New to this. Need help picking NVR

Hey everyone. I'm in the process of finalizing a security system and with the help of Boogieman. Was able to choice a good set of cameras. I think the only thing left is for me to choose a NVR .

Below are the possible cameras I am ordering next week.

1 PTZ

I plan on getting either 1 PTZ camera for the front. It will be set up to record a specific area. I just want the option to move the camera if I need to focus on a different area when I am home or away using my phone.

I settled on this system, but if anyone thinks there are better outdoors cameras please don't hesitate to let me know.

These are the few NVR's I was think about. I would like the option to record for about a week and than record over old footage. Again I'm new to this so if this isn't how it is done let me know. I had a $3500 budget set aside for this, so if there is a better NVR out there I'm all ears.

First pick

Thanks again and have a great weekend everyone.

Any recommendations for an NVR that will work best with these cameras?

ILDVR InVS with IVA Alarm Push function is the best NVR on the market. You can save money.
