Did you setup port forwarding..... did you alter your firewall settings for your dvr. Or did you use a QR.
Still makes no difference just means the qr code also did local.
Which I did say in my post ... but better to setup yourself..
But you have gone off topic .... using data is your problem not local network.
So again even tho you don’t like the answer your system is going out to a p2p cloud. ..... because you did not do a safer port forwarding.... do you want to know how to fix it or not ?
I have a nvr and I just plugged the lan cable into the router...
Not sure what I am fixing now?
Yes Please. What should I have done on my router then?
