the camera is only a machine. Remember that the camera has blind spots. If your helper wants to avoid the camera, she simply needs to do bad things beyond the viewing range of the camera. If you trust the camera and not the human, then you will never trust your maid. If you cannot trust your maid with your baby, like the other posters say, you should find someone you trust, or maybe even forget about having a helper since you start from a position of mistrust. Many people ask me why I don't instal a camera to spy on my maid, and I say, if my maid is hurting my baby, I am positive that my baby will cry and refuse to stay with the maid! Be a good employer, but do not be too lenient, the same as you are an employee in your day job. Not everyone will agree with me, but this is my two cents worth.
