For cctv viewed over the internet through a router. Other than buying a static IP address, is there any way, like using a UPS to keep the IP address from changing. Would this work?
Answer:
Typically you don't need to setup up a "static" IP address. You can just choose an IP address from your system and the router will allow you to keep using that even if there is a reset of the power.
The main thing is setting up the Port Forwarding on your router for external access.
You can learn more about Port Forwarding at the link below.
