Wision Technology focused on developing network cameras when it stepped into the security field in 2005. The company roots stem from a joint lab with the Mobile Video Network Technology Center, founded by the Peking University Shenzhen Graduate School. A&S International China Best Buys talks to Demi Piao, Overseas Sales Manager at Wision Technology, about the company's IP-based strengths.
Technology Focused
Wision Technology works under the supervision of its Chief Technology Officer Yong Zhao, the leader of Mobile Video Network Technology Center (MVNTC), who spent 15 years as a senior software technologist for Honeywell. The company teamed up with MVNTC to develop digital media processing, including compression and transmission of audio and video signals. It benefited from advanced video compression after the center cooperated with Texas Instruments to work on integrating AVS into the DaVinci HD system. The company was recognized by the government as a Chinese High-Tech Enterprise for its innovative intellectual property and continuous development of technology.
The company has invested in a R&D team with more than 50 staffers, most of whom have had at least five years of experience in surveillance. Along with edge devices such as IP cameras and HD cameras, the company developed software to program and manage surveillance systems. It also offers customized software for specific verticals.
The Network Video Post System was designed in-house specifically for video surveillance and management. It enables remote monitoring through a Web server or with mobile devices. “Operators can access the system by entering the device's proprietary ID number.” said Demi Piao, Overseas Sales Manager at Wision Technology.
Wision Technology also emphasizes interoperability. As a contributing member of ONVIF, it has participated actively in the development of open standards and developed ONVIF-compliant products. “Our products were tested for interoperability at the ONVIF Interoperability Demonstration & Reception,” Piao said. “We attended the meeting as one of 22 members from all over the world.”
HD IP-Based System
By employing high-tech know-how from the center and TI's DM355 digital media processor, the company launched its first 1.3-megapixel network camera in 2007. An upgraded camera adopting DM365 processor was released in 2009, featuring 1,080P video streaming at 15 fps. “Our products were widely deployed in Safe City projects for city surveillance in China, as well as for telecommunications and environmental applications,” Piao said. “They received high marks from the government, companies and end users.”
This year, the new HD network cameras emphasize real-time video at a resolution of up to 1,920 X 1,080 at 30 fps. The cameras adopt TI's DM368 processor and a 1/2-inch 5-megapixel progressive CMOS sensor. They use the H.264 high profile compression to stream HD video at low bit rate, saving at least 50 percent of bandwidth and storage. The combination of Aptina imaging technology and TI's processing chip enables high resolution imaging in multiple formats. “The camera is also a true plug-and-play surveillance device and eliminates the obstacle of learning IT knowledge for integrators and installers.” Piao said.
Based on its long-term investment and development in networking, Wision Technology continues to strengthen its technology innovation, along with enhancing interoperability and scalability
