Key Features of GPS Electronic Seals for Secure Container Logistics
A GPS electronic seal combines satellite positioning, mobile communication, tamper detection, electronic locking and cloud-based management. It is widely installed on containers, cargo trucks, trailers and high-value shipments.
Unlike a conventional mechanical seal, a GPS e-seal can continuously report its location and immediately send an alert when unauthorized opening or removal is detected.
Main features
- Real-time GPS tracking
The device can support GPS or BeiDou positioning and upload location data through 4G or 2G networks. Users can view real-time positions, historical routes, stops, speed and mileage from a PC or mobile application. - Instant tamper alerts
Cutting the bolt, removing the cable, opening the lock or damaging the enclosure can trigger an immediate alarm. Notifications can be delivered through the platform, mobile application, SMS, email or API. - Remote authorized unlocking
Reusable models can support remote platform unlocking, Bluetooth, RFID, NFC or dynamic passwords. Every locking and unlocking event is recorded for auditing. - Geofence and route monitoring
The platform can issue alerts when a shipment leaves an authorized route, enters a restricted area, remains stationary for too long or is opened outside the approved destination. - 4G connectivity
Depending on the destination country, the device can be configured with 4G Cat.1, LTE-M, NB-IoT or 4G with 2G fallback. Frequency bands, SIM cards, APN settings and roaming policies must be confirmed before deployment. - Long battery life
Intelligent sleep, scheduled reporting and alarm-triggered wake-up modes help balance tracking accuracy and operating time. - Rugged enclosure
Professional devices should be designed for rain, dust, vibration, impact and temperature changes commonly experienced during container transportation. - Historical data and API integration
The platform records routes, seal status, alarm events, battery level and operator information. APIs can connect the solution to TMS, WMS, ERP or customs supervision systems.
