5.4.3 Congure Recording Parameter

Steps

1. Go to Conguraon → Record → Parameter .

2. 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.
