Hidden camera laws by state

Hidden camera laws in Wisconsin

The actual statute, in plain English — not a paraphrase of a paraphrase.

The statute

Wis. Stat. § 942.09 (Representations Depicting Nudity)

What it prohibits

Wisconsin bans capturing a photograph, video, or other visual "representation" depicting a person nude or partially nude, without that person’s knowledge and consent, under circumstances where the person had a reasonable expectation of privacy. The law asks whether the person reasonably expected they would not be recorded nude — not merely whether they expected the recorder specifically not to see them. It also separately criminalizes knowingly reproducing an image captured this way. Minors and people with impaired judgment are legally incapable of giving the required consent.

Penalty

Class I felony — a fine up to $10,000, imprisonment up to 3 years and 6 months, or both.

This is general public information, not legal advice, verified against the statute text linked below as of this writing — legislatures amend these laws periodically (Florida renamed its own statute in 2024). If this matters for a real situation, read the current text yourself or talk to a lawyer: https://docs.legis.wisconsin.gov/statutes/statutes/942/09. Separately, recording audio of a conversation is governed by a different law (wiretap/eavesdropping statutes, which vary by state on whether one party or all parties must consent) — this page covers image/video capture only.

If you've actually found something, the statute matters less than what you do next: read the six steps here.
