When I tried to add the camera as a direct child of the core I had to choose the generic IP camera template, as there still isn't one for the Y-CAM in the list. I'm not sure whatever happened to the template you created, but its not on my list. I'd have preferred to just use the camera without motion, as it already has motion detection software built in, but I was just glad to get it working so its staying as it is for now. I am going to have to adjust the refresh rate I think, as I am used to viewing it as a camera, not as a series of stills(I know its the same thing, but when you view it from a browser it refreshes itself seemlessly)
I've had mine for 18 months now, and its been faultless. The only slight gripe is that it uses an activeX script to refresh with a browser, and my old mobile phone couldn't function with this so I couldn't view it on my phone over the home wifi. Still it works great on the IPad, and now with MCE too. I like the fact that you can log into it too, mine's always been in the boy's bedroom, so I could see him when I'm working overseas. This should still work unless the router on the core fails.
