Camera-related state law

The governing audio statute is Wis. Stat. 968.31, the Wisconsin Electronic Surveillance Control Law. The Act makes intentional interception of any wire, oral, or electronic communication a felony unless a party to the communication consents. Wisconsin is a one-party consent state for audio recording.

Video-only surveillance of common areas with posted notice is generally lawful. Wis. Stat. 942.08 (invasion of privacy) and Wis. Stat. 942.09 (representations depicting nudity) reach hidden cameras in places where privacy is reasonably expected. Posted notice at the entrance is the industry standard.

Practical translation. Commercial WI camera installs default to video-only on the cameras and route audio capture through a separate documented intercom or call-recording workflow.

Electronic system contractor licensing

Wisconsin DSPS regulates electronic system contractors and electronic system journeymen under Wis. Stat. 101.654 and Wis. Admin. Code SPS 305. Companies installing burglar, fire, or low-voltage electronic systems for compensation must hold the appropriate state credential, and individual journeymen performing covered work must be credentialed.

For commercial buyers, the practical takeaway is that any vendor installing electronic security in Wisconsin should provide a current DSPS credential on the proposal. Buyers can verify the credential at dsps.wi.gov.

Biometric data and breach notification

Wisconsin has not enacted a comprehensive consumer privacy law as of early 2026. Wis. Stat. 134.98 is the primary regulatory anchor for biometric records held by businesses, requiring notice when personal information is acquired by an unauthorized person. Personal information under the statute includes biometric data used for authentication.

For commercial security buyers, the practical reach is fingerprint and facial-recognition access control. Operators document consent at enrollment, retain biometric templates only as long as the operational purpose requires, and apply reasonable safeguards. Wisconsin's adjacency to Illinois (BIPA) means many Wisconsin-headquartered employers with Illinois employees must also comply with BIPA and find it operationally simpler to apply BIPA-style consent forms across the footprint.

Privacy in the workplace

Wisconsin does not have a single workplace electronic-monitoring statute. Pure video surveillance of common work areas with posted notice is the routine pattern. Cameras in employee-only spaces with a reasonable expectation of privacy are off-limits.

Most WI employers issue a single workplace surveillance notice in the employee handbook. Audio capture is regulated by Wis. Stat. 968.31. Manufacturing employers across Milwaukee, Madison, Green Bay, and the Fox Valley commonly add badge-tied access control to production zones.

Video retention requirements

  • Healthcare. HIPAA Security Rule (45 CFR Part 164) governs PHI-touching footage.
  • Retail and hospitality. PCI-DSS Requirement 9 specifies 90-day retention for the cardholder data environment.
  • Federal contractors. NDAA Section 889 controls vendor selection. Retention is contractor-driven through the SSP.
  • Schools. FERPA reach for K-12 districts and higher education.
  • Hemp. DATCP and USDA rules for licensed hemp operators.

Default retention for WI commercial systems with no specific industry rule is 30 days.

What Tec-Tel does to comply with Wisconsin regulations

  • Video-only on cameras unless audio is documented with one-party consent under Wis. Stat. 968.31.
  • Posted surveillance notice at every public entrance.
  • No cameras in restrooms, locker rooms, dressing rooms, or any space where privacy is reasonably expected.
  • Biometric capture documented at enrollment with a written retention and destruction schedule.
  • Retention configured to the regime that governs the industry (HIPAA, PCI, NDAA), with the facility's written retention policy attached.
  • NDAA Section 889-compliant vendor selection on federal-touching installs.
  • DSPS-credentialed contractor work where the install scope triggers SPS 305.
