I am a very small business owner and I have a few clients to whom sell and install security cameras. These security cameras have their own local IP address (e.g. 192.168.1.2, 192.168.1.3, etc.). Port 80 can be opened on their individual routers.
Here is my question:
I want them to be able to see their security cameras via the web by logging into a special website that keeps track of their IP address, number of cameras, etc. But if their external IP address changes (Cable and/or DSL) they will no longer be able to see their cameras over the web.
Is there a way for me to get their latest/current IP address automatically if and when it gets changed? Kind of like the DynDNS.com service but a much simpler version.
Any expert advice will be greatly appreciated.
