Encoding settings interface as shown in Figure 4-16
Definition: Optional D1/HD1/CIF; Frame Rate: PAL is adjustable 1-25 frame, full frame rate of 25 is real-time
video; NTSC is adjustable 1-30 frame, full frame rate of 30 is real-time video.
Quality: optional level 1-8, among which level 1 is with the highest quality while level 8 is the lowest; quality
setting will directly affect the effect of video playback. Under the same resolution, the higher quality level is,
the clearer display effect it would have, of course, the video files will take up relatively large space. When some
channels do not need video which means no need of video or recording, the channel switch can be closed in
order to save the storage capacity of the SD card.
Recording: here the volume is the volume switch for device recording, when the channel is connected with a
pickup, it can open the recording of the channel.
Preview: Preview is open by default, the function of preview is to make video normally show in the channel,
if you turn off the preview, then the channel image cannot be seen, but in fact the image is still there and be
video recorded.
Sub-stream is important parameters when the video, audio and data are uploaded to the network via 3G, as
shown in Figure 4-17, and its settings is related to whether the video displayed on gServer platform is clear
and smooth. Of course, the most important factor for network transmission is the up and down rate of the local
network broadband. Video resolution can be set as CIF and QCIF.
1.The corresponding relationship between bit rate setting and the frame rate changing is shown as below,
the bit rate set here is the transmission rate of a channel.
2.The frame rate setting is changed according to the corresponding bit rate change; it can be set as bit rate
96 frame rate 10 in default. This setting is the current one that can guarantee fluency as well as a certain
resolution when 3G network transmits
audio and video, but you can set this based on your own network situation, if under good enough network
bandwidth , it can be set with higher frame rate and bit rate and it can also be set automatically.

1:f you select timer recording mode in "video mode" as shown in Figure 4-14, you need to set what
the timing period is.
Figure 4-18, move the cursor to the required time period; press the number keys on the remote
control to input. Timer recording mode is not commonly used, customers can use it according to the
actual situation, most of customers still choose the starting-up recording and alarm recording.
