Yes because of the high bandwidth. It wll no let me change the substream, only the main, which i do not want to do since the main stream is the recording stream. What ports are you using?
Not sure what you mean by IP PTZ interface. I normally adjust the streams under the audio/video tab thru web browser or by changing the setting in the IVMS software.
That deff needs a software update. So switch to port 80 and i should be able to adjust both steams just no motion recording?
Seems be a software/firmware issue when using Hik NVR's or mobile IVMS app.
There is currently no fix as far as I know. Hopefully it's just a firmware update. There is no substream if using a Hik NVR or IVMMS. You can change the quality of the substream and nothing will happen. It will only allow you to change the main stream but that is the recording stream and you would not want to do that. I just switch the camera out with my V1 3x. The original works fine with both streams and I like the wider viewing area!
Yes the mobile iPhone Ap. it's the square box icon to choose video quality. Gives the options of clear...fluent...custom. Under custom you can can choose either stream that you would like make the the adjust to.
The mobile app is IVMS-4500 I'm using.
