Camera highlights
1, low illumination solution, particularly suitable for the normal lighting situation meeting room.
2, To reach 1920×1080 pixel , the max video frame is 60/50 FPS . It definitely meet the requirement
for both high clarity and picture smooth .
3, video’s S/N ratio directly affect the HD video conference terminal’s image compression coding
efficiency. With 2D and motion-estimation based 3D noise reduction algorithm and U.S new
generation low noise sensor, VHD820 has effectively reduce noise;

8
4, The unique Iridix exposure dynamic control algorithm, based on the human eye model, makes the
image even exposure and strong sense of hierarchy; With the most advanced CMOS sensor which
support WDR ,camera can capture all images clearly in the strong contrast between black and light
environment(such as backlight);
5, 18×optical zoom
6. Completed Interfaces , support DVI(can convert to YPbPr and HDMI output ) interface , broadcast
level HD-SDI interface .
7, IR remote controller signal transparent transmission function : camera can receive signal from both
its own remote controller and terminal equipment controller, by transmitting the signal through VISCA
IN to terminal equipment IR receiver.

COM Control
In default working mode, the camera is able to be controlled via RS-232C command (VISCA IN) . the
parameter of the RS232C COM as following :
Baud Rate ：9600 Bit/S
Start bit：1bit ;
Data bit: 8bit ;
Stop bit : 1bit;
Code: None
Connected to power, the camera runs to the right middle position, with the farthest zoom rate, auto
focusing and default iris data. The camera run into the preset no.0 if it was saving. After finish this
initialization the users can control the pan/tilt/zoom via RS-232 command.
