The optical system includes a lens. The irradiator irradiates a wave, different from a visible light ray, in a night mode. The illuminance sensor is installed in a light receiving direction different from a light receiving direction of the optical system. The photoelectric converter is configured to convert light from the optical system into an electrical analog image signal. The analog-digital converter is configured to convert the analog image signal from the photoelectric converter into a digital image signal. The main controller is configured to control the surveillance camera to switch between a day mode and the night mode according to gradation of the digital image signal and illuminance sensed by the illuminance sensor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Surveillance camera","description":"Provided is a surveillance camera including an optical system, an irradiator; an illuminance sensor, a photoelectric converter, an analog-digital converter, and a main controller.
