Recording Law for Employers & Businesses in Illinois

Illinois makes it a crime to record an oral or electronic conversation unless every person taking part in the conversation agrees first. The core offense is set out in 720 ILCS 5/14-2 of the Illinois Criminal Code of 1961, Article 14 (Eavesdropping), which criminalizes eavesdropping on a private conversation or private electronic communication without the consent of all parties. The law defines a "private conversation" at 720 ILCS 5/14-1(d) as one where at least one party intended it to be private and the circumstances reasonably supported that expectation, and a "private electronic communication" at 720 ILCS 5/14-1(e) in parallel terms. If the conversation is private, you must get consent from every person before you record. Recording without consent is a felony under 720 ILCS 5/14-4. The same rule applies whether the conversation is face-to-face or over the phone. The law also requires the recording to be done "in a surreptitious manner" — meaning obtained or made by stealth or deception, or executed through secrecy or concealment — as defined in 720 ILCS 5/14-1(g). If recording is done openly rather than surreptitiously, the offense does not apply even if consent was not given, because the surreptitious-manner element is not satisfied. The statute does not distinguish in-person oral conversations from phone or electronic communications for consent purposes; both are governed by the same all-party consent rule, which is triggered only when the communication carries a reasonable expectation of privacy.

Illinois courts say loud arguments on the street, political debates in a park, and public interactions between police and citizens do not carry a reasonable expectation of privacy. That means recording in those settings is less likely to run afoul of the all-party consent rule. The Illinois Supreme Court made this clear in People v. Clark and People v. Melongo, both decided on March 20, 2014, which struck down the prior gateless version of the statute as unconstitutionally overbroad. The legislature restored the reasonable-expectation-of-privacy gate via P.A. 98-1142 (eff. 12/30/14), codified in 720 ILCS 5/14-1(d) and 5/14-1(e). Still, openly recording on-duty police in public is specifically protected by statute. 720 ILCS 5/14-2(e), added in 2016 by P.A. 99-352, says verbatim: "Nothing in this Article shall prohibit any individual, not a law enforcement officer, from recording a law enforcement officer in the performance of his or her duties in a public place or in circumstances in which the officer has no reasonable expectation of privacy. However, an officer may take reasonable action to maintain safety and control, secure crime scenes and accident sites, protect the integrity and confidentiality of investigations, and protect the public safety and order." The officer can take reasonable steps for safety and investigation integrity, but the recording itself is not prohibited. The surreptitious-manner element at 720 ILCS 5/14-1(g) also operates independently: even a private conversation can fall outside the offense if the recording is done openly.

Illinois only criminalizes capturing the audio of a conversation without consent. The statute defines an "eavesdropping device" at 720 ILCS 5/14-1(a) as a device used "to hear or record oral conversation or intercept, transmit, or transcribe electronic communications," and the core offense at 720 ILCS 5/14-2 criminalizes recording or overhearing "conversations" or "electronic communications" — both audio-centric concepts. If your camera records video but no audio, the eavesdropping statute does not apply. This is why silent security cameras, dashcams without microphones, and wearable cameras that capture video but not sound are generally permitted. Just be careful not to record audio at the same time, because then the all-party consent rule kicks in. Separately, a different law, 720 ILCS 5/26-4, makes it a crime to secretly record someone in a restroom, tanning booth, locker room, or changing room, regardless of audio.

If your business captures voiceprints from employees or customers, Illinois’ Biometric Information Privacy Act (BIPA) applies. BIPA is in 740 ILCS 14/1 et seq., with definitions at 740 ILCS 14/10, collection/retention requirements at 740 ILCS 14/15, a private right of action at 740 ILCS 14/20, and exemptions at 740 ILCS 14/25. It defines a voiceprint as a biometric identifier at 740 ILCS 14/10 and requires you to tell the person in writing that you are collecting it, explain why and how long you will keep it, and get their written consent before collection. You must also publish a publicly available policy on how long you keep the data and when you will destroy it, with destruction required within three years of the individual's last interaction or when the initial purpose is satisfied, whichever occurs first. Selling or profiting from the voiceprint is banned at 740 ILCS 14/15(c). BIPA gives individuals a private right of action under 740 ILCS 14/20 with statutory damages starting at $1,000 per negligent violation and $5,000 per intentional or reckless violation, plus attorneys’ fees and costs. The statute of limitations is generally five years. In 2024, Public Act 103-0769 narrowed exposure by providing that multiple collections or disclosures of the same person's biometric identifier/information using the same method now constitute a single violation (one recovery per person per method), and an electronic signature now satisfies the written-consent requirement.

Recording a private conversation without all-party consent is a felony in Illinois. Penalties range from a Class 4 felony for first offenses under 720 ILCS 5/14-4(a) up to a Class 3 felony for repeat offenses or recording certain officials under 720 ILCS 5/14-4(b). There is also a civil remedy at 720 ILCS 5/14-6: anyone whose conversation was recorded without consent can sue for damages, plus attorneys’ fees and costs. The law allows lawsuits even if the recording never harmed anyone. For biometric data like voiceprints, violations under BIPA carry statutory damages and attorneys’ fees, making compliance essential. The Illinois Supreme Court held in Cothron v. White Castle System, Inc., 2023 IL 128004 that a separate claim accrues each time biometric data is scanned/collected or transmitted/disclosed in violation of the Act, though the legislature narrowed this in 2024 so that multiple collections or disclosures of the same person's biometric identifier/information using the same method now constitute a single violation. Illinois also provides several exemptions at 720 ILCS 5/14-3, including a 15-subsection list of specific carve-outs such as recording conversations involving emergency or public-safety personnel under certain conditions, conversations overheard through normal use of a hearing aid or similar device, and conversations where a party has consented to the recording in writing. The surreptitious-manner element at 720 ILCS 5/14-1(g) is a threshold requirement: if recording is done openly, the offense does not apply even if consent was not given. The police-recording carve-out at 720 ILCS 5/14-2(e) expressly permits any individual who is not a law enforcement officer to record an on-duty officer performing duties in a public place or where the officer has no reasonable expectation of privacy, subject to an officer's reasonable safety and investigation-integrity actions.

Imagine an employee wears smartglasses that silently record video of the sales floor but do not capture audio. The video is fine under Illinois law because the eavesdropping statute is audio-centric. If the glasses start recording audio during a customer complaint, the employee must stop the audio recording or get the customer’s consent first. If the customer objects, the employee should turn off the audio or stop recording entirely. If the glasses secretly record audio without consent, the employee and the business could face felony charges under 720 ILCS 5/14-2 and a civil lawsuit under 720 ILCS 5/14-6. Separately, if the glasses capture a voiceprint of an employee or customer without written notice, consent, and a published retention schedule, the business could face a BIPA claim with statutory damages and attorneys’ fees. Illinois law also requires that destruction of biometric data occur within three years of the individual's last interaction or when the initial purpose is satisfied, whichever occurs first.

The Illinois Supreme Court’s 2014 decisions in People v. Clark and People v. Melongo struck down the prior gateless version of the eavesdropping statute as unconstitutionally overbroad, leading to the current hybrid subjective-intent plus objective-reasonableness test codified in 720 ILCS 5/14-1(d) and 5/14-1(e). The Court’s examples of what the old law wrongly swept in included a loud argument on the street, a political debate in a park, and the public interactions of police officers with citizens. The legislature restored the reasonable-expectation-of-privacy gate via P.A. 98-1142 (eff. 12/30/14). The federal Seventh Circuit’s decision in ACLU of Illinois v. Alvarez, 679 F.3d 583 (7th Cir. 2012), separately held the First Amendment protects openly recording on-duty police in public, a precedent that operates alongside the statutory carve-out at 720 ILCS 5/14-2(e). The enhanced penalty for recording certain officials under 720 ILCS 5/14-4(b) targets surreptitious recording of genuinely private communications involving law enforcement officers, State’s Attorneys, or judges performing official duties, not open recording of public police-citizen encounters.
