Audio
Encode
Type
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.
[Setting method]
Select a value from
the drop-down list
box.
Resolution
A higher resolution means better image quality.
NOTE
IP cameras support the different resolutions based on the
model.
[Setting method]
Select a value from
the drop-down list
box.
Frame
Rate(fps)
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.
[Setting method]
Select a value from
the drop-down list
I Frame
Interval(F
rame)
I frames do not require other frames to decode.
A smaller I frame interval means better video quality
but higher bandwidth.
[Setting method]
Select a value from
the drop-down list
Bit Rate
Type
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.
[Setting method]
Select a value from
the drop-down list
box.
Max bit
Rate(500-
16000)
Indicates the maximal value of the bit rate.
[Setting method]
Enter a value
manually.
