Peeping Tom laws—also known as voyeurism laws or invasion of privacy laws—generally make it illegal and a criminal offense to peek into windows or doors on private property to view a person who is fully or partially naked for the purpose of sexual desire or gratification.

Peeping Tom laws vary from state to state and some states require that the victim not realize he or she was being viewed and that the victim had a reasonable expectation of privacy (was in a place where it was reasonable to expect privacy). And some states specifically address the use of unmanned aircraft (drones), cameras, video cameras, and binoculars in connection with such peeping. Some state statutes specifically prohibit peeking into bathrooms, dressing rooms, showers, and baths. And some states characterize this criminal offense as trespassing with the intent to peer or peep.

Peeping Tom laws are located in a state’s statutes—often in the penal or criminal code.

In North Carolina, Peeping Tom laws are addressed under the state's criminal statutes, specifically in N.C. General Statute § 14-202. Peeping Tom activities are considered a Class I felony if the individual secretly peeps into a room occupied by another person without their consent for the purpose of sexual arousal or gratification. This law applies to situations where the victim has a reasonable expectation of privacy, such as in bedrooms, bathrooms, or changing rooms. Additionally, it is illegal to use photographic or recording equipment to capture images of another person in these private spaces without consent. North Carolina law also prohibits the possession of photographic images obtained in such a manner. The use of advanced technology, such as drones, for the purpose of peeping is also regulated, and individuals found using such devices to invade someone's privacy may face criminal charges. The state's approach to Peeping Tom violations can include charges of trespassing if the act involves entering onto another's property with the intent to spy or peep.
