。2. Description of the Related Art Surveillance systems that monitor stores, buildings, and other surveillance areas using multiple television cameras have become widespread. This type of surveillance system includes a system in which multiple television cameras are switched sequentially at predetermined time intervals, an intrusion detector using infrared rays or ultrasonic waves, or an emergency state detector such as a thermal sensor or smoke sensor. are installed in parallel, and when an abnormality (alarm) is detected in the intrusion detector or emergency state detector, a selection device selects a television camera in the area where the alarm occurs and sends the image to the monitoring center. A method is known in which the transmitted video is recorded on a time-lapse VTR.
