Thirteen states outlaw the use of surveillance cameras in dressing rooms without the consent of the occupant, while in the remaining 37 states, the use of cameras is legal to some degree, according to elephant journal. Most of these 37 states allow surveillance only if the store clearly notifies customers that they are being monitored.
The states that do not allow cameras in dressing rooms without consent are Alabama, Arkansas, California, Delaware, Georgia, Hawaii, Kansas, Maine, Michigan, Minnesota, New Hampshire, South Dakota and Utah, notes WECU Surveillance.
According to LegalMatch, video surveillance in all other states is legal only to prevent theft. If surveillance is used for other purposes, such as voyeurism, it is considered an illegal violation of privacy. In addition, some states permit using a camera to monitor dressing rooms, which is considered similar to monitoring with a two-way mirror but do not permit cameras that record activities in the room. Most states that allow video surveillance require stores to post obvious notices near the dressing room so customers know they are being monitored.
John Machay from OpposingViews.com says that many business owners believe the presence of video cameras reduces theft dramatically. For this reason, some large retailers install dummy cameras in prominent places to deter theft. These types of nonworking cameras are allowed in all states.
