The CelloTrack Container Lock is an electronic robust solution based on the CelloTrack Power, offering an agile tracking and cargo monitoring for containers with almost instant assembly and removal, eliminating the need to open the container and interfering with logistics operations such as authority inspections, transport, loading and unloading. It provides information on where the goods are at any given point and if there are any bottlenecks along the way. The device accelerometer senses movement and an embedded magnetic sensor detects when the container´s doors are opened or tampered with.
