What is DVR
DVR, or digital video recorder, is a security device installed in aircraft. It records footage from the CCTV cameras present on the flight. The DVR utilized in aviation is specifically designed to withstand challenging conditions and can record for extended periods. Following the flight review, data from the DVR can be retrieved.
How DVR works
The DVR functions as a storage device equipped with a hard drive for local data retention. It stores footage from CCTV cameras located in the cockpit, passenger cabin, entry and exit gates, and emergency exits.
The device safely encodes the analog video signals from the CCTV cameras digitally. Most DVR camera recorders utilised in security applications employ signal encoding. The stored footage can be decoded when necessary. In the event of an airplane crash, the recorded footage from the DVR will be analysed to potentially identify the cause of the incident.
