I have a Hikvision NVR (DS-7616NI-I2 / 16P) with 4 cams currently, 2 of them display their main streams at their max resolutions fine (one is a Hik and the other a non-name cheapy) but the two Dahua's only show their sub streams as options at lower res's.
If I view them directly via their web interfaces, the pictures are perfect high res but in the NVR only the low res sub stream is an option (at a crappy bit rate).
If I use a custom protocol rather than ONVIF, I can get the high res feed but in the case of one of them that's a PTZ, I lose the PTZ capability!
Any suggestions? I've tried searching for solutions but I don't even know what to search for! The Dahua models are DH-SD22204T-GN and IPC-HDBW4431R-ZS if that matters.
Thanks,
Rob
