Parameter Description Setting
Video Encode
Type The video codec determines the
image quality and network
bandwidth required by a video.
Currently, the following codec
standards are supported:

MJPEG
MJPEG is a standard intra-frame
compression codec. The
compressed image quality is
good. No mosaic is displayed on
motion images. MJPEG does not
support proportional compression
and requires large storage space.
Recording and network
transmission occupy large hard
disk space and bandwidth.
MJPEG is not applicable to
continuous recording for a long
period of time or network
transmission of videos. It can be
used to send alarm images.

H.264
H.264 consists of H.264 Base
Profile, H.264 Main Profile, and
H.264 High profile. The
performance of H.264 High
Profile is higher than that of
H.264 Main Profile, and the
performance of H.264 Main
Profile is higher than that of
H.264 Base Profile. If a hardware
decoding device is used, select
the appropriate codec based on
the decoding performance of the
device.
H.264 High Profile has the
highest requirements on the
hardware performance, and H.264
Base Profile has the lowest
requirements on the hardware
performance.

use H.264 Main Profile or
H.264 Base Profile.
