As a key parameter for a high definition (HD) IP
camera, 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.
The following audio codec standards are supported:
 G.711_ULAW: mainly used in North America
and Japan.
 G.711_ALAW: mainly used in Europe and other
areas.
 RAW_PCM: codec of uncompressed audio data.
This codec is often used for platform data.
