Can this NVR be wirelessly connected to a home ...

Can this NVR be wirelessly connected to a home network? I want to mount it in my shop, so there will be store WiFi signal, but no ability to run a cable to the router. Cameras will have ability to run cables back to the NVR, just needed to wirelessly connect it to my home network.
Asked by: Kyle
The Dahua Technology N42B2P Lite Series 8-Channel 8MP NVR needs to be wired to the router. You cannot send the signal wirelessly.
