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 with better video quality, but it will
also require more internet bandwidth and use more storage space on the hard 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.
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.

ANR

files in the local storage when the network is disconnected, and when the network is resumed, it
uploads the files to the device.

Storage > Schedule Settings > Advanced).
