Opinion on a Network Switch for PC-NVR

Hello,

I would appreciate your opinion on a network switch I cam considering on using for my first ever IP-Camera set up. I decided to use a PC Based option as it would allow me expand the storage space if my needs ever increased (and allow me to have reasonable budget for the time being). I am considering on using these:

Switch 1:

Switch 2:

I will probably run 12/14 cameras with ~3 being at 3mp and ~2 at 2mp and ~8 at 1.3mp. The total PoE budget for the should be enough to power the cameras, and the switch is 802.3af standard compliant.

My questions are:

1. What would be recommended bandwidth for 12/14 cameras?

2. Does the switch make difference in respect to software for PC and ONVIF capabilities of the camera?

3. I HAVE to use ONVIF cameras, correct?

4. Is blue iris the best possible solution for recording software? (I don't mind an upfront payment, however I might consider a subscription service if the benefits provide value).

5. How important is the difference between managed/smart/unmanaged switch for IP-Camera purpose?

6. Are there alternatives that you would use or recommend (short summation on why?)

7. Do the other features (securities.. etc) matter for performance?

Thank you for the feedback.

Bump!

I appreciate your opinion on a good PoE Switch and PC Software.

Thanks for your feedback!
