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.

HDCVI
VS. HD-SDI
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 VS. IP
Reliability
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.
Real-time
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.
Highlights
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.
