I have 14 older 4 MP cameras around the property. I want to add at least 2 more cams pointing back towards the house, and also a couple of license plate readers and overview cameras at the front of the property. It seems like I could easily build a new PC for what a 32 channel 4k NVR would cost. Any reason not to? Is it a requirement I use an Intel i7 or can I use an AMD Ryzen 7 instead? I've got an old 1050 video card in my current PC that I could swap over so I can get a new video card.
