What is HDCVI ?

HDCVI (High Definition Composite Video Interface) is an over-coaxial-cable analog HD video transmission standard which developed in-house. The technology renders two HD video formats—1080P (1920×1080) & 720P (1280×720) by progressive scanning.

Technical Highlights

• HD Video format
  1920H(1920×1080) & 1280H(1280×720)
• Analog Modulation
  Uncompressed and crosstalk-free
• Transmission over coaxial cable
  Reliable and non-latency point-to-point transmission
• Auto Compensation & Long range transmission
  720P(1280×720): 500m via Φ75-3, 700m via Φ75-5
  1080P(1920×1080): 300m via Φ75-3, 450m via Φ75-5
• Composite video/audio/PTZ signals
  HDCVI composites video, audio and PTZ signals together and have them transmitted over coaxial cable.
• Two-way data transmission

What HDCVI Brings?

• Upgraded to analog HD seamlessly with Low-cost and simple installation value-added solution. Go after       the conventional analog system topology and give a full consideration to users’ operation habit.

• Megapixel & uncompressed image quality —1080P(1920×1080) & 720P(1280×720)
• Long range & non-latency reliable video transmission without additions of relay devices.
• Strong anti-interference capability & solid interface protection. Free of high-frequent electromagnetic           radiation; constant signal transmission
  and display without problems as frame drop and lock loss occurred.
• An open analog HD transmission system established and evolved industry chain developed to sustainably   improve the technical standard


Longer Transmission Distance

Both HDCVI and HD-SDI can transfer HD signal @720p/1080p, but HDCVI has a distinguished advantage at the transmission distance. With general transmission media, HD-SDI reaches 100 meters at most while HDCVI, at least, transmits 500 meters by using 75-3 cable and featuring low signal distortion rate.
Better Anti-Interference Capability
The anti-interference capability of HD-SDI solution is relatively poor when been placed against high-frequent radiation environment, which could lead to higher bit error ratio while the HDCVI adopts low-frequency modulation technology, making it free from the high-frequency wireless electric radiation to ensure stable video transmission at high image quality.



HDCVI adopts P2P transmission to ensure a smooth and reliable transmission; while the transmission of network camera is based on Ethernet and thus may lead to network jitter and packet loss.
The network HD features video buffer technology and the delay is controlled within 300 milliseconds in the general and fair networking environment; However, HDCVI features no latency capability for an outstanding real-time performance.
No Compression
For HDCVI, there is no compression processed to maintain its original effect and thus present in vivid image quality.


Lower Cost

Unlike HD-SDI, which posts high demands on cabling and installation; HDCVI solution inherits the same installing means of conventional
analog solutions, which is of great convenience and also decrease the cost.
Smart control
As HDCVI transmits multiple-signal (video/audio and dual-way data) over one cable, it realizes video/audio synchronized transmission and reverse-signal transmission control at the same time, such as PTZ and zoom control; which further simplifies the installation.
