Every drawer-open clipped
The POS sends a webhook on each transaction. The NVR auto-tags the camera clip with the transaction ID, total, employee, void code (if any). Search "show me every void over $50 last week" and get the camera clips, not just the receipt log.
Sweetheart-deal detection
The AI vision layer flags suspicious patterns: same customer at the same employee 5+ times in a week, drawer-open with no transaction code, void-then-refund within 60 seconds. Plain-English daily digest.
Drive-thru plate read
For QSR with drive-thrus, the LPR camera reads plates entering the lane. Allow-list common customers (no alerts) / watch-list known dispute cases / block-list documented harassment / theft.
Walk-in cooler alerts
Temperature contact in the walk-in. Phone alert if it crosses 40°F (or your operator-set threshold). Common cause of $1,000+ losses; $35 of sensor.
Closing-checklist CV check
The AI verifies the closing checklist: lights off, register drawer open + empty (cash drop completed), back door locked. Sends a closer's selfie + checklist confirmation to the operator.
Cameras on isolated VLAN
Cameras can NEVER reach the POS network. Cameras can NEVER reach the guest Wi-Fi. The POS network can NEVER reach the cameras. Three-way isolation, documented in the audit pack.
