Hundreds of trucks travel between customs offices in ports and bonded warehouses every day. Most containers arrive at their destinations with seals perfectly intact, but occasionally their contents are missing or stolen! Clearly, if an individual container could be tagged and tracked using GPS the whole process would be much more efficient and easier to control, not to mention, more secure.

With the latest GPS technology, highly sensitive internal GPS and GSM antennas, and rugged waterproof locking mechanism, CT-X8 is a proactive electronic lock that can survive harsh operating environments, and help track and protect valuable cargos in transit. CT-X8 can be attached to container doors from outside with tampering cables wired around door handles. Compared with traditional container seals and locks, CT-X8 provides proof of tampering, showing when and where it happened in real time. It also eliminates the need for travel escorts from customs officials for cargos with questionable containers.

It improves the visibility of high value or high risk transit cargo containers, and allows customs or logistics providers to monitor them in real time. Its no-power-switch design makes it impossible for anyone to switch it off accidentally or intentionally. Its superb power management and configurable operating profile makes it possible to keep pinning locations every second or every hour—lasting for 100 hours up to several weeks.

By using CTX-8, customs or logistic operators will benefit from improved visibility of assets, efficient customs process, and faster cargo deliveries. Its simple user interface design reduces false alarms and chances of malfunction.
