Is Secret Smart-Glasses Filming a Federal Crime?
the one federal Voyeurism law was written for changing rooms, not sidewalks
The fear, and the statute that is supposed to answer it
Someone walks past wearing a pair of ordinary-looking glasses with a camera in the hinge. The assumption most people carry is that if those glasses are quietly recording, some law is being broken and there is a remedy waiting. It is a reasonable assumption. It is mostly wrong, and the reason is worth reading in the text of the one federal law that sounds like it should apply.
That law is 18 U.S.C. § 1801, the operative section of the Video Voyeurism Prevention Act of 2004. Read cold, its opening line does a lot of narrowing in a single sentence. It makes it a crime to have "the intent to capture an image of a private area of an individual without their consent" and to do so "under circumstances in which the individual has a reasonable expectation of privacy." A first read hears "capture an image of an individual." What the statute actually says is "a private area," and every other word in the section is built around that phrase.
What "a private area" means in the federal law
The Act does not leave the term to interpretation. It defines "a private area of the individual" as "the naked or undergarment clad genitals, pubic area, buttocks, or female breast," and it defines a woman's breast down to the areola. The reasonable-expectation clause is written the same way: it covers circumstances where a person "would believe that he or she could disrobe in privacy," or where they would believe a private area "would not be visible to the public, regardless of whether that person is in a public or private place."
Put those definitions back into the opening sentence and the shape of the crime is clear. This is a statute about undressing, about the fitting room and the toilet stall and the camera slipped under a hem. A face on a train platform, a body on a beach in full clothing, a person walking down a street, none of it is "a private area" as the federal law defines it. The Act closes on a line that gives away its era and its target: it does not prohibit "any lawful law enforcement, correctional, or intelligence activity." It was drawn for a specific harm, and it stayed there.
The penalty tells the same story. A violation is punishable by a fine "or imprisoned not more than one year, or both," which puts it at the misdemeanour end of the federal code rather than among the serious felonies. Congress built a targeted, modest offence for a targeted harm. It did not build, and has not since built, a broad federal prohibition on recording people, and the language it chose in 2004 is the language still on the books.
The two words that keep it off the sidewalk
Even where an intimate image is involved, the federal crime reaches only a sliver of the map. Section 1801 applies solely "in the special maritime and territorial jurisdiction of the United States," and that phrase is a defined term in its own right, at 18 U.S.C. § 7.
The definition is a long list of federal places. It opens with "the high seas, any other waters within the admiralty and maritime jurisdiction of the United States and out of the jurisdiction of any particular State," and it runs on through vessels belonging to the United States or its citizens, aircraft, and lands reserved or acquired for the use of the federal government. What it is not is a city street, a shopping centre, a private gym, or almost anywhere an ordinary person spends an ordinary day. A hidden camera in a changing room on a military base is within the statute; the identical camera in a changing room at a high-street shop is a matter for state law, because the federal jurisdiction hook is missing.
So the federal video-voyeurism law is doubly confined: to intimate images, and to federal ground. Both limits have to be satisfied at once before it applies at all, which is why it is the wrong statute to reach for when the setting is a public pavement and the image is a face. The federal criminal code, read where a person would expect to find the protection, simply does not contain a general one.
Where the real lines are drawn: the states, one statute at a time
The criminal law that actually governs a hidden camera in daily life is state law, and it is not uniform. Each state writes its own voyeurism or unlawful-surveillance offence, and no two are identical in their wording or their reach. California's is a useful worked example because its text was drafted with cameras expressly in view.
California Penal Code § 647(j) makes it an offence to view, "by means of any instrumentality," the interior of "a bedroom, bathroom, changing room, fitting room, dressing room, or tanning booth, or the interior of any other area in which the occupant has a reasonable expectation of privacy," with intent to invade privacy. A second clause reaches the concealed camera used "under or through the clothing" of an identifiable person to view their body or underwear. The instrumentality list is modern; it names the camera, the camcorder, the mobile phone, the "electronic device," even the drone.
A further clause reaches secretly recording, filming or photographing another person inside one of those private rooms, so that both looking and recording are covered where the setting is private. But the setting is the whole point. Every clause turns on a reasonable expectation of privacy, and the statute anchors that to the interior of a bedroom, bathroom, changing room, fitting room, dressing room or tanning booth, "or the interior of any other area in which the occupant has a reasonable expectation of privacy."
Notice what the modern drafting did and did not change. The device list grew to catch new hardware, but the protected thing stayed the same: a private room, or a body under clothing, and a reasonable expectation of privacy. California updated the tools and left the target. The gap in the middle, a stranger's face captured in a public place, is outside § 647(j) as it is outside the federal Act, because a public place is where the expectation of privacy the statute requires is hardest to make out. That is the pattern in state after state, though the exact words and the exact list of protected places are each state's own, and only California's were read here.
Britain drew the same line, and had to pass a new law to close one gap
The point is not a quirk of American drafting. England and Wales reached the same place from the other side of the Atlantic. The Sexual Offences Act 2003 created the offence of voyeurism at section 67: observing or recording "another person doing a private act," for sexual gratification, knowing the person does not consent. "Private act" is the hinge, and it means much what the American statutes mean by a private area and a private place.
What is telling is what Parliament had to do later. When offenders used cameras to photograph up skirts in public, prosecutors found the existing voyeurism offence did not cleanly fit, because a crowded street is not a "private act" setting. So Parliament passed the Voyeurism (Offences) Act 2019, which inserted section 67A to criminalise operating equipment beneath a person's clothing to observe their genitals, buttocks or underwear. A whole new offence was needed to reach one specific act of covert filming in public. The general proposition, that filming a person in public is not itself a crime, was solid enough that the narrow exception had to be legislated by name.
The camera is the wrong thing to fear; the microphone carries the record
If the video law is this thin, why does the cluster of worry around these glasses feel so justified? Because the part of the device that carries real legal weight is not the one people look at. It is the microphone.
Silent video of a stranger in public sits mostly outside criminal law. Audio does not. Federal law at 18 U.S.C. § 2511 makes the intentional interception of an oral communication a crime, and a dozen-odd states go further and require every party to a private conversation to consent before it can be recorded. A raised phone at least announces itself; a pair of glasses recording a conversation gives the other speaker nothing to object to, which is exactly the situation those wiretap statutes were written for. The enduring legal exposure of a smart-glasses wearer runs through the sound they capture, not the pictures.
What a person filmed in public is actually left with
For the person on the other side of the lens, the honest summary is that the criminal law offers little against being filmed in public, and the remedies that exist are mostly civil and mostly narrow. Where a wearer targets one person over time, harassment law can apply, because it turns on a course of conduct rather than on the single act of recording. And in a handful of states, biometric-privacy statutes attach real money to capturing a person's faceprint without consent, which is the closest thing in the whole subject to a direct remedy for the person recorded.
That is the shape of it, stated plainly so nobody has to infer it: the law most people assume protects them from a stranger's camera in public does not exist. The statutes on the books were written for the changing room and the fitting stall, and the glasses walked past them into the street. Whether that gap should be closed is a policy question the states are only beginning to take up, and the reader watching a pair of glasses turn toward them is, for now, standing in it.
