Law enforcement recorders can record videos in real time, providing effective evidence for restoring the truth, and becoming the basic equipment for ensuring transparent law enforcement in all walks of life.

Hainuda has relied on more than 20 years of public safety industry experience and meets customer needs to launch a new generation of intelligent ultra-thin 4G law enforcement recorder DSJ-HYTV4A1 (hereinafter referred to as V4), integrating functional characteristics such as professional video recording, professional intercom, and public-specialty integration. On the basis of realizing the front-end audio and video recording needs, V4 further strengthens the support of front-end devices for back-end applications and helps the back-end efficient management work.

is thin and easy to use, improving the law enforcement efficiency of front-line personnel

20mm ultra-thin body, the ergonomic design closely adheres to the human body arc, and it is naturally and easily worn, and even front-line personnel will not feel burdened even if they wear it all day. Large-size PTT buttons, independent alarm buttons, emergencies, 1 second request for help, adding another layer of guarantee for security law enforcement.

V4 adopts a dual-battery design for main and backup batteries. The 3000mAh large-capacity main battery supports continuous recording for more than 8 hours, while the backup battery ensures that the battery is replaced and every key image data is not lost. Authoritative certification by the Ministry of Public Security, IP68 is dust-proof and water-proof, and bare metal is 2m-resistant to drops, thus achieving all-round protection of equipment data and hardware.

For law enforcement recorder products, video shooting is the most important and basic function. V4 supports 1080P high-definition video shooting and infrared night vision function, ensuring that people's facial features can be clearly distinguished in 5 meters under light conditions, and the personnel outline can be visible in 10 meters. 110° wide angle, combined with distortion correction algorithm, accurately collect more real details on the site. The pre-recording 30 seconds and delayed recording 30 seconds functions help restore the true story of the event. At the same time, the equipment supports recording and transmission of 4G videos, reporting on on-site dynamics in real time, and realizing visual command and scheduling of the law enforcement process.

V4 law enforcement recorder is equipped with a large PTT button, a professional intercom speaker and fine sound adjustment, which is comparable to a professional intercom, and can realize PoC voice intercom within the coverage of the public network. In addition, in conjunction with Hytera HyTalk Pro public-specialized integrated scheduling platform independently developed by Hytera, V4 can also realize interconnection with broadband terminals, narrowband terminals, and multi-mode terminals, instant communication, complete unified and efficient command of multiple departments, and meet the rapid scheduling needs of one call.

is comprehensive and efficient, helping the backend to improve management efficiency

V4 product supports outdoor Beidou, GPS, and AGPS combined positioning, and is combined with indoor Bluetooth positioning to achieve more accurate full-domain positioning. Even in places with poor signals such as parking lots, tunnels, underground shopping malls, etc., V4 can be used to track the location of front-line personnel in real time. It will help complete service assessments during normal work. In emergencies, peripheral support can be dispatched in a timely manner to help standardize duty and improve management efficiency.
