Dahua Technology Co., Ltd. is a provider of video surveillance products and services, with the world's 2nd largest market share, according to a 2015 IMS report.
Dahua Technology was founded in 2001. The company's products include security hardware and software from cameras, storages, controllers to monitors. In addition, it also renders solutions[clarification needed] in intelligent traffic system, intelligent building and etc.
In 2001, Dahua became the first company in China to launch an 8-channel real-time embedded digital video recorder. Since then, the company has continued to invest in building strong R&D capabilities for new technology and innovation. It has invested about 10% of its annual sales revenue in R&D since 2014. The company has four research institutes - Advanced Technology Institute, Big Data Institute, Chip Institute and Video Cloud Institute--and more than 6,000 R&D engineers and technical staff working in AI, IoT, Cloud services, video, cyber security, and software reliability and other technologies. Dahua has registered over 800 patents as of 2016.
According to the IHS 2014 report, Dahua enjoys the second largest global market share in video surveillance; meanwhile, it is the first Chinese corporate in security that established a global technology standard - HDCVI. Furthermore, Dahua ranked 3rd in the A&S International "Security Top 50" in 2017.
High Definition Composite Video Interface (HDCVI) is a standard in the CCTV and security camera industry, which is one of recent technologies for offering high definition solution to analog surveillance system (CCTV). HDCVI is a video transmission technology in high definition via coaxial cable, allowing reliable long-distance HD transmission at lower cost, while complex deployment is applicable.
As the HDCVI technology inventor and patent owner, Dahua has made it as a global open standard, providing open access for any third party, including competing manufacturers, to use HDCVI.
HDCVI modulates video signal to level and then transmit by adopting base-band and quadrature amplitude modulation; which is also the reason of its naming. This technology avoids the cross talk of CVBS and completely separates the brightness signal and hue signal, hence further enhances video quality. HDCVI offers two specifications -- 1920H (1920×1080) and 1280H (1280×720); which are compatible with the industrial standard 1080p(1920×1080) and 720p (1280x720).
In September 2016, the largest DDoS attack to date, on KrebsOnSecurity.com, was traced back to a botnet. According to Internet provider Level 3, the most commonly infected devices in this botnet were Dahua cameras and DVRs.
Dahua Technology as a leading solution provider in the global video surveillance industry has around 13,000 employees[non-primary source needed] all over the world. Dahua solutions, products, and services are used in over 180 countries and regions. It has 35 subsidiaries globally covering Asia, the Americas, Europe, Middle East, Oceania, Africa, etc.
