Illinois Smart Glasses Recording Laws: Audio, BIPA & Consent

You can legally wear smart glasses in Illinois, but two independent statutes create serious legal exposure. Illinois is an all-party consent state: recording the audio of a private conversation with smart glasses requires everyone's consent under 720 ILCS 5/14-2. Illinois also has the nation's strongest biometric privacy law, BIPA (740 ILCS 14), which requires written consent before any app captures your face geometry and gives individuals a private right of action for $1,000 to $5,000 per violation.

Are smart glasses legal to own and wear in Illinois?

Smart glasses are legal to purchase, own, and wear in Illinois. No Illinois statute bans the devices, classifies them as restricted surveillance equipment, or limits their sale. Devices like Meta Ray-Ban AI glasses are sold at retail and may be worn in public without any special registration or permit.

The legal questions arise not from owning the glasses but from using them. Smart glasses differ fundamentally from a phone or handheld camera because they are visually indistinguishable from ordinary eyewear. A person standing next to you has no way of knowing whether you are recording unless they notice the capture LED. That invisibility places smart glasses directly within the concern that Illinois eavesdropping law and biometric privacy law were each designed to address.

Illinois has two overlapping frameworks that reach smart-glasses use: its eavesdropping statute, which governs audio, and the Biometric Information Privacy Act (BIPA), which governs any capture of face geometry or other biometric identifiers. Illinois is unique among all fifty states because BIPA gives private citizens a direct right to sue, with statutory damages ranging from $1,000 to $5,000 per person. Both layers of law require attention from anyone using smart glasses in the state.

Recording video in public vs. private spaces

The starting point for video-only recording is the reasonable expectation of privacy doctrine established in Katz v. United States, 389 U.S. 347 (1967). People in publicly accessible spaces accept that they may be observed. A pedestrian on Michigan Avenue, a shopper in a grocery store, or a commuter on the CTA cannot reasonably claim a right not to be seen or video-recorded.

Using smart glasses to capture video in a public setting is therefore generally lawful in Illinois. The federal Wiretap Act, 18 U.S.C. § 2510, reinforces this conclusion: the Act's definition of "aural transfer" limits its reach to communications containing the human voice. Silent video recording without audio does not constitute an interception under § 2510(18), and no Illinois statute separately criminalizes video-only capture in a public space.

Private spaces change the analysis. Recording video inside a private home, medical office, law firm, or other location where individuals have a genuine expectation of privacy from visual observation can create civil liability for intrusion upon seclusion under Restatement (Second) of Torts § 652B, even without audio and even if the footage is never shared. The act of recording itself is the tortious intrusion when it would be "highly offensive to a reasonable person." Pointing smart-glasses cameras through the windows of a private residence, recording inside a private workplace office without permission, or capturing intimate scenes in a hotel room all satisfy that standard.

Illinois video law also includes the unauthorized video recording statute at 720 ILCS 5/26-4, addressed in the section below, which imposes criminal liability for recording someone without consent in specific locations.

Audio recording and Illinois's all-party consent rule

This is where the primary criminal risk lies. Illinois requires all-party consent for the audio recording of private conversations. The eavesdropping statute, 720 ILCS 5/14-2, makes it a crime to use an eavesdropping device in a surreptitious manner to record a private conversation without the consent of all parties to that conversation.

Two elements must both be present for the statute to apply. First, the recording must be surreptitious, which 720 ILCS 5/14-1(g) defines as obtained or made by stealth or deception, or executed through secrecy or concealment. Second, the conversation must be private. Under 720 ILCS 5/14-1(d), a private conversation is an oral communication in which at least one party intended privacy and circumstances objectively justified that expectation. A quiet meeting between colleagues behind a closed office door qualifies. A loud argument on a city sidewalk, audible to passersby, does not.

This version of the Illinois eavesdropping statute was enacted by Senate Bill 1342 (P.A. 098-1142), effective January 1, 2015, following companion Illinois Supreme Court decisions in People v. Clark, 2014 IL 115776, and People v. Melongo, 2014 IL 114852, both decided March 20, 2014. The prior statute was struck down as unconstitutionally overbroad because it criminalized a wide range of innocent conduct, including recording conversations that cannot be deemed private, such as a loud argument on the street, a political debate on a college quad, or yelling fans at an athletic event. The narrowed statute cured those defects by adding the "surreptitiously" element and the private-conversation anchor. Open recording of public events, police activity in public, and government proceedings is not covered by the current statute.

Smart glasses create a specific compliance problem under 720 ILCS 5/14-2. Unlike a raised phone, which provides a visible signal that recording may be occurring, smart glasses are designed to look like ordinary eyewear. Wearing functioning recording glasses into a business meeting, a doctor's appointment, or a one-on-one workplace conversation and capturing audio without disclosing the recording to all participants is the paradigm case of surreptitious recording of a private conversation. The statute's "surreptitiously" requirement is met precisely because the glasses look like glasses.

The federal one-party consent exception under 18 U.S.C. § 2511(2)(d) allows a participant in a conversation to record it without notifying the others at the federal level. But that exception explicitly yields to more restrictive state laws, and Illinois's all-party requirement is more restrictive. Any person recording in Illinois must comply with Illinois law regardless of where the other participants are located.

Where recording is absolutely barred: voyeurism and private spaces

Some locations carry felony exposure for recording without consent. 720 ILCS 5/26-4 is Illinois's unauthorized video recording statute. It makes it unlawful to knowingly make a video record or transmit live video of another person without that person's consent in a restroom, tanning bed, tanning salon, locker room, changing room, or hotel bedroom, or in that person's own residence. It also bars recording another person's intimate parts without consent. The statute applies to any device, including recording glasses.

Making such a recording in violation of 720 ILCS 5/26-4 is a Class 4 felony, carrying 1 to 3 years imprisonment. The offense is a Class 3 felony, carrying 2 to 5 years, when the victim is under eighteen years of age or when the offender is a registered sex offender, whether or not it is a first offense. A conviction can also trigger sex offender registration requirements.

Smart glasses are particularly problematic in the context of this statute. Because they look like ordinary eyewear, the wearer can enter a space without detection. The statute does not require proof that a recording was shared or published. Making the recording or transmitting live video without consent in a covered location is itself the offense. The federal Video Voyeurism Prevention Act, 18 U.S.C. § 1801, provides a parallel floor on federal property; 720 ILCS 5/26-4 extends equivalent protection to all locations in Illinois.

Never wear smart glasses that have recording capability active in any restroom, locker room, changing area, or private residential space in Illinois. The felony exposure is immediate, and a claim of consent that cannot be proven is a poor defense.

Facial recognition and BIPA: Illinois's unique biometric exposure

This is where Illinois stands entirely apart from every other state in the country. The Biometric Information Privacy Act, 740 ILCS 14, enacted in 2008 and unique in granting individuals a private right of action, is the most consequential legal framework a smart-glasses user faces anywhere in the United States.

What BIPA protects. Section 10 of BIPA defines "biometric identifier" to include retina or iris scans, fingerprints, voiceprints, and scans of hand or face geometry. "Biometric information" means any information derived from a biometric identifier that is used to identify a person. Facial geometry, the data extracted from a face scan to identify or verify an individual's identity, is squarely covered. Unlike a Social Security number or a password, a facial geometry scan cannot be changed if compromised; the permanent nature of biometric data is the explicit reason the legislature created stronger protections for it.

What BIPA requires before collection. Section 15 of BIPA imposes three obligations on any private entity that collects or stores biometric data. The entity must: (a) develop and follow a written policy governing the retention and destruction of biometric data; (b) inform the person in writing that biometric data is being collected, explain the specific purpose, and disclose how long the data will be stored; and (c) receive a written release from the individual before any collection or storage occurs. All three obligations must be satisfied before the first scan takes place. There is no cure-after-the-fact option under BIPA.

How BIPA applies to smart glasses. A smart-glasses wearer who uses a facial-recognition application to identify passersby is collecting biometric identifiers under BIPA at the moment of each face scan. This is not a theoretical risk. In October 2024, Harvard students AnhPhu Nguyen and Caine Ardayfio demonstrated the "I-XRAY" project: by pairing Meta Ray-Ban glasses with PimEyes (a third-party reverse facial-recognition engine) and AI analysis tools, they identified strangers on the street in real time and retrieved names, home addresses, and partial Social Security numbers within minutes of capturing a face. Meta provided only the camera hardware; the identification layer was entirely third-party software. But the demonstration proved the technical feasibility of passive, covert biometric identification via consumer smart glasses, and it illustrated exactly the conduct BIPA was designed to prevent.

Every person whose face geometry is scanned without prior written consent is a separate BIPA violation. Because BIPA has no de minimis threshold, walking through a crowd while running a facial-recognition app could generate dozens of independent statutory claims simultaneously.

The private right of action and damages. Section 20 of BIPA gives any individual whose biometric data was collected or used in violation of the Act a direct cause of action in Illinois courts. Statutory damages are:

• $1,000 per negligent violation, or actual damages if greater
• $5,000 per intentional or reckless violation, or actual damages if greater
• Attorney fees, costs, and injunctive relief in addition to damages

A 2024 amendment, Public Act 103-769, addressed the issue of "per scan" damages in cases involving repeated collection of the same person's biometric data. Under P.A. 103-769 (740 ILCS 14/20), when the same entity repeatedly collects or discloses the same individual's biometric identifier or biometric information from that same person using the same method of collection, that counts as a single violation rather than one violation per scan. Switching to a different collection method for the same person, such as moving from a static photo scan to continuous live video capture, is not automatically covered by this single-violation rule. However, each distinct person whose face geometry is scanned without consent remains a separate violation. If twenty people walk past a smart-glasses wearer running a facial-recognition app and twenty faces are scanned without written consent, that is twenty separate violations, potentially $100,000 in statutory damages at the intentional level.

BIPA's litigation track record. BIPA has produced the largest biometric-privacy settlements in United States history, including Meta ($650 million in the Facebook facial-recognition class action), Google ($100 million), TikTok ($92 million), and Clearview AI ($51.75 million). These cases involved corporate defendants using automated systems at scale, but the statutory text contains no exemption for individual users or small-scale collection. Any private entity, including an individual acting in a commercial context, that captures face geometry without written consent is within the statute's reach.

Practical implications for smart-glasses users in Illinois. The clearest safe approach is to disable any facial-recognition application before wearing smart glasses in any setting where identifiable individuals are present. If facial-recognition functionality is a necessary part of an intended use, BIPA's written-consent requirement must be satisfied before any scan takes place, which as a practical matter means obtaining written consent from every individual whose face may be captured. That requirement is incompatible with using facial-recognition apps in any crowd or semi-public setting.

Penalties for recording violations in Illinois

Illinois combines criminal penalties for eavesdropping with civil liability that runs in parallel. A single unlawful smart-glasses recording session can produce exposure under both simultaneously.

Under 720 ILCS 5/14-4, eavesdropping penalties are:

• First offense: Class 4 felony, 1 to 3 years imprisonment, fine up to $25,000
• Subsequent offense: Class 3 felony, 2 to 5 years imprisonment, fine up to $25,000
• Corporate defendants: same imprisonment ranges, fines up to $50,000

Enhanced penalties under 720 ILCS 5/14-4(b) apply when the conversation intercepted involves a law enforcement officer, State's Attorney or assistant, the Attorney General or an assistant, or a judge performing official duties; those offenses are Class 3 felonies, or Class 2 felonies for a second or subsequent offense.

On the civil side, 720 ILCS 5/14-6 allows any person whose private conversation was unlawfully recorded to seek an injunction, actual damages, and punitive damages. Third parties who knowingly assisted in the eavesdropping, including landlords, carriers, or building operators who permitted the recording to occur, face matching civil exposure.

For BIPA violations, the separate civil damages of $1,000 to $5,000 per person apply on top of any eavesdropping remedies if both statutes are violated in the same recording session. A smart-glasses recording that captures both private audio and facial geometry without consent triggers both frameworks simultaneously.

Illinois also generally bars illegally obtained recordings from use as evidence in civil, criminal, and administrative proceedings under 720 ILCS 5/14-5. The exceptions are narrow: relevant portions may be admitted in a criminal trial or grand jury proceeding against the person charged with eavesdropping, and the evidence may be admitted when all parties to the conversation consent. The recorder faces criminal and civil consequences and generally derives no procedural benefit from the recording.

Practical tips for smart-glasses users in Illinois

Following these practices substantially reduces legal exposure under Illinois law.

Disable facial-recognition apps before use in public. This is the single most important step for Illinois compliance. No Illinois exemption exists for "casual" or non-commercial face scanning. Any app that captures or processes facial geometry of identifiable individuals without written consent violates BIPA. Disable the app before the glasses go on; do not rely on turning it off when you see someone you recognize.

Announce audio recording before starting in any private setting. In any setting where participants might have a reasonable expectation of privacy in their spoken words, say clearly before you start: "I am recording this conversation." Verbal disclosure and continued participation by the other parties establishes consent under 720 ILCS 5/14-2. The statute requires only that the recording not be surreptitious; announced recording with no objection satisfies that requirement.

Let the capture LED shine. Meta's guidance states that users should let the capture LED illuminate and not cover it. In Illinois, covering the LED while recording a private conversation removes the only external indicator that recording is occurring, which strengthens a finding of surreptitious recording under 720 ILCS 5/14-2. Keep the LED visible and unobstructed at all times.

Obtain written consent for sensitive conversations. For business meetings, legal or medical consultations, or any conversation with professional significance, get written confirmation that all participants consent before recording begins. A text or email exchange before the meeting creates a record.

Switch to video-only or mute audio in semi-private settings. Many smart glasses models allow video-only recording or offer a microphone mute function. In Illinois, the eavesdropping statute reaches only audio of private conversations. Switching to video-only in any semi-private setting eliminates 720 ILCS 5/14-2 exposure while preserving video capture.

Never activate recording glasses in restrooms, locker rooms, or private residential spaces. The voyeurism statute at 720 ILCS 5/26-4 makes recording someone without consent in these spaces a Class 4 felony. The felony attaches to the act of recording, not to any subsequent disclosure.

Frequently Asked Questions

Are smart glasses legal to use in Illinois?

Yes, smart glasses are legal to own and wear in Illinois. No statute bans the device. The legal risk is in how you use them: recording video in public is generally lawful, but recording the audio of a private conversation without all parties' consent violates 720 ILCS 5/14-2 and can result in felony charges and civil liability. Using facial-recognition apps without written consent from each scanned individual also violates BIPA and can result in statutory damages of $1,000 to $5,000 per person.

Do I need consent to record audio with smart glasses in Illinois?

Yes. Illinois requires all-party consent under 720 ILCS 5/14-2 for recording a private conversation. A first offense is a Class 4 felony carrying 1 to 3 years imprisonment and a fine up to $25,000. You must ensure all participants in a private conversation know they are being recorded and do not object before audio capture begins.

What is BIPA and does it apply to smart glasses?

BIPA is the Illinois Biometric Information Privacy Act, 740 ILCS 14. It requires private entities to obtain written consent before collecting biometric identifiers, which include scans of face geometry. A smart-glasses user who runs a facial-recognition app that scans people's faces without their written consent violates BIPA. Statutory damages are $1,000 per negligent violation or $5,000 per intentional violation per person, plus attorney fees. Every individual whose face is scanned without consent is a separate violation.

Can I be sued individually under BIPA for using smart glasses?

Yes. BIPA's private right of action in Section 20 applies to any private entity that violates the Act, not only large corporations. An individual who uses a facial-recognition app with smart glasses to scan identifiable people without written consent is a private entity acting in violation of BIPA. That person is directly exposed to statutory damages of up to $5,000 per intentional violation per person, plus attorney fees.

What was the I-XRAY demonstration and why does it matter in Illinois?

In October 2024, Harvard students showed that Meta Ray-Ban glasses paired with the third-party facial-recognition engine PimEyes could identify strangers in real time and retrieve home addresses and partial Social Security numbers within minutes. Meta provided only the camera hardware. The demonstration illustrated the practical feasibility of passive biometric identification via smart glasses. In Illinois, replicating this technique without written consent from each person identified would violate BIPA and create statutory damages of up to $5,000 per person identified.

Do I need consent to record video with smart glasses in Illinois?

For video-only capture in a public space where people have no reasonable expectation of privacy, consent is generally not required under Illinois law. However, recording video in private spaces can create civil liability for intrusion upon seclusion even without audio, and recording in restrooms, locker rooms, or private residential spaces without the person's consent is a Class 4 felony under 720 ILCS 5/26-4.

What happens if I secretly record a private conversation in Illinois?

Secretly recording a private conversation in Illinois is a Class 4 felony under 720 ILCS 5/14-2 for a first offense, carrying 1 to 3 years imprisonment and a fine of up to $25,000. A subsequent offense is a Class 3 felony carrying 2 to 5 years. The victim can also sue for an injunction, actual damages, and punitive damages under 720 ILCS 5/14-6. The recording is generally inadmissible as evidence, although 720 ILCS 5/14-5 allows it in a criminal case against the person charged with eavesdropping or when all parties consent to its admission.

Can I cover the recording LED on my smart glasses in Illinois?

Covering the LED is not separately criminalized in Illinois as of June 2026. However, covering the LED while recording a private conversation removes the only external signal that recording is occurring, which strongly supports a finding that the recording was surreptitious under 720 ILCS 5/14-2. Surreptitious recording of a private conversation is a Class 4 felony. Keep the LED unobstructed at all times.

Are smart glasses legal in a two-party consent state like Illinois?

Smart glasses are legal to own and wear in Illinois. Recording video in public is generally lawful. Recording audio of a private conversation without all participants' knowledge and consent is a Class 4 felony under 720 ILCS 5/14-2. Using facial-recognition apps without written consent from each scanned individual separately violates BIPA with damages of $1,000 to $5,000 per person. Illinois combines the audio-consent requirements of an all-party state with the nation's strictest biometric law.
