A system for monitoring a container includes a seal, a monitoring device and a communication center. The seal is used to lock the doors of the container. The doors can be opened only when the seal is broken or cut illegally. The monitoring device is connected to the seal when the doors are locked by the seal. The monitoring device is disconnected from the seal when the doors are released from the seal. The monitoring device detects the status and position of the seal when the doors are locked by the seal, and sends related data to the communication center so that the communication center can always determine the position of the container and whether the doors have been opened.
