I use two of these cameras with SmartThings and they generally work fine for photos. As @Tyler mentioned, ST does not support this on the V2 hub for live video streaming. I still use the Samsung SmartCam app for live video.
Check out Samsung SmartCam: SNH-P6410BN, SNH-E6440BN and SNH-1011ND (+WWW Digest auth) (tested and working) for a community developed device type.
I have one of my cameras set to take photos when the doorbell rings and the other when motion is detected. For the photo’s, I use the photo burst smart app from the market place.
I have been prompted to update firmware on my 1011 in the last month or so, and I have not. If you have updated, there is a possibility that the access required by the custom device type has been turned off.
If you can’t get it working, please feel free to ask questions.
