Main Stream
Main stream refers to the primary stream that aects 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
resoluon 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.
Resoluon
Image resoluon is a measure of how much detail a digital image can hold. The greater the
resoluon, the greater the level of detail. Resoluon can be specied 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
oen referred to as speed, but actually denes the number of
bits/me unit rather than distance/me unit. Two types including variable or constant are
available.
Enable H.265+
H.265+ is an
opmized 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 resoluon, frame rate and bit rate seng will oer you beer 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.
