 note = {The performance of the long time automatic observation of eruption clouds by Kagoshima University Research Group in remote islands in southwest Japan is reported. The interval recordings at Satsuma-Iojima volcano by digital still and video cameras started in July 1998. A remote control and monitoring system was constructed by using a network camera and a server computer, and it was installed at a school building in Nakanoshima, 25 km north-east of Suwanosejima volcano in August 2002. It recorded many large eruptions. The network camera was replaced by a near-infrared (NIR) type in February 2004 so as to obtain clearer images in misty conditions. A web-camera system connected with the internet was also installed in Satsuma-Iojima in February 2003 and changed into a NIR type in December 2003. The advantages of a NIR camera include the detection of faint aerosols (almost undetectable in the ordinary view), and identification of hot anomalies. Based on these methods, long time automatic observation of Mayon volcano in the Philippines in collaboration with PHIVOLCS started in June 2003 at an observatory 11 km away from the summit crater, initially by using digital still and video cameras. Visible and NIR network cameras with a network attached-storage facility were later installed in February 2004, and connected with the internet two months afterwards. Numerous night-time images of hot lava flows during the summer 2006 eruption of Mayon volcano were subsequently obtained by both the NIR camera, and the video camera using night-shot mode.},
