What is HD-TVI

Even we enter into the digital era, analog surveillance technology doesn’t stop its innovation. Besides the HD-SDI and HD-CVI (in-house technology of Dahua), today the Hikvision and other camera manufacturers announce HD-TVI cameras release.  HD-TVI means High-Definition Transport Video Interface,  HD-TVI is based on traditional coaxial cable for video and data transmission, it supports not only 720P/1080P video signal but also includes audio, data signal over long distances up to 500 meters

Background study

At present, there are approximately 100 million coaxial cables are deployed for analog camera connections. In the next 3-5 years, they will be replaced with a high-definition camera. However, some users start to worry they have to rewire, re-install or add new network devices for upgrading. This group of users prefers the economical and easy solution to upgrade an existing system to HD, rather than adopting the IP camera. In this context, the HD-SDI and HD-TVI technologies were born.

HD-TVI advantages

Among current HD solutions, the distance of transmission, compatibility, and cost are always problems for both manufacturers and users. In this context, HD-TVI technology as a brand-new analog HD solution emerges in the market. Overall, the HD-TVI technology can provide a more economical, easier to install, and use solution for high-definition analog surveillance systems.

The HD-TVI can convert digital signals to an analog signal for expanding its transmission distance, lower total cost, reducing total video storage space. Through coaxial cable, the video transmission distance can reach up to  300~500 meters without obvious video quality loss.  In addition, the HD-TVI can transmit CVBS 75Ohm analog video signal with a resolution of 720P and 1080P at 30fps, which are difficult tasks to adopt other HD coaxial solutions. Merely replacing the existing analog camera and DVR with the latest HD-TVI camera and DVR, users can upgrade their surveillance system to a brand new 1080P HD system, this doesn’t require extra installation knowledge and cost.

• Analog HD high video quality 720P/1080P resolution
• Transmit video and audio signal, and data signal over coaxial cable
• No quality loss and delay for HD video transmission
• Impressive long-distance transmission capability
• Easy to upgrade your existing analog system to an HD system
