cameras with AI noise reduction, law enforcement officers fix them through a back clip fixing base, then fix the back clip to the shoulder position of the uniform, and then fix the lower part of the body of the body camera through a magnetic fixing card structure to wear the body of the body camera. However, when using existing body cameras with AI noise reduction, due to the differences in the body shapes of law enforcement officers, the fixed-length back clip may not be able to adapt to the shoulder width and comfort requirements of everyone. Therefore, the length of the back clip of the body camera needs to be adjusted. However, when adjusting the length of the back clip on the body camera, multiple holes are usually set on the back clip, and the length is adjusted by passing the fixing strap through different holes. The fixed holes may not perfectly fit everyone's body shape, resulting in discomfort or pressure when wearing.
[0004] Therefore, it is necessary to provide a new law enforcement camera with AI noise reduction to solve the above technical problems. Utility Model Content
