TVI is a abbreviation of “Transport Video Interface”.It is a new DSP-TVO technology.Many Chinese factories,such as Hikvision and Dahua,they use this technology to their new products line.HD-TVI solution solved the problem of HD-SDI.TVI can convert the digital signals to analog ones, it extends the transmission distance, reduces the total cost, and takes less storage capacity, HD-TVI is also based on coaxial cable, support HD video signal(1080P/720P), Audio signal, digital signal transmission.
The feature of HD-TVI:
1080P/720P( 25/30 fps) video signal
Long transmission distance at 300-500 m
No Video loss
Real-time preview without delay
Transmit video signal, audio signal and dual-way data communication, 3 signal transmission over one coaxial cable.
Follow same connection structure with original analogue system without cable (Coax / UTP) changed, which means users can just change their old analog cameras and DVRs to TVI cameras and DVRs to get a brand new1080p surveillance system, don’t need any other special knowledge and extra cost.

The advantage of HD-TVI compared with HD-SDI is
Longer transmission distance(without boost)
Better Anti-interference and Reliability
HD-TVI vs IPC
Compared with IPC, the advantage of HD-TVI is
No compression, so no video quality loss.
Real-time video display, without any transmission signal delay.
Low requirement for network bandwidth.
