To provide a video recording device and video recording method that can specify a situation where tailgating driving was performed after the fact.SOLUTION: The video recording device includes: a recording unit that records vehicle neighborhood video generated by a first camera installed at a predetermined position of a vehicle; an event detection unit that detects a first event occurred in the vehicle; a tailgating detection unit that detects tailgating driving that the vehicle suffers as a second event based on the vehicle neighborhood video; a protection period setting unit that, in a case where the event detection unit detects the first event, sets a first protection period based on a detection time of the first event, and in a case where the tailgating detection unit detects the second event, sets a second protection period longer than the first protection period based on a detection time of the second event; and a protection unit that protects video generated in each of the first protection period and the second protection period set by the protection time setting unit in the vehicle neighborhood video.SELECTED DRAWING: Figure 2 【課題】煽り運転が行われた状況を事後的に特定できる映像記録装置及び映像記録方法を提供する。【解決手段】車両の所定の位置に設置された第１のカメラによって生成された車両周辺映像を記録する記録部と、前記車両で発生する第１イベントを検出するイベント検出部と、前記車両周辺映像に基づいて、前記車両が受ける煽り運転を第２イベントとして検出する煽り検出部と、前記イベント検出部が前記第１のイベントを検出した場合、前記第１イベントの検出時刻に基づいて第１保護期間を設定し、前記煽り検出部が前記第２イベントを検出した場合、前記第２イベントの検出時刻に基づいて前記第１保護期間よりも長い第２保護期間を設定する保護期間設定部と、前記車両周辺映像のうち、前記保護時間設定部により設定された第１保護期間及び第２保護期間の各々において生成された映像を保護する保護部と、を備える。【選択図】図２
