Analog cameras send a video signal over coax cable to a recorder. IP cameras are small networked computers that send digital video over the same kind of cabling as your computers. That one difference drives most of the trade-offs.
For a new system, IP is almost always the better long-term choice: the image quality and flexibility are worth it, and the cabling doubles as part of your network. Analog mainly makes sense when you are reusing existing wiring or keeping costs to a bare minimum.
We are happy to talk it through and point you in the right direction, at no cost.
