need expert help setting up cctv cameras , thro sky router
You only need to do this if you want to access the cameras over the internet.
If not then you do not need to do any port forwarding on the router.
Create a service cctv
open the required ports
typically rtsp port 554
your cctv system should be able to provide you with the correct information on what ports to open.
If you have an NVR then you would normally open the NVR ports and see all from that IP address.
Hope that helps as a guide.
