An electronic cargo seal is a smart security device used to protect cargo containers, trailers, and high-value shipments by providing digital monitoring and tamper detection capabilities. Unlike traditional mechanical seals, an electronic cargo seal can record opening attempts, unauthorized access, and security events in real time.

Integrated with GPS tracking and wireless communication technologies, electronic cargo seals help logistics companies, customs authorities, and fleet operators improve cargo visibility, strengthen supply chain security, and ensure shipments remain protected throughout transportation.

A GPS e-lock improves container security by combining physical locking protection with real-time location tracking and remote monitoring. It allows operators to know where a container is located, whether it has been opened unexpectedly, and whether any security risks occur during transit.

With features such as GPS positioning, tamper alerts, remote status monitoring, and instant notifications, GPS e-locks help prevent unauthorized access, reduce cargo theft risks, and provide greater control over container movements from origin to destination.

ECTS stands for Electronic Cargo Tracking System. It is commonly used to monitor cargo movement under customs control, especially for transit cargo, bonded transport, and cross-border logistics. GPS electronic seals or smart e-locks can be used to track cargo location, seal status, and abnormal events during transportation.

A GPS smart e-lock combines physical cargo locking with digital tracking. It can report location, lock status, rope cut events, vibration, movement, and unauthorized access alerts to a tracking platform, helping customs agencies and logistics operators improve cargo supervision.

A smart lock can track and report important security and transportation information, including:

• Real-time GPS location of the container or cargo
• Lock status (locked/unlocked)
• Unauthorized opening or tampering events
• Time and location of security incidents
• Transportation routes and movement history
• Device status, such as battery level and communication status

By collecting this data, smart locks provide supply chain visibility and help businesses, logistics providers, and customs teams make faster decisions while improving cargo security.

This solution is suitable for bonded trucks, containers, trailers, high-value cargo, cross-border transport, transit cargo, and temporary import/export operations that require both cargo security and visibility.

Solar-powered GPS e-locks help reduce charging and maintenance needs during long-distance transportation, outdoor parking, border waiting, port operations, and other extended cargo supervision scenarios.
