Security Camera Laws in Chicago and Illinois: What Business Owners Need to Know

Understanding security camera laws is essential before installing a surveillance system in Chicago. Illinois has some of the strictest eavesdropping and biometric privacy laws in the United States, and violating them can result in significant penalties. Here’s what you need to know.

Important disclaimer: This article provides general guidance based on our understanding of Illinois and Chicago regulations as of 2026. It is not legal advice. Consult with an attorney for specific compliance questions regarding your situation.

Video Recording: Generally Permitted

In Illinois, video-only security cameras (without audio) are generally legal in:

• Commercial properties — offices, retail stores, warehouses, lobbies, hallways
• Building common areas — parking garages, elevators, stairwells, mail rooms
• Exterior areas — building perimeter, parking lots, sidewalks (public view)

Where Cameras Are Prohibited

Cameras are never permitted in locations where people have a reasonable expectation of privacy:

• Restrooms — any type, even single-occupancy
• Locker rooms and changing areas — gyms, pools, fitting rooms
• Private offices — if the occupant has a reasonable expectation of privacy (debated — see employee section below)
• Residential unit interiors — landlords cannot install cameras inside rented units

Illinois law (720 ILCS 5/26-4) specifically criminalizes video recording in restrooms, tanning salons, changing rooms, and hotel rooms.

Audio Recording: Illinois Is a Two-Party Consent State

This is where Illinois law gets strict. Under the Illinois Eavesdropping Act (720 ILCS 5/14-2), recording audio requires the consent of all parties being recorded. This means:

• Security cameras with audio recording enabled require consent from everyone in the recorded area
• In practice, this means most commercial security cameras should have audio recording disabled
• Video intercoms that record audio of conversations at the door may require notification

Practical Implications

When we install security cameras in Chicago buildings, we configure them with audio recording disabled by default. If a client specifically needs audio recording (for transaction verification, for example), we discuss the consent requirements:

• Conspicuous signage notifying that audio and video recording is in progress
• Written consent from employees who work in recorded areas
• Understanding that visitors who are notified by signage may have implied consent (but this is legally gray)

The safest approach: record video only, disable audio. The vast majority of security applications don’t require audio.

Signage Requirements

Illinois does not have a specific statute requiring “you are being recorded” signage for video-only surveillance on private commercial property. However, signage is strongly recommended because:

1. Deterrence — visible signage enhances the deterrent effect of cameras
2. Reduced liability — signage helps establish that there’s no expectation of privacy in the recorded area
3. Employee notification — courts generally require employees to be notified about workplace surveillance
4. Audio recording compliance — if audio is enabled, signage is essentially mandatory

Chicago municipal codes may have additional requirements for specific property types or districts. Check with your local alderman’s office or attorney.

Recommended Signage

At minimum, post signs at:

• Every building entrance
• Employee break rooms (if camera-equipped nearby areas are visible)
• Customer-facing areas (retail, lobbies)

The sign should state: “This property is monitored by video surveillance for security purposes.” If audio is recorded: “Audio and video recording in progress.”

Employee Monitoring Laws

Monitoring employees in Chicago involves additional considerations:

Illinois Employee Monitoring Act

If you monitor employee email, internet usage, or phone conversations, you must provide written notice to employees. While this act specifically covers electronic communications rather than video surveillance, it establishes a pattern: Illinois expects employers to notify employees about monitoring.

Reasonable Expectations

Courts generally allow employer video surveillance in:

• Common work areas (warehouse floor, retail sales area, lobby)
• Areas where the employer has a legitimate security interest
• Areas where employees have been notified of surveillance

Courts have sometimes restricted surveillance in:

• Private offices (if the employee has exclusive use)
• Union meeting areas (potential NLRA issues)
• Areas where the surveillance appears targeted at protected activity

Best practice: Include surveillance notification in your employee handbook, post signage, and avoid placing cameras in locations that feel targeted at specific individuals.

BIPA: Illinois Biometric Information Privacy Act

If your security system uses facial recognition, fingerprint scanning, or other biometric identification, BIPA applies. Illinois BIPA is the most aggressive biometric privacy law in the country.

Requirements:

• Written informed consent before collecting any biometric data
• Published data retention and destruction policy
• No sale or profit from biometric data
• Reasonable security measures to protect biometric data

BIPA violation penalties: $1,000 per negligent violation, $5,000 per intentional or reckless violation — per person, per instance. Class action lawsuits under BIPA have resulted in settlements exceeding $600 million.

Implications for Security Systems

If your access control system uses fingerprint readers or your camera system uses facial recognition (Swiftlane, Verkada, or any AI-based people identification):

1. Get written consent from every person whose biometrics will be collected
2. Publish a biometric data retention policy
3. Ensure the system vendor complies with BIPA requirements
4. Consider whether the security benefit justifies the compliance overhead

For most Chicago commercial properties, we recommend card/fob/mobile credentials over biometrics — they provide comparable security without BIPA exposure.

Footage Retention and Access

How Long to Keep Footage

Illinois doesn’t mandate a specific retention period for most commercial properties. However:

• Insurance requirements — your insurer may require specific retention periods
• Incident response — if an incident occurs and is reported, destroying footage can be considered spoliation of evidence
• City of Chicago — certain license types (liquor licenses, for example) may have specific retention requirements

We recommend 30 days minimum for all cameras, with longer retention for entrance cameras and high-security areas.

Who Can Access Footage

• Law enforcement — can request footage, but generally needs a subpoena or warrant unless you voluntarily provide it
• Employees — may request footage of themselves under certain circumstances
• Tenants/residents — may request footage related to incidents involving them or their property
• Attorneys — during litigation, footage may be discoverable

Establish a written policy for footage access requests before you need one.

Practical Compliance Checklist

Here’s what we implement on every Chicago security camera installation:

1. Audio recording disabled on all cameras (unless client specifically requests with legal counsel approval)
2. No cameras in restrooms, changing areas, or areas with reasonable privacy expectation
3. Signage posted at building entrances and in key areas
4. Employee notification included in project documentation for the client’s HR/handbook
5. Network security — cameras on isolated VLAN with encrypted access
6. Footage retention configured per client policy (minimum 30 days)
7. Access logging — all VMS/NVR login events are recorded
8. BIPA assessment if any biometric features are requested

Questions?

Camera law compliance should be addressed during the system design phase — not after installation. When we design a security system, we discuss placement, audio recording, signage, and retention as part of the planning process.
