Hi, new to this forum and experimenting.

Well hello there.
I am new to this forum and just starting out with a few cameras attached to my PC in the hope of discovering what to buy.
I have figured I will need seven cameras. My first question is, as I already have an 8 port switch with 4 of the ports POE.
Should I buy a 4 port POE NVR to give me an 8 port POE capability or should I buy an 8 port POE NVR which would give me 12 POE ports and 4 non-powered ports? Even though only 3 POE cams will connect to the NVR?

you can not just add cameras to an NVR. the NVR is limited by its design. So if the NVR is designed for 8 cameras, that is all it will handle.
Most NVRs are under powered, so it is recommend to buy a bigger NVR than you think you will need. So it you think you will need 8 cameras, buy a 16 camera NVR.
It is also recommend to purchase your cameras and NVR from the same manufacture. Mixing nvr and cameras will cause a loss in advance features .
Also be careful in mixing Chinese hacked equipment and international equipment from the same manufacture, it may not work well together.

Just because an NVR said it will support 8 cameras does not mean it will support eight 4K cameras, it may only support 2 4K cameras. You have to look at the data processing rate.

I recommend looking a Blue Iris system for use as an NVR, it is excellent.

OK thanks for the suggestion guys. I have gone for an 8 port POE Annke NVR model number N48PAW. I will see how that works with my existing cameras. I have a feeling this is going to be hours of fun - not.
