Are hidden cameras legal in Airbnb properties in the US?

In the US, it's generally illegal to place cameras in areas where privacy is expected, such as bathrooms or changing rooms. However, the transcript indicates that in recent years, more Airbnb hosts have begun using cameras to protect their properties from damage. While hosts may have legitimate reasons for surveillance, they cannot place cameras in private spaces. The increasing use of cameras in rental properties has created a need for tools like hidden camera detectors to help guests ensure their privacy is protected during their stay.
