Ok so i have found some solutions that seem like they will work.
We currently are going with: Trendnet NVR, and sv3c poe bullet cams, reolink wire free
The cameras need to use "onvif" whatever that means.
Cheapest option:
The cheapest option I have found was just buying 4 of these. Funlux 8 cam poe system https://www.amazon.com/dp/B071YGS34L/ref=cm_sw_r_cp_apa_8bQGzbZEK9YTR
Power supply for backup, cabling supplys, 4 port kvm switch, a monitor and it seems like we could meet all regulations. It's sounds sloppy but would probly get the job done.
Cameras I liked and think would also work:
Things that are not in regulations that I think you should go with:
Super cheap 8 camera set on Amazon
