Hikvision Introduces HD-TVI Technology with Its TurboHD Product Line

City of Industry, CA, December 15, 2014 Hikvision USA, the North American leader in cutting edge, multiple award-winning video surveillance solutions and products, is proud to announce the launch of TurboHD, a line of cameras and recorders that utilizes High Definition Transport Video Interface (HD-TVI) technology. This revolutionary technology allows users to send uncompressed, high-resolution video over coaxial cable. The TurboHD product family is comprised of full HD cameras and DVRs that offer seamless compatibility with multiple video formats, from standard definition analog to HD-TVI to megapixel IP. Other benefits of HD-TVI include absence of video delay in live viewing, bi-directional signaling, and highly efficient storage, adding up to an incredible breakthrough in the evolution of analog transmission.

TVT Launches TVI: New HD-over-Coaxial Solution

TVI and HD-SDI both are HD-over-coaxial solutions. However, bottlenecks for HD-SDI still remain, such as transmission distance, storage, and total cost. Now, TVT successfully developed the TVI solution, which is able to solve HD-SDI's previous problems by acquiring 90 percent of HD-SDI technology but conducting analogtransmission via coaxial cable. TVI can convert the digital signals to analog ones, it extends the transmission distance, reduces the total cost, and takes less storage capacity. Its distance can reach from 300 to 500 meters via coaxial cables.Furthermore,TVI transmits CVBS 75ohm analog signals, with resolution in 1080P and 720P at 30 frames per second, which is hard to be achieved by other HD-over-coaxial solutions. Users even can just change their old analog cameras and DVRs to TVI cameras and DVRs to get a brand new1080p surveillance system, which doesn't require any other special knowledge or extra labor cost.
