I bought a D-Link DCS-2132L camera, then a Samsung HD Pro.
BOTH cameras show UNAVAILABLE after setup.
Tried repeatedly, but the damn things are as effective as a brick (a brick might be better, at least I can hit an intruder with it).
I have no choice but to return both cameras and find a reliable system. And by reliable being able to see 1 second of video before that systems breaks is infinitely more than SmartThings ever achieved.
