I have a Hikvision DS-7116HGHI-E1 DVR which works perfectly.
For live view in my office (which is 30 to 40 meters away) I watch on a PC using a web browser.
All cameras stream fine using sub-stream resolution.
But I like the functionality of the iVMS software and being able to have one camera larger in the middle with smaller panes around it.
The problem I have then is that (using the same computer) the software is terribly sluggish with lots of jittery video, like a bad 90s stop motion music video!
All cameras set to the same sub-stream resolution.
I can watch cameras fine on iVMS4500 on phone or iPad and the cameras run smoothly (using Fluent resolution, which is the same as sub-stream).
Anyone have suggestions on how to resolve this?
