A baby sitter is an employee. You can video tape her to your hearts content. In fact, depending you your state (like NY) you can even tape her on the crapper. No, you don't need her consent; you don't have to warn her.
I work on wall street. I'm on more cameras than the prez.
And yes, you can record her phone calls and internet traffic too. Company property ... etc.
