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 Arizona, it is generally legal to install video cameras in your home for the purpose of monitoring a babysitter or nanny. This does not require the consent of the person being recorded, as long as the recording is video only and does not capture audio. However, it is illegal to place cameras in private areas such as bathrooms or a live-in nanny's bedroom, where there is a reasonable expectation of privacy. Arizona is not a two-party consent state when it comes to recording conversations; it operates under a one-party consent law. This means that audio recording is legal as long as one party to the conversation consents to the recording. Therefore, in Arizona, you can legally record audio with a camera or other device in your home if you are a party to the conversation and consent to the recording. However, it would be illegal to record audio without the consent of at least one person involved in the conversation, which means you cannot secretly record the babysitter or nanny's conversations without their knowledge if you are not a participant in those conversations.
