Good app, but still can improve a little bit

Its a good app, better than Dlink official app when I use my Dlink DCS-5020L.

However, I only can choose 502x model, and mic cant work 2-way mode. It will be better if it can like owls app that can setup one device with internal and external IP and port, then it can switch ip automatically. Right now, I must setup two devices, one is called internal, another is called external.
