None of them have wifi built in. It's assumed that you can a cable between the NVR and the rest of your LAN.

If you don't have the option to run a cable from the NVR to your LAN, then you could get a wifi extender that has an ethernet port (something like this). Connect that to your wifi network, then plug the NVR into it, and that would get your NVR onto your LAN via wifi.
