Recording Law for Voiceprints & Biometric Data in Nevada

Nevada allows you to record an in-person conversation if at least one person taking part in the chat agrees. That rule is set out in NRS 200.650, which governs surreptitious recording of in-person conversations via a listening device. The catch: the statute never defines what makes a conversation “private” or when a recording counts as “surreptitious,” and no Nevada appellate decision construes either term. The Nevada Supreme Court in Abid v. Abid, 133 Nev. 770, 406 P.3d 476 (2017) expressly declined to reach the question, so whether your recording stays legal depends on the facts—loud public dispute versus a hushed meeting, for example. For phone calls, the rule is stricter. NRS 200.620 treats every phone call as a “wire communication” and requires one party’s consent plus either prior compliance with the NRS 179.410–515 court-order process or a qualifying emergency followed by 72-hour post-hoc judicial ratification. The Nevada Supreme Court held in Lane v. Allstate Ins. Co., 114 Nev. 1176, 969 P.2d 938 (1998) that NRS 200.620 lacks the one-party-consent language found in NRS 200.650, effectively making it an all-party-consent rule for phone calls. Ignore the all-party rule on a phone call and you risk a Category D felony plus a civil lawsuit under NRS 200.690.

Nevada has no standalone biometric-privacy statute; voiceprints are protected only when they qualify as “biometric data” under the Consumer Health Data Privacy chapter (NRS 603A.400–603A.550), enacted as SB 370 (2023) and effective March 31, 2024. Biometric data is defined to expressly include voiceprints under NRS 603A.415, but the operative duties attach only when that biometric data qualifies as “consumer health data” under NRS 603A.430—i.e., data a “regulated entity” uses to identify a consumer’s past, present, or future health status. If your voice-ID feature captures a voiceprint solely to distinguish the wearer from bystanders and not to infer or track health status, it likely falls outside the chapter’s scope. When the law applies, collection requires affirmative, voluntary consumer consent or necessity to provide a requested product or service; the consent request must disclose categories of data collected, purpose and manner of use, and (if data is shared) categories of recipients and how to withdraw consent; and consumers may request deletion within 30 days of authenticating the request. HIPAA-covered entities, GLBA financial institutions, and several other categories are exempt. Enforcement is handled by the Attorney General through deceptive-trade-practice claims under NRS 603A.550, which expressly states the chapter does not create a private right of action.

NRS 171.1233 (added to NRS by 2020, 32nd Special Session, ch. 68) expressly protects the right of a person not under arrest or in custody to record “law enforcement activity” (any activity by a peace officer acting under color of law), and bars officers from interfering with, threatening over, stopping or searching because of, or unlawfully seizing or destroying such a recording, so long as the recording person does not obstruct the officer or otherwise break the law; a person under arrest or in custody does not lose the right to have such recordings or equipment maintained and returned. Nevada sits in the Ninth Circuit, which has recognized a First Amendment right to record police performing official duties in public: Fordyce v. City of Seattle, 55 F.3d 436 (9th Cir. 1995); Askins v. U.S. Dep’t of Homeland Sec., 899 F.3d 1035, 1044 (9th Cir. 2018). Just don’t obstruct the officers or break other laws while you record.

Recording silent video without sound is not restricted by Nevada’s eavesdropping laws (NRS 200.610–200.690), which apply only to interception of a “wire communication” or surreptitious recording of a “private conversation” via a listening device—i.e., audio. If you add audio, the rules flip: phone calls are governed by NRS 200.620’s one-party-consent-plus-emergency/court-order structure, while in-person conversations are governed by NRS 200.650’s one-party-consent rule. The law does not define “private conversation” or “surreptitious,” so the safer move is to assume the stricter standard unless the facts clearly show otherwise.

Imagine you’re wearing a smartglasses device and a heated argument breaks out on the sidewalk outside a Las Vegas casino. The voices are loud, passersby can hear, and no one huddles, steps away from others, lowers their voice, or uses a partition. Under Nevada’s rules, this exchange is unlikely to be a “private conversation,” so recording it would not trigger NRS 200.650’s consent requirement. If you later use that audio to create a voiceprint for identification, check whether the voiceprint is tied to health data; if not, the biometric chapter probably doesn’t apply. This is a hypothetical example—your real situation may differ.

Break Nevada’s phone-call rule and you could face a Category D felony under NRS 200.690 and a civil lawsuit for liquidated and punitive damages plus attorney’s fees. For biometric data collected without proper consent, enforcement is handled by the Attorney General through deceptive-trade-practice claims under NRS 598.0903–598.0999, not private lawsuits. Police-interference claims under NRS 171.1233 are civil rights actions that can include injunctions and damages.

Nevada’s eavesdropping chapter is not the only law that can restrict recording. NRS 200.604 criminalizes covert photo or video capture of a person’s intimate or private body areas without consent in circumstances carrying a reasonable expectation of privacy, such as upskirting or filming in bathrooms; this statute does not apply to filming a public dispute or police encounter. Separate provisions also bar “peering” into private areas (NRS 200.603) and protect law-enforcement recordings (NRS 171.1233). These narrower statutes heighten protection in specific contexts beyond the general rules in NRS 200.620 and NRS 200.650.
