Technical Field

[0001] The present invention relates to the technical field of law enforcement recorders, and in particular to a head-mounted recorder and a use method thereof. Background Art

[0002] Law enforcement recorders are widely used in on-site law enforcement tasks of law enforcement units and have gradually become one of the important work equipment of government law enforcement departments.

[0003] The patent with application number 202310617869 discloses a head-mounted law enforcement recorder. This patented technology can adjust the direction of the information collection part of the law enforcement recorder, so that the law enforcement officer can feel the position of the law enforcement recorder. However, when this patented technology is actually used, it has the following disadvantages: since the staff are facing people or things to enforce the law, the usual head-mounted law enforcement recorders only have front-view cameras, but the actual law enforcement environment in which the law enforcement officers are located is complex. When unexpected situations occur during law enforcement, things related to law enforcement may also happen behind the law enforcement officers in a short time. If the law enforcement officers do not have time to react and use the recorder to collect information, it is bound to cause poor law enforcement. Moreover, although the patent has designed a variety of adjustment angles for the front-view camera, when the rear-view camera is actually used, the angle cannot be adjusted synchronously with the front-view camera, which affects law enforcement shooting. Summary of the invention

At the same time, it can also ensure close communication between the law enforcers and their colleagues. The help button 28 is set on the communication terminal 2. When the law enforcer touches it, the signal can be remotely transmitted through the wireless communication module 27 to achieve online communication, and the signal can also be transmitted to colleagues at a close distance.

[0037] Embodiment 2:

[0038] Refer to Figure 1-Figure 8 As shown, an embodiment of the present invention provides a method for using a head-mounted recorder, comprising the following steps:

[0039] Before the law enforcer enforces the law, when it is necessary to adjust the shooting angle of the recording device, the front and rear viewing angles are adjusted synchronously. Position adjustment: pull out the fixed shaft 9, and the return pin 24 is facing the adjustment part 22. At this time, the front view camera 10 is rotated, and the front view camera 10 drives the traction rope 12 to drive the slider 16 to slide in the limit sleeve 25 through the rocker arm 8. At this time, the slider 16 can push the rotating column 15 to move in the arc groove of the adjusting column 14 to rotate the adjusting column 14. The rotation of the adjusting column 14 drives the first flexible shaft 5 to rotate through the second flexible shaft 11. The first flexible shaft 5 makes the rear view camera 4 cooperate with the front view camera 10 to rotate to a suitable position for shooting through the installation shaft 3. After adjustment, press the fixed shaft 9 to make the limit magnet 13 and the fixed magnet 17 magnetically adsorbed. After the position adjustment is achieved, the positions of the front view camera 10 and the rear view camera 4 are fixed. Here, when the front view camera 10 adjusts the angle downward, the rear view camera 4 can adjust the angle downward synchronously. The same is true for upward, so that the law enforcer can achieve synchronous shooting;

[0040] Actual shooting: The front-view camera 10 can shoot law enforcement video in front of the law enforcement officer. At the same time, the rear-view camera 4 shoots in real time and can record the blind spot behind the law enforcement officer, so that the law enforcement officer can record the video of the blind spot behind him at any time in a complex environment. The video footage shot by the front-view camera 10 and the rear-view camera 4 is transmitted to the control and command center through the processor 29 and the wireless communication module 27. The Bluetooth module 30 and the processor 29 cooperate with each other to realize short-range communication between colleagues. The rescue button 28 cooperates with the wireless communication module 27, the front-view camera 10 and the rear-view camera 4 to achieve remote communication. At the same time, you can also call for help at any time with one click to achieve efficient law enforcement.
