Hi there and welcome
The computer is not involved at all, it is directly from the internet, via the router to the DVR. This is for all devices including the cell phone.
You use the computer to set up the port forwarding but nothing further.
If you would like any additional information or assistance, please do not hesitate to let me know.
Else if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
