1. A video recording apparatus with a pre-event circulation recording function, the video recording apparatus comprising:

  • a video receiver configured to receive a video captured in real time by at least one camera;

    a nonvolatile storage unit configured to store the received video; and

    a recording controller configured to control a pre-event video generated before an event occurs to be circulation recorded on a pre-event storage region of the nonvolatile storage unit while complying with a pre-event storage period, and control a post-event video generated after the event occurs to be recorded on a post-event storage region allocated separately from the pre-event storage region,wherein, when the pre-event storage period is temporarily not complied with due to the circulation recording of the pre-event video, the recording controller allocates a spare storage region after the pre-event storage region for complying with the pre-event storage period, andwherein, when returning to a start of the pre-event storage region after recording the pre-event video which has a length satisfying the pre-event storage period, the recording controller records the pre-event video on the spare storage region prior to returning to the start of the pre-event storage region in order to comply with the pre-event storage period irrespective of initial data of the pre-event storage region being overwritten when returning to the start of the pre-event storage region.
