Are these systems going to require dynamic dns?

Yes, HikVision does require DDNS.


With any local device, there are 2 ways got get connected over WAN (Internet).

- Push service which established a virtual link. That requires a remote service (server) that keeps track of your recorders status, IP, etc.
App connects to the server, gets location of the recorder and connects you to the system. That's how C4 works (for example).

- The 2nd and more common way is using DDNS. Recorder, router or some other device pings WAN address and reports current WAN IP address to locator server. Your device points to that server, gets the actual IP address of your house, and connects to your house. Because your house only has 1 IP address, you use ports to direct traffic to different devices in your house. That's why router needs to know how/where to PORT FORWARD(ing).
