AbstractWe report on the development of the video meteor observation system that runs underthe Linux operating system on x86 processor based personal computers. The system has three highsensitive CCD video cameras. Two of the cameras have a field of view of 31 .2 x 23'.6 with a limitingmagnitude of 5.5, and the rest has a wider field of view of 56'.7 x 43'.4 with a limiting magnitudeof 3.5. NTSC video outputs from the cameras are digitized into either 640 x 480 or 320 x 240 8bitgray scale frames with a rate of 30fps and stored to hard drives. After the observation, the analysissoftware detects the meteors from the captured frames. The detection limit of meteors is about1 .5 magnitude brighter than the limiting magnitude of stars.We observed the 2001 Leonid shower with our system from 15hOOm UT to 2lh00m UT on 2001November 18, and detected about 1100 meteors.
