Congure recording parameters.
Main Stream
Main stream refers to the primary stream that aects 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 resoluon 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
sacricing your direct recording quality. Sub-stream is
oen exclusively used by smartphone applicaons to view live video. Users with limited
internet speeds may benet most from this seng.
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.
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
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 and not distance/me unit.
Note
Higher resoluon, frame rate, and bitrate provide you beer video quality, but it also requires
more internet bandwidth and uses more storage space on the hard disk drive.
