Recording Law for Video-Only Recording in Missouri

Missouri’s wiretapping statute, § 542.400, defines an "intercept" as the "aural acquisition" of a communication. That means the law only restricts capturing audio — it does not apply to video without sound. The related criminal section, § 542.402, prohibits intercepting wire or oral communications, but both definitions require audio to be involved. A silent video recording, even in a private setting, does not fall within these restrictions because interception under the statute is expressly tied to aural acquisition. The law does not require consent or notice for video-only recording, and there is no statute in Missouri that treats silent video differently from taking a photograph. The statute also expressly includes 'interception by one spouse of another spouse' within its definition of 'intercept,' confirming no special spousal exemption applies in the home.

Missouri has a separate invasion-of-privacy law, § 565.252, that criminalizes photographing or filming another person’s nudity or under their clothing without consent in a place where they have a reasonable expectation of privacy. This is a narrow voyeurism statute, not a general rule about video recording. It would not apply to filming a public dispute, a police interaction, or any situation where nudity is not involved. Violations are a class A misdemeanor, and can be elevated to a class E felony if the footage is distributed, involves multiple victims, or is a repeat offense.

Missouri’s wiretap law does not impose additional rules for recording in public. The statute’s privacy gate — which limits protection to communications where someone has a reasonable expectation of privacy — applies to oral communications, but not to video. Even if someone in a public place believes their conversation is private, the law does not criminalize filming them without their consent. However, the public-place exception is a reasoned extension from the statutory text with no confirmed on-point case law, so its real-world reach remains untested and should be treated with appropriate caution.

Missouri’s wiretap law does not create a special rule for recording inside someone’s home or private space. The statute explicitly closes off any implied exemption for spousal or domestic recording, meaning the same rules apply whether you are recording in a public street or a private living room. The law does not require consent or notice for video-only recording in any location. The only exception is the narrow voyeurism statute for filming nudity or under clothing without consent.

Missouri’s wiretap law does not independently criminalize recording on-duty police in public. However, the federal courts in Missouri — part of the Eighth Circuit — have not clearly established a First Amendment right to actively record police officers in public for qualified-immunity purposes. While passive observation is protected (Chestnut v. Wallace, 2020), actively filming police may not be shielded from civil liability in the same way. This means recording police is not illegal under state wiretap law, but officers could still interfere or escalate the situation, and the legal protection for doing so is unsettled.

Imagine you are attending a public protest and decide to record the scene with your phone, but you turn off the microphone so only video is captured. You film a heated argument between two people, but no audio is recorded. Under Missouri law, this is unrestricted. The wiretap statute does not apply because interception is expressly tied to aural acquisition, and the narrow voyeurism law does not apply because nudity is not involved. Even if one of the speakers later claims they expected privacy, the law does not criminalize your silent video recording.

Missouri’s wiretap statute treats wire (electronic) and oral (in-person) communications differently. For wire communications, § 542.402.2(3) gives any private citizen who is a party to the communication (or has one party’s consent) an unconditional right to record, regardless of anyone’s expectation of privacy. For oral communications, the statute’s one-party-consent exception is narrower: § 542.402.2(2) limits the oral-communication exception to persons ‘acting under law’ (i.e., law enforcement), and § 542.402.1(2) criminalizes using a device to intercept an oral communication only when the device transmits by radio or interferes with transmission. Practically, a private citizen using an ordinary non-radio recorder to capture an in-person conversation is very likely outside the statute’s criminal reach regardless of consent.
