How to choose a reliable CF Card for your VDR?
VDR (Voyage Data Recorder) is an instrument continuously recording real-time data of ship body, including speech communication signal of cockpit, sensors data, alarm status and radar images , at the time ship breaks down. Before deployment, VDR is tested and approved to be resistant of fire, puncture and deep immersion to make sure the data is well stored and recoverable after accident happens. Based on these data about ship navigation and operation, accident investigation will go smoothly and root cause could possibly been found. Nowadays technical trend of VDR is to expand the data collection range (e.g. including video signal) or extend the recording time (24 hours or longer). To achieve such goals, capacity of the storage has to be larger. Thus in near future storage solution used by VDR should enlarge the capacity to maximum extent while guarantee the reliability as well. However because of the harsh environment of ship navigation and electromagnetic interference release...
