What is a good indoor security camera that is easy to set up and has remote access?

I had a Mydlink and it was difficult to set up and didn't work for very long. I'm traveling and want to be able to check in on my dogs to make certain our house/pet sitter is doing their job. I want to use my iPhone to check in. Any ideas for a camera?

While a camera may elicit better service, do not actively spy on your house sitter. Do you have some kind of contractual obligation that they will spend the time you spend watching them on the camera playing with your dogs? Can you not obviously see where this will go: you'll never be happy with the fact that the sitter can't reasonably spend more than say 10% of waking time actively interacting with your dog. Even then, it's substantially more time than you'd give to your own dog.
