|
Data Storage: all collected data can be saved in both final recording medium and backup recording medium, which both should be provided with certain self-protection to prevent any delete or tamper on the recorded data.
|
|||||
|
Self-inspection: when the system starts running, the self-inspection starts up automatically and sends out a status indication showing if the system runs correctly. System will alarm for any abnormality.
|
|||||
|
Replay: replay the data stored in the final recording medium by the replay device. The data stored in the final recording medium and the backup recording medium can be downloaded
