摘要： The present invention strengthens the security level of an infrared security system. The infrared security system for managing unlocking of a lock includes: at least one detection unit that includes an optical laminate and an infrared detection device which is disposed so as to receive infrared light via the optical laminate; and a security system that operates on the basis of output from the infrared detection device. The security system is configured to generate time-series data that indicates motion of a subject on the basis of a subject signal generated when the infrared detection device receives, via the optical laminate, infrared light which has been emitted from a light-emitting device toward the subject and which has been reflected by the subject, and to unlock the lock on the basis of the time-series data.
