A video recording apparatus includes an illumination apparatus applying a modulated illumination light, a control apparatus controlling the illumination apparatus, an imaging apparatus imaging the illumination light and an object at the same time to generate video data; and a storage apparatus storing the video data generated by the imaging apparatus. The control apparatus generates encrypted data by using at least a portion of the video data imaged by the imaging apparatus and encryption information generated as information changing in accordance with a date and time and used for encryption and controls the illumination apparatus such that the illumination light is modulated by the generated encrypted data.
