Recording Parameters
Main Stream
The 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): 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.
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: The bit rate (in kbit/s or Mbit/s) is often referred to as speed, but actually defines the
number of bits/time unit and not distance/time unit.
Enable H.264+ Mode: The H.264+ mode helps to ensure the high video quality with a lowered
bitrate. It can effectively reduces the need of bandwith and HDD storage space.
A higher resolution, frame rate and bitrate setting will provide you the better video quality, but it
will also require more internet bandwidth and use more storage space on the hard disk drive.
Sub-Stream
The Sub-stream is a second codec that runs alongside the mainstream. It allows you to reduce the
outgoing internet bandwidth without sacrificing your direct recording quality.
The Sub-stream is often exclusively used by smartphone applications to view live video. Users with
limited internet speeds may benefit most from this setting.
Picture
The picture refers to the live picture capture in continuous or event recording type. (Storage >
Capture Schedule > Advanced)
Picture Quality: set the picture quality to low, medium or high. The higher picture quality results
in more storage space requirement.
Interval: the interval of capturing live picture.
Capture Delay Time: the duration of capturing pictures.
