Abstract
A video recording device includes: a camera which captures a video of a visual-field direction of a wearer; a connection part which is communicably connected to an external sensor which detects predetermined environment information; a threshold information storage part which stores a threshold indicating an abnormal state of the environment information; a determination part which outputs an abnormality determination signal by comparing detection information of the external sensor and the threshold; a control part which outputs a predetermined control signal to the camera in response to the abnormality determination signal; and a display part which displays output information from the camera and the external sensor. When the abnormality determination signal is output, the control part outputs a control signal for transferring output information from the camera to a predetermined storage part.
