OK, since no one seems to know the answer to that i'll ask what might be an easier question.
I have set up a spare NAS with the camera so I don't need to have a PC or NVR for now. This records everything fine. Live viewing through my browser is smooth. But playback with the web interface is jerky/stuttering. If I right click the video and download it to a local folder or if I use Windows Explorer to browse the NAS folders and play the video files directly with WMP or VLC, they play fine. So the video is recording fine, the NAS is able to stream the video smooth directly but through the camera's web interface is isn't smooth.
Does anyone know how to fix this?
Is there any software that works like the web interface and can read from the NAS?
I couldn't work out how to do it with iVMCS-4200. It wanted to read from it's only folders (PCNVR_RECORD_FIL\Package000) that it created.
Their 'Local Playback' software would only fine the physical drives on my PC, even when the NAS location was mapped as a drive.
Thanks again.
[edit]
I removed the Storage Server from iVMS and then Playback automatically showed the videos that are on the NAS. Unfortunately, iVMS is jerky/stuttering like the camera's web interface. I assume iVMS is getting the video via the camera as iVMS has no information about the NAS location.
