Description
Setting
Dynamic
bit rate
When a camera triggers an alarm
(temperature alarms excluded), the camera
automatically uses the dynamic bit rate to
ensure clear video effect. When alarms are
cleared, the camera restores the bit rate set in
the stream.
[Value range]
1080P: an integer ranging
from 1024 to 8192
720P: an integer ranging
from 512 to 8192
D1: an integer ranging
from 300 to 4096
[Default value]
4096
[Unit]
kbit/s
NOTE
The dynamic frame rate and
dynamic bit rate must be
enabled simultaneously.
You are advised to set a
dynamic bit rate that is greater
than the bit rate set in the
stream.
Dynamic bit rate is valid only
for primary streams.
Collected
frame rate
These frame rates are collected using a
sensor or chip.
[Default value]
25Hz
NOTE
The collected frame rate is not
less than the frame rate set in the
stream.
Layered
encoding
Enabling the layer encoding will decrease
video size but increase the requirements on
the encoder.

Coding
protocol
You can set the video encoding protocol as
required. The options are as follows:
H.264
: Ensuring the video quality, this
encoding protocol supports the minimum
bandwidth occupation.
MJPEG
: Each frame can be decoded and
displayed independently without referring
to the previous and next frames. The
compression ratio is small, and therefore
large bandwidth is required to ensure the
video quality. This encoding protocol is
suitable for video editing.
[Default value]
H.264
