How to get 2C Pro 2K streaming via RTSP to Synology Surveillance station

So, I’ve been reading up on getting the 2C Pro working with the Synology Synology Surveillance station. http://community.anker.com/t/how-to-setup-rtsp-on-eufycam-to-stream-video-to-your-compatible-nas/64833

How do you enable 2K recording to NAS?. I’m only seeing references to 1080p recording to NAS.

RTSP is limited to 1080p on all Eufy gear.
