Hi thanks for reply not sure how the port forwarding is setup is that done on router?Hi,
Have you set up port forwarding to the NVR/Cameras properly?
Are you connecting to your external, public IP?
This is the most common reason why people fail to connect from outside their private network.
Ok, so I guess you have set up and connect to the camera using i.e. 192.168.1.108 when it works. That's your local IP and will not work to connect from the 'outside'.
Basically you have two options.
1.) Set ut port forwarding
2.) Set up an VPN
VPN is the better alternative if you want a more secure solution. It is often more complicated to set up - depending on you router.
