It is generally legal to install a video camera in your home to monitor a babysitter or nanny, and does not require the consent of the babysitter or nanny. But it is generally illegal to place such a camera in private places such as bathrooms or a live-in nanny’s bedroom. And in some states that require both parties to consent to the recording of a conversation, it is illegal to place a camera or other device in your home that records audio without the consent (preferably in writing) of your babysitter or nanny. These states that require two-way consent to record conversations (your consent and the babysitter or nanny’s consent) include California, Connecticut, Delaware, Florida, Hawaii, Illinois, Louisiana, Maryland, Massachusetts, Montana, Nevada, New Hampshire, Oregon, Pennsylvania, and Washington.

In Kentucky, it is generally legal to install a video camera in your home for the purposes of monitoring a babysitter or nanny. This can be done without the consent of the person being recorded, as long as the camera is placed in common areas and not in private spaces such as bathrooms or a live-in nanny's bedroom. Kentucky is a 'one-party consent' state when it comes to recording conversations, meaning that only one party involved in the conversation needs to consent to the recording. Therefore, it is legal to record audio as well as video as long as the person installing the camera is a party to the conversation or has received consent from at least one person who is. However, secretly recording audio without the consent of at least one party is illegal. It's important to note that while video recording in common areas is permissible, any recording should respect the privacy rights of individuals, and the use of recordings should comply with applicable laws regarding surveillance and privacy.
