Video Configuration

You can set video parameters that your camera supports and view the current status of BNC output. If available,
you may also enable sub-stream and third stream as required.
NOTE:

This function may vary with models. Only some camera models support the third stream. To determine if your
camera supports this function, see the Web interface.

After enabling the sub or third stream, modify the parameters as required. The parameters for the sub and
third stream have the same meanings as that for the main stream.
1. Click Setup > Video & Audio > Video.
2. Modify the settings as required. The
following table describes some major
parameters.
A. Bitrate Type
a. CBR: Constant Bit Rate, which
means that the camera
transmits data at a constant
data rate.
b. VBR: Variable Bit Rate, which
means that the camera adjusts
the bit rate dynamically
according to image quality.
B. Frame Rate
a. Frame rate for encoding
images. Unit: FPS (frame per
second).
C. Image Quality
a. When Encoding Mode is VBR, you can move the slider to adjust quality level for images. Moving the
slider toward Bit Rate decreases the bit rate and may affect image quality. Moving the slider toward
Quality increases the bit rate and improves image quality.
D. Smoothing
a. Set the extent of smoothing. Choosing Clear means disabling Smoothing. Moving the slider toward
Smooth increases the level of smoothing but will affect image quality.
E. BNC Output
a. BNC output supports NTSC and PAL.
3. Click Save.
i. To ensure image quality, note that the frame rate should not be greater than the reciprocal
of shutter speed.
i. In a poor network environment, you can enable smoothing to get more fluent video.
