By installing wireless nanny cams in your home, you will know all the activities that go on in your home when you are not around. You will know it if the nanny is neglecting or mistreating your children, and you will know it too if your children are misbehaving and making things extra difficult for the nanny. Since the nanny cams are wireless and properly hidden, your nanny will have no idea that her actions are being recorded, and she will not try to be superficially nice to impress you.
