VIVOTEK IP8130 사용자 설명서

 

 

The frame rate will decrease if you select a higher resolution�

■ Intra frame period

Determine how often to plant an I frame. The shorter the duration, the more likely you will get 

better video quality, but at the cost of higher network bandwidth consumption. Select the intra 

frame period from the following durations: 1/4 second, 1/2 second, 1 second, 2 seconds, 3 

seconds, and 4 seconds.

Video quality

•  Constant bit rate: 

Target bit rate: 

A complex scene generally produces a larger file size, meaning that higher bandwidth 

will be needed for data transmission� To regulate the bandwidth consumption and 

storage space for recording videos, you can select the Constant bit rate methodology. 

The firmware will try its best to contain the size of video packets within the limitation 

of a constant bit rate� This methodoloy enables easier calculation of the network 

bandwidth and storage space required for live viewing or video recording� 

   

The bandwidth utilization is configurable to match a selected level, resulting in 

mutable video quality performance� The bit rates are selectable at the following rates: 

20Kbps, 30Kbps, 40Kbps, 50Kbps, 64Kbps, 128Kbps, 256Kbps, 512Kbps, 768Kbps, 

1Mbps, 2Mbps, 3Mbps, 4Mbps, 6Mbps, and 8Mbps� You can also select 

Customize 

and manually enter a value�

•  Fixed quality: On the other hand, if 

Fixed quality is selected, all frames are 

transmitted with the same quality; bandwidth utilization is therefore unpredictable� 

When so configured, the frame-rate-per-second performance can be compromised 

in the event of insufficient bandwidth or network clogs� The video quality can be 

adjusted to the following settings: Medium, Standard, Good, Detailed, and Excellent. 

You can also select 

Customize and use the slide bar to designate image quality� 

Drag the slide bar to configure a quality level you prefer.
