# Freight Surveillance Cold Chain Reefer Monitoring

Freight forwarders, shipping lines, and terminal operators rely on reefer monitoring to maintain continuous oversight of refrigerated containers throughout transit and to generate verifiable cold-chain records. Sensors capture core temperature, relative humidity, GPS position, and often door-open events multiple times per hour, feeding data to a telematics dashboard or control room. Any deviation from agreed parameters—critical for narrow-tolerance cargo such as fresh seafood, meat, or pharmaceuticals—triggers an instant alert, enabling corrective action while the container is still in transit. This is what sets active reefer monitoring apart from passive data loggers, which record conditions but cannot prompt real-time intervention. The resulting temperature logs serve as primary evidence in cargo claims, compliance audits, and regulatory inspections.
