Select Channel: In case of many channels, the users can select the channel to be set as required.

Code Stream Type: Composite Stream and Video Stream. The composite stream refers to the composite

coding of the audio and video. This selection allows transmission of both audio and video; if the video

stream is selected, only video but no audio is transmitted.

Resolution: Refer to the original size of the compressed image, which consists of CIF(352×288), 2CIF

（ 704×288 ） and 4CIF （ 704×576 ） . 2CIF is also called Half D1 and 4 CIF is also called Full D1. Some

products of our company support these three formats, but some only support CIF format. Please

distinguish in the technical parameters of relevant products. Meanwhile, if you modify the resolution,

you must save the configuration and then reset the video server. Otherwise, the modification will not

take effect.

of the current equipment will be dynamically displayed on the image screen.

Variable Code Rate and Constant Code Rate: The variable code rate refers to only considering the

image quality but not the size of code rate during the coding process at the cost of code rate; the

constant code rate refers to decrease the image quality properly at some times (such as image actions

are drastic) according to the code rate limit set by users at the cost of definition resolution. The quality

coefficient ranges from 4 to 31.

It's recommended that please select the constant code rate at 4 if the bandwidth is sufficient. If the

bandwidth is limited, please set the code rate according to the actual bandwidth.

Alarm Delay: It is set that when alarm occurring, the duration of the alarm output sound

Time Display: The format and reference of time display
