Was helping someone with a 12 camera 3MP each, installation with one NVR. The PC is Windows 8 Pro i7-4770@3.40GHZ and 16GB Ram. I will get the model of the video card but apparantly this is a $3,000 computer. I also noticed on the Computer tech specs where it said limited Touch Support with 2 Touchpoints.
There are 3 touchscreens involved so we were pumping full 3MP cameras all 12 into a "16 screen" view into all three screens. These three screens will be in different locations and the system will grow to 16 cameras. We were using the manufacturers software which can manage 1100 cameras. If manufacturer name is necessary but it is a tier 1 camera manufacturer.
I think it is a PC juice problem as there is no way it can handle all this video output.
Most likely suggest they create a lower level profile stream for this type of live viewing I know they will BALK at that suggestion.
This is what I am researching now would like to hear any experience with a similiar situation.
