Hi @DBN, the reason why you cannot see the camera’s content in the dashboard is because your phone cannot access your TinyCam’s local ip address when it is not on your LAN network. When viewing the dashboard with camera media tiles included, your viewing device (phone/tablet) will try to connect the media source from the client side, and your camera’s content is never sent to SharpTools.io.
So if you’d like to view the camera media tiles on your dashboard when not on your LAN as well, you will need make your TinyCam web server external accessible. See #3 in the TinyCam Q&A for more details.
And you’d also want to make sure you have the username/password set properly, because you certainly don’t want anyone else from the world to be able to access your TinyCam server or view the videos.
---- EDIT ----
The OP is using Synology Surveillance Station, not TinyCam. But the same concept applies. The video server needs to be accessible externally, and may require things like port forwarding, DDNS, and etc.
