Parameter Description
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 value depends on the selected resolution.
Bit rate control This parameter is available only when you set Bit rate
mode type to Constant bit rate. The options are as follows:
– Frame rate priority: Ensure the smoothness of the
– Image quality priority: Ensure the quality of the
Frame rate The frame rate is measured by the number of frames
displayed in a second.
A higher frame rate indicates clearer and smoother
images and higher bandwidth consumption.
Image quality This parameter is available only when you set Encoding
protocol to H.264 or H.265 and Bit rate type to
Variable bit rate.
Better image quality requires higher bandwidth.
Therefore, select proper image quality based on the site
requirements.
