LMcClure Thanks for your reply. I too noticed there is provision for a viewing grid that can display 16 cameras simultaneously so that shouldn’t pose as a problem, although 3 rows of 4 may have allowed me a bigger images from each camera.
In regard to the hard drives in the NVR units, I’m seeking thoughts on whether to to record all 12 cameras, from the 2 NVR units, on one Hard Drive in the host PC or on individual Hard Drives in each on the NVRs, From what you’re saying it looks unlikely that I’ll be able to access either NVR from the host PC.
I guess I don’t need to record on the NVRs it depends on whether all the options such as: motion detection, alerts etc, provided in the NVR software are available in the Zviewer software. Perhaps there is another package that will do more than Zviewer; Blue Iris or Genius Vision??
Either way I still have to use the Zmodo NVRs to power the cameras.
