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 Indiana, it is generally legal to install video cameras in your own home for the purposes of monitoring a babysitter or nanny. This is often done to ensure the safety and proper care of children. However, Indiana law prohibits the installation of cameras in places where there is a reasonable expectation of privacy, such as bathrooms or a live-in nanny's bedroom. Regarding audio recording, Indiana is a 'one-party consent' state, which means that only one party involved in the conversation needs to consent to the recording. Therefore, it is legal to record audio without the babysitter or nanny's consent as long as the homeowner consents to the recording. However, it is always recommended to inform any in-home employees of the presence of surveillance equipment, both video and audio, to avoid any legal complications or breaches of trust.
