Description
Select one of the following options: Main Stream, Sub Stream
Select one of the following options:
H.264B: Baseline Profile. Uses up to 50% less bandwidth than MPEG4 and up to 80% less than
MJPEG.
H.264: Main Profile. Uses less bandwidth than Baseline Profile at the same quality.
H.264H: High Profile. Uses less bandwidth than Main Profile at the same quality.
MJPEG: Uses the most bandwidth but produces excellent image quality with access to every
image in the stream.
H.265：Uses less bandwidth than H.264H at the same quality.
Turn ON smart codec to save bandwidth in codec optimization.
Select a resolution. Recommended bit rates for each resolution appear as the Reference Bit
Rate.
For NTSC cameras, select a frame rate between 1 and 60 frames per second. For PAL cameras,
select a frame rate between 1 and 50 frames per second.
Select one of the following options:
CBR (Constant bit rate): Recommended for low bandwidth environments. Required if MJPEG
compression is used.
VBR (Variable bit rate): Bit rate changes according to the complexity of the scene. Select a
Quality level between 1 (lowest) and 6 (highest).
Select a bit rate from the list of options, using the Reference Bit Rate as a guide. In VBR mode,
bit rate refers to the maximum bit rate.
If H.264 compression is selected, you can specify the number of P-frames between I-frames.
The recommended I-frame interval is two times the frame rate.
Select a SVC step (1~3).
Select the check box to add a digital watermark to the recorded video. The Watermark Text can
only contain letters, numbers, underscores (_), and hyphens (-), without any spaces.
