This DVR has now become very important for the investigating agencies because it can help in bringing the real cause behind the accident. Earlier, the black box of the aircraft has also been recovered, which has already been sent for investigation.
What is DVR?
DVR is a digital video recorder, a safety tool that records the video received from the CCTV cameras installed in the aircraft. This device is designed to withstand extremely strict conditions and stored video data safely for a long time.
How does DVR work?
DVR has a hard drive, which saves videos coming from several CCTV cameras present in the aircraft. These cameras are mainly installed near pilot cockpit, passengers’ cabins, doors and emergency exit. DVR saves the analog video signals from these cameras into digital formats.
When an accident occurs in an aircraft, it is tried to find out what was happening in the aircraft before the accident by decoding the footage recorded in DVR. This footage can play an important role in highlighting the possible cause of the accident. After this horrific accident of Air India, the recovery of DVR can give a new twist to the investigation process. As the recorded data is examined in it, the curtain is expected to be lifted due to the real reasons of the accident.
