You don't need a static WAN IP if you're using the HIK-CONNECT app. If you're using the IVMS-4500 app then you need to set up DDNS and Port Forwarding. I've done both on dozens of occasions without issue.
Again, you don't HAVE to setup ddns or HIK-Connect. You just have to setup port forwarding and then use the WAN IP in the app. Obviously this is not recommended as the WAN IP can change at any time. But it works and I prefer to set it up first using the WAN IP to test, then add DDNS settings.
