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 Vermont, it is generally legal to install a video camera in your home for the purposes 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. Vermont is not a two-party consent state for audio recordings; it follows the federal wiretapping law, which allows for 'one-party consent.' This means that as long as one party in the conversation consents to the recording (which could be the homeowner), it is legal to record audio. However, it is illegal to place cameras in private areas where there is a reasonable expectation of privacy, such as bathrooms or a live-in nanny’s bedroom. If you wish to record audio as well as video, it is advisable to inform the babysitter or nanny and obtain their consent to avoid any legal issues.
