Description
You can set the dynamic bit rate only when you set Coding
protocol to H.264.
After you set the dynamic bit rate, the camera will automatically
use the dynamic bit rate to deliver more clear live video or
recordings when an alarm is generated. After that alarm is
cleared, the camera restores the bit rate you set for the data
stream.
NOTE
l It is recommended that you set the dynamic bit rate to a value greater
than the bit rate you set for the data stream.
l The dynamic bit rate is valid only for primary streams.
The full frame rate is a frame rate that the IPC collects using a
sensor or chip.
NOTE
The full frame rate must be greater than or equal to the frame rate you set
for the data stream.
Set the coding protocol based on the site requirements. The
options are as follows:
l H.264: The H.264 protocol requires relatively small
bandwidth to ensure the video quality.
l MJPEG: The MJPEG protocol decodes and displays each
frame independently without referring to the previous and
next frames. This protocol has a small compression ratio and
requires large bandwidth to ensure the video quality. This
protocol is suitable for video editing.
NOTE
l Before connecting cameras to a surveillance platform, ensure that the
surveillance platform supports coding protocols on cameras to
properly play live video and record video. If the surveillance platform
does not support coding protocols on cameras, change the coding
protocols on the cameras to that supported by the surveillance
platform.
l Local recordings support the H.264 protocol only.
The parameter is available only when you set Coding protocol
to H.264.
Two options are available: H.264 Base Profile and H.264 Main
Profile. Compared with H.264 Base Profile, H.264 Main Profile
demonstrates a better performance in encoding and compression,
and has higher requirements for the decoding performance of the
hardware device.
Increasing the resolution improves the video quality but
consumes more bandwidth.
NOTE
l The PAL standard primarily applies to China and Europe.
l The NTSC standard primarily applies to America and Japan.
