Description
The following audio codec standards are supported:
G711_ULAW: mainly used in North America
and Japan.
G711_ALAW: mainly used in Europe and other
areas.
RAW_PCM: codec of the original audio data.
This codec is often used for platform data.
A higher resolution means better image quality.
NOTE
IP cameras support the different resolutions based on the
model.
Frame rate is the number of images, shots, or frames
that a camera can take per second. The frames per
second determine the smoothness of a video. 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 frame 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:
Constant bit rate (CBR)
The compression speed is fast; however, improper
bit rate may cause vague motion images.
Variable bit rate (VBR)
The bit rate changes according to the image
complexity. The encoding efficiency is high and the
definition of motion images can be ensured.
Indicates the maximal value of the bit rate. the
different models may have different ranges, please
refer to actual product.
The video quality the camera output.
