Main Stream
Main stream refers to the primary stream that affects data recorded to the hard disk drive and will
directly determine your recording quality and image size.
Comparing with the sub-stream, the main stream can provide a higher quality video with higher
resolution and frame rate.
Frame Rate (FPS - Frames per Second)
It refers to the number of frames captured each second. A higher frame rate is advantageous
when there is movement in the video stream, as it maintains image quality throughout.
Resolution
Image resolution is a measure of how much detail a digital image can hold. The greater the
resolution, the greater the level of detail. Resolution can be specified as the number of pixel-
columns (width) by the number of pixel-rows (height), e.g., 1024 × 768.
Bitrate Type
The bit rate (in kbit/s or Mbit/s) is often referred to as speed, but actually defines the number of
bits/time unit rather than distance/time unit. Two types including variable or constant are
available.
Enable H.265+
H.265+ is an optimized encoding technology based on the standard H.265/HEVC compression.
With H.265+, the video quality is almost the same as that of H.265/HEVC but with less
transmission bandwidth and storage capacity required.
Note
A higher resolution, frame rate and bit rate setting will offer you better video quality, but it will
●
also require more internet bandwidth and use more storage space on the hard disk drive.
H.265+ encoding technology is only available for certain models.
