At the beginning of 2019, the General Office of the State Council publicly issued the "Guiding Opinions on the Comprehensive Implementation of the Administrative Law Enforcement Publicity System, Law Enforcement Whole Process Record System, Major Law Enforcement Decision Legal Review System", which put forward clear requirements for the full implementation of the law enforcement whole process record system and other related matters. The law enforcement recorder industry is developing rapidly with the help of the overall promotion of the rule of law. The Ministry of Public Security has taken the lead in deploying and using law enforcement recorders in political and legal organs across the country; in urban management, law enforcement recorders have been given an important mission. The application of law enforcement recorder related products and solutions has led to the birth of aviation, electric power, petrochemical field duty recorder, behavior recorder, service recorder and other products. The huge market potential and broad development space provide a new opportunity for Shenzhen Yiyun Technology Co., Ltd. (hereinafter referred to as Yiyun Technology) to launch EV880 audio and video law enforcement instrument. EV880 audio and video law enforcement instrument is a law enforcement recording terminal that can provide users with cluster voice, multimedia, visual command and dispatch services through different wireless channels such as 3G/4G and WIFI networks. EV880 is remarkable in all aspects of overall industrial design, functional configuration, product performance, etc. Combined with the integrated communication platform, it allows users to calmly realize one-button photo/picture return, voice/video intercom, command and dispatch, business management, etc. Functions provide solid and effective business support for industry users in scenarios such as multi-department linkage command, major group event handling, natural disaster rescue, and large-scale security. Today, let's appreciate and evaluate the new EV880 launched by Yiyun Technology, and feel the black technology contained in it as a whole. A professional design, convenient operation, 225-degree rotatable camera lens Yiyun Technology has long been committed to the research and practice of industrial design, and has repeatedly won international awards in the field of design. EV880 from the perspective of product design, it is small and exquisite, rich in layers, and the overall structural design makes it look professional, concise and agile. Function keys are distributed on both sides in an orderly manner according to industry experience and user habits, and the key distribution is more reasonable. Commonly used PTT intercom keys and important emergency alarm keys are distinguished by exclusive colors. PTT intercom keys are very conspicuous. On the left are quick alarm keys, intercom keys, recording keys, photographing keys and video keys in turn. The colors are eye-catching and the levels are clear. In case of emergency, the operation instructions are clear and misoperation can be avoided as much as possible. On the back is a 3.5-inch touch display. The camera design that can rotate 225 degrees at the top allows users to obtain a larger shooting angle. When shooting, the lens and the screen can be on the same side, allowing the subject to see the shooting picture, fully embodying the modern concept of sunshine law enforcement. In addition to facilitating users to obtain a better adjustable shooting angle according to specific scenes, it is also more cool and more technological. In addition to its application in public security departments, the EV880 law enforcement instrument also provides services in commercial fields such as hotels, logistics, warehousing and transportation. It is based on this consideration that Yiyun Technology has also added design elements of civil products to its design. For example, a large number of soft muscle lines are used on curved surfaces and sides to enhance the holding experience, while incorporating more color combinations, making the products look like they not only have the professional sense of the industry market, but also full of technological flexibility. Second, the high-efficiency video coding technology EV880 is equipped with Qualcomm 450 Xiaolong 8-core processor and Android 7.1 operating system, and comes standard with 3600mAh removable battery. H.265's efficient video coding technology can achieve low bandwidth and high compression, making the on-site shot images brighter and better, and storing and transmitting more high-definition videos with smaller storage capacity. EV880 can access the network channels of the three major operators, and supports Bluetooth, wifi, NFC and other Internet of Things link methods at the same time. In the case of poor network, users can have one more choice, thus ensuring the execution of key tasks. It is worth mentioning that the adoption of NFC is rare in similar products, which undoubtedly allows law enforcement instruments to be used in more scenarios, such as check-in, access control, data reading and other functions. EV880 has built-in Beidou II and GPS combined positioning module, GPS cold start positioning, records the incident at any time, and ensures the integrity and availability of evidence. EV880 provides cluster intercom, one call and one call. Through intercom APP, personnel are grouped, and personnel in the group can carry out cluster intercom. Command and dispatch work becomes so simple! From the dimensions of response speed, network status, map positioning, standby time, etc., we measured the three scenes in the underground garage, the 18th floor indoor and outdoor respectively. Its performance is comparable to the high-end brand mobile phones on the market at present. In the video state, the working time is as high as 8.7 hours. Three clear voice, high-definition video EV880 is equipped with high-power speakers, and adopts dual-wheat noise reduction and human voice recognition technology, with loud and clear sound quality. 16 million pixel camera, 6 infrared lights, F2.2 aperture, 106-degree visual angle, both day and night, can easily obtain high-definition image quality, ensure accurate entry of on-site conditions, clear and bright images, and fast preview without stagnation. At night, the facial features of the characters can be seen clearly at an effective shooting distance of 5m. The shooting ability in low illumination environment at night can clearly see the face 5 meters away. 106 wide-angle shooting, 1080P "touching" image quality under 16 million pixels, and one-click capture in the video state, making the evidence form multidimensional. Four sturdy and durable, waterproof, dustproof and anti-drop EV880 conforms to the "three defenses" standard: it has a 1.2m anti-drop design, can easily cope with all kinds of harsh environments, falls from a height of 1.2 meters to the ground, has no obvious wear on the surface, and has normal function. Soak in water for a long time and still work normally. In addition to the terminal, Yiyun Technology also provides a mobile audio and video converged communication platform with perfect functions and structured management. EV880 law enforcement recorder is a unified communication platform controlled by the command center in practical application. The platform can obtain its positioning, patrol track, operation log, attendance and other information at any time. It can also realize remote voice intercom, real-time image transmission or video recording, personnel frame selection and scheduling, information distribution and other functions with front-line terminals, so as to assist the leadership in making rapid decisions and issuing instructions, so as to truly strategize and win thousands. The EV880 law enforcement recorder launched by Yiyun Technology is full of bright spots. First of all, the size of the body is small and portable when matched with the screen, and the buttons on both sides are also very reasonable and comfortable. The rotatable camera, which is rare in the industry, has a sense of science and technology and is impressive. As the most important video recording function of the law enforcement recorder, the imaging effect brought by the 16 million pixel camera is up to expectations, and high-quality pictures can be easily obtained during the day and night. Overall, this law enforcement recorder is worth recommending!
