PROBLEM TO BE SOLVED: To realize night viewing to a long distance without making a camera larger by arranging many infrared light emitting diodes movably together with a camera part and arranging the edge parts of many infrared light emitting diodes so as to profile the inner surface of a dome type container. SOLUTION: Three infrared light emitting diodes 34 are attached to a camera part 23. A stay 37 is attached to the lower part of the camera part 23 so as to fix a substrate 35. Many infrared light emitting diodes 36 are dispersed at three steps on the substrate 35 and arranged so that the edge parts may profile the inner surface of the case 33 of the camera part 23. Since many diodes 36 are rotated together with the camera part 23, infrared rays always irradiate the photographing area of the dome type noctovision camera. Since the lower space of the camera part 23 and the camera case 33 is set as the arranged position of the infrared light emitting diode, the diodes are housed without making the case 33 large and infrared rays are effectively used.
