In almost every situation, no — someone cannot legally put hidden cameras in your house, and the person who installed one can face criminal charges, a civil lawsuit, or both. The details depend on where in the home the camera sits, whether it captures audio, and who placed it. Bedrooms, bathrooms, and other private spaces are off-limits everywhere in the United States. Common areas are more complicated, and audio recording brings its own set of stricter laws on top of the video rules.
When a Hidden Camera Is Illegal
Courts decide surveillance cases using a single test: did the person being recorded have a reasonable expectation of privacy in that space? The test has two parts. The person must actually expect privacy there, and that expectation must be one society considers reasonable.
Bedrooms, bathrooms, changing areas, and guest rooms clear that bar without argument. Recording someone in any of those spaces without their knowledge is illegal in every state, regardless of who owns the property. Depending on the jurisdiction, the offense can be a misdemeanor carrying up to a year in jail or a felony with two to ten years in prison and fines reaching $10,000 or more. Repeat offenses and recordings involving minors escalate the charges. Distributing the footage is often a separate and more serious felony.
Living rooms, kitchens, and hallways are the gray zone. The expectation of privacy is lower in shared or common areas, and whether a camera is legal there depends on who installed it and why. A homeowner recording their own living room with a video-only device stands on much firmer ground than a landlord, an ex, or a houseguest doing the same thing. Even then, adding audio changes the analysis completely.
One boundary worth naming: there is a federal video voyeurism statute, but it applies only on federal property such as military bases, national parks, and federal buildings.1Office of the Law Revision Counsel. 18 USC 1801 – Video Voyeurism Hidden cameras inside private homes are handled by state law.
Audio Recording Is a Separate, Stricter Rule
Federal wiretapping law makes it a crime to intentionally intercept someone’s oral communications without authorization, punishable by up to five years in prison, and it lets the person recorded sue for damages.2Office of the Law Revision Counsel. 18 USC 2511 – Interception and Disclosure of Wire, Oral, or Electronic Communications Prohibited Federal law follows a one-party consent rule: if you are part of the conversation, or one participant agreed, recording is not a federal crime. Most states follow the same approach.
Roughly a dozen states go further and require everyone in the conversation to consent. California, Florida, Illinois, Maryland, Massachusetts, Pennsylvania, and Washington are among the best-known all-party consent states. Oregon and Nevada apply different rules for in-person versus telephone conversations. In an all-party consent state, a hidden camera that captures audio in your home is almost certainly illegal no matter where it sits.
When people in different states are on the same recording, the safer practice is to follow whichever state has the stricter rule.
Who Placed the Camera Matters
A Landlord
A landlord cannot put any surveillance device inside your rental unit. Once the lease is signed, you have a reasonable expectation of privacy in the space, and the landlord’s ownership does not override it. Cameras inside the unit without your knowledge or consent are illegal in virtually every jurisdiction.
Landlords of multi-unit buildings can install cameras in genuinely common areas like lobbies, parking garages, and building entrances. Some states require them to post visible notices. If those cameras also record audio, the landlord has to comply with the applicable wiretapping consent laws.
A Spouse or Partner
Sharing a home does not give either person unlimited surveillance rights over the other. A co-resident who puts a video-only camera in a shared common area like the kitchen sits in a legal gray zone that varies by state. Recording in a bedroom, bathroom, or any other space where a partner would reasonably expect privacy is illegal.
This comes up often in divorce and custody disputes. Recordings obtained illegally are frequently inadmissible in court, and the spouse who made them can face criminal charges on top of the family law case. If the camera captures audio, all-party consent rules apply. Hidden cameras planted by a current or former partner can also amount to stalking; most states include electronic surveillance in their stalking statutes, and victims can seek protective orders that specifically prohibit monitoring.
A Nanny or Caregiver Situation
Parents can legally use video-only cameras to monitor caregivers in common areas of their own home without the caregiver’s knowledge or consent. Two limits apply. If the caregiver lives in the home, their designated private space (typically a bedroom and bathroom) carries a reasonable expectation of privacy, and cameras there are illegal. And if the nanny cam records audio, state wiretapping law controls. In an all-party consent state, secretly recording a caregiver’s conversations can be a crime even though the video is fine.
A Short-Term Rental Host
Airbnb banned all indoor security cameras in listings worldwide as of April 30, 2024, whether the device is on or off. Outdoor cameras are still allowed but must be disclosed in the listing and cannot monitor spaces like hot tubs or saunas.3Airbnb Help Center. Restrictions on Security Cameras and Other Devices in Homes Platform policy aside, guests carry the same reasonable expectation of privacy as anyone else, so a host who secretly records guests in bedrooms or bathrooms faces the same voyeurism charges as any other offender.
How to Find a Hidden Camera
You can search a room reasonably well without specialized equipment.
Look, Then Look Again in the Dark
Start with the common hiding spots: smoke detectors, clocks, charging adapters, picture frames, air purifiers, and anything that looks out of place or newly installed. Watch for tiny pinholes in objects facing the room. Then close the curtains, turn off the lights, and slowly sweep a bright flashlight across shelves, vents, and corners. Camera lenses reflect light and produce a small glint that ordinary surfaces do not. While the room is dark, also watch for faint red or green LED indicators.
Use Your Phone to Spot Infrared
Many hidden cameras use infrared LEDs for night vision, and a phone’s front-facing camera can often pick up infrared that your eyes cannot see. Turn off the lights, open the camera app on the front camera (which typically lacks an IR filter), and scan the room slowly. Infrared emitters show up as small glowing dots, usually purple or white.
Check for Wireless Signals
Wireless cameras transmit on the same 2.4 GHz and 5 GHz bands as Wi-Fi. An RF detector costs around $20 to $50 online. Turn off your known wireless devices first, then sweep the room; a strong signal coming from an unexpected object like a wall clock or power strip is worth investigating. You can also open your router’s connected devices list or use a network scanning app and look for unfamiliar devices, especially any with manufacturer names tied to cameras. This will not catch cameras on a separate network or ones that store footage locally on an SD card.
What to Do If You Find One
Do not pull it down or destroy it. The device is evidence. It may hold fingerprints, stored footage, or metadata that identifies who placed it and when, and tampering with it can compromise an investigation.
Photograph and video-record the camera exactly where it sits, capturing its location, angle, and any wiring. Write down who has had access to your home recently, including anyone with keys, access codes, or unsupervised entry. If you feel unsafe or suspect the camera is tied to stalking or domestic violence, leave and call 911.
From a safe location, file a report with local police. Officers can collect the device properly, preserve the chain of custody, and open a criminal investigation. Your written timeline of when you noticed anything unusual, paired with the access history, often decides both criminal accountability and civil remedies.
Suing the Person Who Planted It
Beyond criminal charges, the person who placed the camera can be sued in civil court for invasion of privacy. Successful claims can recover compensatory damages for emotional distress, therapy costs, lost wages, and other harms. Courts may award punitive damages when the conduct was especially egregious.
If the camera captured audio in violation of wiretapping law, the federal wiretap statute provides its own civil remedy for actual damages, statutory damages, punitive damages, and attorney’s fees.2Office of the Law Revision Counsel. 18 USC 2511 – Interception and Disclosure of Wire, Oral, or Electronic Communications Prohibited That claim sits on top of any state law claims.
A privacy attorney can weigh both the criminal and civil sides. Many offer free initial consultations, and in cases with strong evidence, some work on contingency.
