The Risk

Numbers restaurants don't want to learn firsthand

$5,200

Average food loss per incident

When a walk-in fails overnight, the average restaurant loses over $5,000 in product — rarely fully covered by insurance.

68%

Failures discovered at open

Most equipment failures happen outside business hours. Without monitoring, you don't know until staff arrive the next morning.

$0

Upfront cost with CAS

We own and install all hardware. Your only cost is the flat monthly fee — starting at $100, less than your daily food waste.

Sensors for Food Service

Every area of your kitchen, covered

We place the right sensor in the right spot. Our standard restaurant package covers your most critical assets from day one.

Walk-In Cooler

Continuous monitoring with alerts when temp rises above your safe range.

Walk-In Freezer

Deep freeze monitoring with instant alerts on temperature rise or power anomaly.

Cooler Door Sensor

Alert when a cooler door is left open beyond a defined time threshold.

Prep Area / Display Case

Add-on sensor for line coolers, display cases, or secondary cold zones.

Water & Leak Detection

Catch leaks under equipment and floor drains before damage sets in.

Power / Voltage Monitor

Know instantly when a cooler, freezer, or critical appliance loses power.

Compliance

Missouri health code — automated

Missouri food service regulations require documented temperature logs. CAS handles this automatically — no clipboards, no gaps, no risk.

What inspectors want to see — and what CAS delivers

Health inspections require evidence that refrigerated storage has maintained safe temperatures over time. With CAS, every reading is logged and timestamped in the cloud. Pull up a full temperature history for any time period in seconds.
