NOTE!

After enabling the sub stream, modify the parameters as required. The parameters for the sub stream have
the same meanings as that for the main stream.
1. Click Setup > Video > Video .
Modify the settings as required. The following table describes some major parameters.
Parameter Description
Video
Compression
Three options: H.265, H.264 and MJPEG (This function is not supported by some models).
Note:

Image Quality cannot be set when Video Compression is set to H.265 or H.264. When
set to MJPEG, only three frame rates are available: 1, 3 and 5; and Bit Rate, I Frame
Interval, Smoothing and U-Code cannot be set.

The bit rate changes to the default when you change the setting between H.264 and
H.265. The default bit rate for H.265 is half of that for H.264.
Frame Rate
Frame rate for encoding images. Unit: FPS (frame per second).
Note:
To ensure image quality, note that the frame rate should not be greater than the
reciprocal of shutter speed.
Bitrate Type

CBR: Constant Bit Rate, which means that the camera transmits data at a constant
data rate.

VBR: Variable Bit Rate, which means that the camera adjusts the bit rate dynamically
according to image quality.
Image Quality
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.
