The Federal Framework
Federal law sets the floor. The Electronic Communications Privacy Act (ECPA) and the Video Voyeurism Prevention Act of 2004 prohibit recording individuals in areas where they have a reasonable expectation of privacy without their consent. Bathrooms, changing rooms, and hotel rooms are universally protected. Penalties include up to one year in federal prison for first-time offenses, two years for repeat violations.
One-Party vs. All-Party Consent for Audio
Security cameras with audio recording are subject to wiretapping and eavesdropping laws that differ significantly by state.
One-party consent states (the majority of US states): Alabama, Alaska, Arizona, Arkansas, Colorado, Georgia, Hawaii, Idaho, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Minnesota, Missouri, Montana, Nebraska, New Jersey, New Mexico, New York, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, Virginia, West Virginia, Wisconsin, and Wyoming. In these states, one person in the conversation must consent to recording.
All-party consent states: California, Connecticut, Delaware, Florida, Illinois, Maryland, Massachusetts, Michigan, New Hampshire, Pennsylvania, and Washington. ALL parties must consent to audio recording. Security cameras that pick up conversations in these states may require clear disclosure to all parties.
Key State Laws
California has the strongest protections. California Penal Code 632 requires all-party consent for confidential communications. Civil Code 1708.8 prohibits constructive invasion of privacy — using technology to capture images or recordings that couldn't be captured without the technology even from public spaces. Penalties reach up to $5,000 per violation plus punitive damages. Hidden cameras in private areas can result in up to one year in county jail plus a $2,500 fine per offense.
Florida's Security Surveillance Act (Section 810.145) prohibits observation of persons in private places without consent. First offense is a misdemeanor; repeat violations or cases involving a minor are felonies. Two-party consent for audio is required. Distributing recordings from illegal surveillance is a separate felony.
Texas's Invasive Visual Recording law (Penal Code 21.15) prohibits capturing images of private areas without consent. One-party consent for audio. Cameras on your own property filming visible areas of a neighbor's property are generally legal.
