Indoor Security Cameras and Privacy: Where to Place Them and What the Law Says

An indoor camera can check on a pet, watch a front hall or let you keep an eye on a relative. It can also record people who do not expect it. Privacy rules for indoor cameras come down to two things: where the camera points, and whether it records sound. This guide explains both in plain terms, with the main rules in the United States. It is general information, not legal advice, and laws differ by state and country. It is part of our home security cameras guide.

Two kinds of rules

Security.org explains that two types of law matter most: expectation-of-privacy laws for video, and one-party or two-party consent laws for audio. Video is judged by whether the people recorded had a reasonable expectation of privacy where the camera is. Audio is judged by whether the people talking agreed to be recorded. Audio rules are tougher, so they cause more trouble.

Where not to put an indoor camera

Bathrooms. Never, including for guests and household members.
Bedrooms and changing areas. Security.org and NerdWallet both advise keeping cameras away from bedrooms, guest rooms and bathrooms. NerdWallet notes that an overnight guest has a reasonable expectation of privacy in your home.
Anywhere pointed at a neighbor's private space. If a camera can see into a neighbor's property, change the angle or use a privacy-zone feature that blocks part of the view.

Better places are shared areas that people expect to be watched: the entry hall, the area near the main door, the living room or the kitchen. See where to place security cameras for placement tips.

Audio: the part that causes legal trouble

Many cameras record sound by default. Federal law covers intercepting private conversations; NerdWallet notes that 18 U.S.C. section 2511 concerns conversations recorded when at least one person involved has consented. Many states follow a one-party rule, but some require everyone in the conversation to agree. California, for example, restricts recording confidential conversations without all parties' consent (Penal Code section 632), according to Deep Sentinel, and Guardian Protection treats Maryland as an all-party consent state for private audio. SafeHome gives a simple example: a camera that picks up a talk between you and a delivery driver in a two-party consent state may break the law unless the driver consented.

The safest approach is to turn audio off on indoor cameras unless you are sure of your state's rules. Deep Sentinel suggests exactly that for any indoor camera that might capture private conversations.

Guests, nannies and tenants

Tell people. Let household members, guests, babysitters and cleaners know where cameras are. Deep Sentinel recommends letting guests know recording equipment is present.
Short-term rentals. Yahoo reports that Airbnb banned indoor security cameras in listings from March 2024. Check any platform's rules before you install one in a rental.
Renters. Cameras inside your own unit are usually easier to justify than devices that watch shared hallways or neighbors' doors. Guardian Protection says an indoor camera inside the unit is the lowest-risk setup for renters in Maryland. Check your lease and local rules; see home security for renters and apartment security.

Set the camera up safely

Use privacy features. Privacy zones, a lens shutter and schedules that turn the camera off while you are home.
Choose storage with care. Cloud storage sends video to a company's servers; local storage keeps it with you. See local vs cloud storage for security cameras.
Lock down the account. Use a unique password, turn on two-factor authentication and keep the app and firmware updated. A hacked camera is a serious privacy breach.
Do not hide it. A visible camera is easier to defend legally and more likely to deter. Hidden cameras in private areas can be illegal.

Frequently asked questions

Is it legal to have an indoor security camera in my own home?

Generally yes, for shared areas, but not in places where people expect privacy such as bathrooms and bedrooms, and not with audio recording that violates consent laws.

Do I have to tell guests I have cameras?

It is the safest course, and in some situations it is required. Telling guests also avoids misunderstandings.

Can my camera record audio?

It can, but audio is regulated more strictly than video. Turn it off unless you are sure you have the right consent.
