1. The Audio Rule: All-Party Consent

Illinois' eavesdropping act (720 ILCS 5/14) requires consent of all parties to record a private conversation. For dash cams this means: cabin audio recording without passenger consent carries criminal exposure — one of only about a dozen all-party states. Video recording is unaffected. The practical setup for IL rideshare drivers: video-only recording, cabin mic disabled in the app (our firmware has the one-tap toggle), or explicit posted consent signage accepted by riders.

2. Mounting: Standard Obstruction Rules

Illinois follows the general windshield obstruction standard — no object in the critical sightline. Behind-the-mirror mounting is compliant and universal among IL installers. Note Illinois' annual vehicle inspection (for most vehicles, biennial) doesn't test dash cams.

3. Trucking: Illinois Is a Fleet Crossroads

I-80 and I-55 make Illinois a national trucking crossroads, and Chicago's convention-center density makes it a claims hotspot. IL commercial fleets increasingly run multi-camera systems: road-facing, cabin (video-only per the audio rule), and trailer coverage. Our TM-series 12/24V monitor systems and 4G units with CMSV6 platform integration are built for exactly this spec — and IL-based fleets report insurance pricing conversations that start with the camera list.

4. What Illinois Drivers Should Buy

The IL spec: dual-channel exterior with GPS (the A5 class), parking mode via hardwire for Chicago street parking, and supercapacitor power for the Midwest's -20°C winters — our entire line runs supercaps that tolerate deep cold without the lithium swelling problem. Fleet buyers: the 4G P85/M77 lines add remote live view for dispatch.

5. Retailer Note

IL retailers should lead with the audio-law education ('video yes, cabin mic off — here's the toggle') because it positions the store as the compliance expert, and winter is the replacement season: supercap messaging sells the upgrade. Wholesale from MOQ 1 piece, English firmware, 12-month warranty.
