In Japanese, ドライブレコーダー (drive recorder) almost always means a dashboard camera that records video. An event data recorder (EDR) records vehicle sensor data and is not the same thing. Use イベントデータレコーダー or EDR for the crash data device.
ドライブレコーダーは映像を記録しますが、EDRは車両のデータを記録します。
A dashcam records video, but an EDR records vehicle data.
Literally 'drive recorder', but this usually refers to a dashboard camera that records video, not the crash data recorder. Use with caution; it may cause confusion.
Often means 'dashcam', not the crash data recorder. Only use if context clearly refers to data recording, not video.
