What if they step into a closet or bathroom or something to abuse the baby then? I'm sure there couldn't be cameras over the toilets, for example.

"...there wouldn't be cameras over the toilets, for example".

Right. But the point is that if you put a person on notice that they are being watched, they will think twice, three times, and more before behaving in any way inappropriately, let alone abusively, while babysitting. I know of course that if they really wanted to they could take the child into a dark closet or a bathroom and harm her, but the chances would be FAR less. They simply would not feel that they could do whatever they wanted while the parents were gone.
