How to distinguish the corresponding code streams in NVR and IPC?
(1) If not enable 'System>General Setting>App Live Self-adaption', when APP connects to
DVR/NVR, APP will not change device substream.
(2) If enable 'App Live Self-adaption', when APP connects to DVR/NVR, APP will change device
substream based on segmentation number in live preview interface. But if APP disconnects to
DVR/NVR, device substream will be changed back to its previous value.
Our N design like follows.Our App only use or change the second stream of camera.
All DVR and NVR both have three kind of streams: Main Stream, Sub Stream, Network stream:
The position as below:
Different Camera have different amount of code streams: such as some cameras have two
streams: Main stream/ Sub stream; some cameras have multiple streams: Three Streams , Forth
Streams...;
Case 1 Configuration.
Camera have two streams: Main stream/ Sub stream
NVR: Main stream --for record/ Sub stream--for playback/ Network stream--for Client web view
playback
Note:
A. will record the second stream of camera.It will use second steam in multi screen.
Because app only use the second stream of camera for display.
So if you have choosen the option “App Live Self-adaption”when APP connects to DVR/NVR, APP
will change device substream based on segmentation number in live preview interface. But if APP
disconnects to DVR/NVR, device substream will be changed back to its previous value.And this
will have the influence on NVR/DVR.
If do not choose option “App Live Self-adaption”,then will have no any influence on NVR/DVR.
Case 2 Configuration.
Camera have three streams: Main stream/ Sub stream/ Third stream
NVR: Main stream --for record/ Sub stream--for playback/ Network stream--for Client web view
playback
NVR/DVR will record the third stream of camera.It will use third steam in multi screen.
App only use the second stream of camera for display. Have no any influence on NVR/DVR.
Case 3 Configuration.
Camera have multi-streams: Main stream/ Sub stream/ Third stream/ Forth stream/ Fifth
stream.....
NVR: Main stream --for record/ Sub stream--for playback/ Network stream--for Client web view
playback
