Figure 4-25 Effect Set - Mode
The camera supports 6 video effect modes. Users can set and save Name, ICR
control; Brightness, Sharpness, Hue, Contrast, Saturation, and 3D denoise
parameters for each mode. Click "Factoryset" to restore it to default settings.
In the Mode call, users can set effect mode call status and call period.

4.5.1 Video Settings
Users can set the video parameters in the format of H.264 major or minor
stream and MJPEG , such as resolution, frame rate, code rate, and IP rate.
stream
Resolution:
For H.264 major stream, the resolution of VH110-A2 series comes up to
1920×1080, with 1280×960 and 1280×720 optional;
For H.264 minor stream, the resolution comes to 640×480, 320×240 and closed.
For MJPEG stream, the resolution of VH110-A2 series comes to 1920×1080,
with 1280×960 and 1280×720 optional and closed
Frame Rate: the number of compressed frames produced by camera per
second.
The bigger the frame is, the better the image continuity will be, but the CPU

The camera has rich white balance modes, including Auto, Manual,
Incandescent light, Cool white fluorescent light, Sun light, Cloudy and Natrium
light. If set to manual mode, you can set the red gain and blue gain.

performance is lowered.
The smaller the frame is, the worse the image continuity will be, but the CPU
could handle more events.
The maximum frame rate for H.264 is 30fps. The maximum frame rate for
MJPEG is 5fps.
GOV number: GOV number means the ratio of I frame to P frame in compressed
video images.
The bigger the value is, the less the data quantity is and the less network
resource it occupies.
Max. GOV number can be set to 60.
Bit Rate: There are 2 modes of bit rate: variable rate (vbr) and constant rate
(cbr).
The variable rate can adjust the bandwidth that it occupies automatically
according to the complexity of image, because the complexity of real video
sequence keeps changing, details, speed, etc, and the variable rate setting mode
can be used to choose how much bandwidth should be used. If the video gets
more details and moving fast, then it takes up more bandwidth to transmit, and
reversely it occupies less bandwidth. When the setting goes with constant bit
rate, then the image is transmitted under a constant bandwidth.
Bit Rate: You have to set the upper limit of bit rate if "vbr" is selected; the
stream size will be fixed if "cbr" is selected and the stream size is defined in the
"Bit Rate". For major stream, the bit rate upper limit can be
~10000kbps
256kbps ; for minor stream, the bit rate upper limit can be
256Kbps~ 2000 Kbps.
Image Quality: it can be set under MJPEG stream. Options: Highest, High, Average,
Low and Lowest. The higher the image quality is, the more bandwidth it will occupy.
