had a decent stand-alone kit that did all that (minus an HDD that you simply install). While it's IR is a bit short sighted (they all look the same illuminated at night from 15' up), it's pretty good video over all. Even with the weak IR; In the end I'd rather have lights come on and hope to scare them off instead of secretly recording the people feeling comfortable stealing my stuff.
If you go hardwired, it takes a bit of work but is possible. Lots of switches out there
dedicate part of their ports or at least bandwidth and management to home surveillance.
