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 Delaware, it is 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 individual 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. However, Delaware is one of the states that require all parties to consent to the recording of conversations. This means that if the camera also records audio, the babysitter or nanny must give their consent to be recorded. It is advisable to obtain this consent in writing to ensure clarity and legal compliance. Unauthorized audio recording without consent may lead to legal penalties under Delaware's privacy and wiretapping laws.
