Description
A higher resolution means better image quality.
IP cameras support the following resolutions based
on the model:
 1920 x 1080 and 640 x 360
 1280 x 960 and 640 x 480

1280 x 720 and 640 x 360

D1/Common Intermediate Format (CIF)/Quarter
CIF (QCIF)
NOTE
Recommending bit rate is 704x576:2000kbit/s;
1280x720:4000kbit/s; 1920x1080:8000kbit/s. If in lower
bit rate, cameras will automatic reduce frame rate.
The frame rate is used to measure displayed frames.
A higher frame rate means smoother videos. A video
whose frame rate is higher than 22.5 f/s is
considered as smooth by human eyes.
Frame rates for different frequencies are as follows:
 50 Hz: 1–25 f/s
 60 Hz: 1–30 f/s
NOTE
The frequency is set on the Device Configuration >
Camera page. The biggest mjpeg coding format frame rate
is 12 frames per second.
I frames do not require other frames to decode.
A smaller I frame interval means better video quality
but higher bandwidth.
The bit rate is the number of bits transmitted per unit
of time.
The following bit rate types are supported:
 CBR
The compression speed is fast; however, improper
bit rate may cause vague motion images.

VBR)
The bit rate changes according to the image
complexity. The encoding efficiency is high and the
definition of motion images can be ensured.
