It dawned on me that there doesnt appear to be any instructive documentation for the interface in the attached screen grab. If it exists please feel free to post a link, but what stands out the most about the documentation I have found is that its written for older HDCVI technologies. The NVR is a NV4108E-HS.
For my system, the PTZ controls to the right are wasted space, but the controls to the left could have benefited by at least some mouse-over popup information. If Im looking at this screen from a computer in a different city, how would you set it up to view one or more cameras, change resolution/streams, etc?
