6.5.2 Congure Recording Parameter
Steps
1. Go to
Conguraon → Record → Parameter to congure camera main stream and sub-stream
parameters.
2.
Congure recording parameters.
Main Stream
Main stream refers to the primary stream that aects data recorded to the hard disk drive
and will directly determine your video quality and image size. Comparing with the sub-
stream, the main stream provides a higher quality video with higher
resoluon and frame
rate.
Sub-Stream
Sub-stream is a second codec that runs alongside the mainstream. It allows you to reduce
the outgoing internet bandwidth without
sacricing your direct recording quality. Sub-stream
is oen exclusively used by smartphone applicaons to view live video. Users with limited
internet speeds may benet most from this seng.
Frame Rate
Frame rate refers to how many frames are captured each second. A higher frame rate is
advantageous when there is movement in the video stream, as it maintains image quality
throughout.
Resoluon
Image resoluon is a measure of how much detail a digital image can hold: the greater the
resoluon, the greater the level of detail. Resoluon can be specied as the number of pixel-
columns (width) by the number of pixel-rows (height), e.g.,1024×768.
Bitrate
The bit rate (in kbit/s or Mbit/s) is oen referred to as speed, but actually denes the
number of
bits/me unit and not distance/me unit.
Enable H.264+/Enable H.265+
The H.264+/H.265+ mode helps to ensure the high video quality with a lowered bitrate. It
can eecvely reduce the need of bandwidth and HDD storage space.
