Nanny cam is a slang term used to describe a type of wireless or wired video surveillance system marketed to parents who want to use an in-home surveillance device to monitor their caregiver’s interactions with their children. Many video surveillance systems used as nanny cams can be hidden in small objects such as a child’s stuffed toy. There are privacy and legal issues to consider when using a nanny cam without permission being given by the caregiver to be recorded.
