I am getting a network of 12 cameras linked to a DVR. Need to connect that to a router, and the guys doing the installation said I need a static IP. I don't know much about this stuff [obviously].
@deepakvrao You don't necessarily require a static IP. Like some people already suggested, a free account with no-ip.com or any other similar dynamic DNS providers will get you all sorted. Which router is everything being connected to? Most routers have a dynamic DNS client built in to them, so you can check which ones your router supports and use one of those services. After that, you can just use whatever domain name you get from the dynamic DNS provider instead of using the static IP to access the cameras.

Static IP is not needed - you just need a router with Dynamic DNS support. Teamviewer would mean that you need a computer ON with the camera's running + teamviewer video (IMO) aint that great.
