Compression
The Compression section allows the user to define the compression settings of the video
streams 1, 2, and 3. The purpose of compression is to reduce the bandwidth and VMS storage
consumption.
Usually the stream 1 is configured to be the best quality stream for NVR recording purposes while
the stream 2 and 3 are configured to be with the basic quality for the live view of NVR or mobile
device, to minimize the computing power of NVR used for video decoding.

Description
Encoder Type
There are two encoder types available: H.264 (High Profile) and
MJPEG.
H.264 Profile
This item is available only if the Encoder Type is H.264.
The H.264 Profile defines the video compression scheme: High
Profile, Main Profile, and Baseline. These schemes vary from least
compressed, Baseline, to most compressed, High Profile. By
default, the H.264 Profile is High Profile, which provides the most
compression with the best video quality, but more computing power.
Some third-party video management system has longer latency or
takes more time to decode High Profile compression scheme, in this
case, you can select Main Profile or Baseline. In order to get the
