using i pad for webcam

needing to teach my pit bull to stay in the camper while we go out for dinner or to the pool, so I'm looking for a quick and easy way to use the ipad as a webcam so I can view it from my iphone. She stays at home without trouble all day, so we need to get her "comfortable " staying in the camper for short stints.

we had to get a "screen saver" for the screen door since she scratches at it the moment we leave. the first test session went well and she settled down in about 10 minutes. I was only gone for 15 minutes.... the next time she settled down in ~5 minutes, and I was gone for ~20 minutes.....It's nice to be able to watch and see how she reacts when we leave.

I used Facetime today and it worked well, but if you get disconnected then someone has to be there to accept the call. (haven't quite taught her that tick yet"

I downloaded the "AtHome" app for both the iphone and ipad, but it's a bit slow and has a lot of "lag" compared to using Facetime.

Nice thing about using something like facetime is that I can hear the A/C running in the background so I know we have power and the pup is cool.

Does anyone know of an app that will work well for the intended purpose?
