Parameter Description
Resolution 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.
Bit rate type The parameter is available only when you set Coding protocol
to H.264 .
The bit rate is the number of data bits transmitted in a unit of
time.
Bit rate value The parameter is available only when you set Bit rate type to
Constant bit rate .
Increasing the bit rate value improves the video quality but
consumes more bandwidth.
NOTE
l To ensure the video quality, you must set a proper bit rate value based
on the site requirements.
l To ensure video smoothness, the actual bandwidth is greater than the
bit rate value. When the bit rate is low, the required bandwidth is
generally 1.2 times of the bit rate.
Bit rate control mode The parameter is available only when you set Bit rate type to
Constant bit rate . The options are as follows:
l Frame rate priority : The frame rate stability is preferentially
ensured. However, if the scenario is complex or if the object
moves quickly in an image, the actual bit rate can be greater
than the preset value.
l Image quality priority : The image quality is preferentially
ensured. However, if the scenario is complex or if the object
moves quickly in an image, frame loss may occur or live
video may not be played smoothly.
Bit rate upper limit The parameter is available only when you set Bit rate type to
Variable bit rate .
The bit rate range is associated with the resolution.
Frame rate The frame rate is the number of frames displayed in a second.
Increasing the frame rate improves the video quality but
consumes more bandwidth.
Image quality The parameter is available only when you set Coding protocol
to H.264 and Bit rate type to Variable bit rate .
NOTE
Better image quality indicates that more network bandwidth is consumed.
Configure a proper image quality value based on the site requirements.
