Parameter Description
Encoding Set the coding protocol based on the site requirements.
protocol The options are as follows:
– H.264: The H.264 protocol requires relatively small
– MJPEG: The MJPEG protocol decodes and displays
– H.265: The H.265 protocol is bandwidth-conserving
Encoding The options of H.264 profiles include Base profile, Main
complexity profile, and High profile. Among these profiles, the
baseline profile has the lowest encoding compression
performance and lowest requirements on hardware
decoding performance, while the high profile has the
highest.
Resolution A higher resolution indicates clearer images and higher
bandwidth consumption.
Bit rate type This parameter is available only when you set Encoding
protocol to H.264 or H.265.
The bit rate is measured by data bits transmitted in a
unit of time.
– Variable bit rate: The bit rate varies depending on
– Constant bit rate: The constant bit rate remains the
Max. bit rate This parameter is available only when you set Bit rate
type to Variable bit rate.
The bit rate range depends on the selected resolution.
Bit rate value Average bit rate when Bit rate type is set to Constant
bit rate.
The bit rate range depends on the selected resolution.

set to 110%. If the bit rate is incorrectly configured
for images with great dynamic changes, the images
will be unclear.
