Spoilage & write-offs
An undetected breach turns a full load into a write-off. By the time the depot notices, the truck is already at the customer — and the freight is past the point of no return.
Cold Chain · Temperature-Critical Fleets
Every degree, every
minute, every load.
Multi-zone Bluetooth temperature sensors integrated with Fleet Destiny — for pharmaceutical, food, and fresh-produce fleets that can't afford a thaw.

The Reality
Cold chain is unforgiving.
One temperature excursion can cost hundreds of thousands — in spoiled stock, regulatory fines, or a lost contract.
Compliance & audit risk
FSSC 22000, HACCP, and pharmaceutical cold-chain rules all require documented temperature logs. Manual records are slow, error-prone, and trivially easy to falsify — auditors know this.
No visibility in transit
Once a reefer leaves the depot, most fleets are flying blind. Door openings, compressor glitches, and route deviations go unnoticed until something goes wrong — and by then, the cost is already locked in.

Cameras
Eyes Where Cold Chain Actually Breaks
Most cold-chain incidents happen at the loading dock, behind closed cargo doors, on the side of a truck during a drop, or while reversing into a receiving bay — not on the open road. Four cameras cover the full chain of custody.
Position 1
Front + Driver-Facing
AI dashcam covers the road and the driver's cabin — fatigue alerts, phone use, forward-collision warnings, and footage 30 seconds either side of every harsh event.
- Driver fatigue + distraction
- Forward collision & lane departure
- Route + harsh-event evidence
Position 2
Cargo Bay Interior
Sealed-housing camera inside the reefer with infrared night vision — because once the doors close, the cargo bay is dark. See loading accuracy, stacking discipline, and chain of custody at every drop.
- Loading + stacking verification
- IR night vision (sealed housing)
- Cargo theft + tampering evidence
Position 3
Side + Loading Door
External weatherproof camera covering the delivery side of the truck — proof of delivery on every drop, footage of who opened which door, when, and for how long.
- Proof of delivery footage
- Door open / close events
- Retailer-dispute evidence
Position 4
Rear-Facing Exterior
Mounted on the back of the trailer, looking rearward — covers the reverse-into-dock manoeuvre, the receiving bay approach, and any rear-collision incident the driver couldn't see.
- Reverse-into-dock footage
- Rear-collision evidence
- Night-time reversing visibility
Cross-referenced on the same incident timeline. Camera footage lives on the ACM video platform; temperature readings, GPS position, and door events live on ACM Destiny — but when an incident happens, the timeline lines up so a temperature breach can be matched to the exact moment a door opened or a delivery was made.

Case Study
Representative18-vehicle reefer fleet · Western Cape produce distributor
Zero temperature excursions in 8 months — and audit prep dropped from 2 hours to 10 minutes.
A Western Cape produce distributor supplying fresh fruit and vegetables to a major supermarket chain had recently absorbed a R280,000 loss and a compliance warning from a single missed temperature breach. After deployment, the operation maintained a perfect cold-chain compliance record across 18 reefer vehicles — three temperature zones per truck, monitored continuously, exported to retailer audit format on demand.
18 vehicles monitored across 3 temperature zones each
Audit documentation cut from 2 hours to 10 minutes
Driver door discipline improved after open-door alerts introduced
