Yep, I definitely would, no hesitation... it would put my mind at ease big time.

Like Lime said, it's not about not trusting a person, but not knowing them at all.

I guess I would let them know there were cameras.. although the thought occurs that if they didn't know, then it would really be a case of 'what you see is what you get' - good and bad.

And also - we were in a situation once where one of our children made accusations against someone we did know. So sometimes, knowing a person isn't knowing them.
