Need 7 IP inputs, 1 analog input. Upgrading system in which original installer ran a mix of cat5, rg6/16/2, and premade cables that come with cheap systems. I can replace the premade but no way to replace the RG6, so either need something with 7 IP inputs and one analog or will just get a 8 channel NVR and a 4 channel DVR. As far as use on the app, it would work as one system. Have to check out Brent's suggestion still to see if it does what we need. Ed's is the opposite of what I need.
