Callum,There will be a paper on this in the JBAA soon but here is a short summary.The video system consists of a Watec 902H2 Ultimate camera with a 3.8mm, f/0.8 lens in a waterproof, heated CCTV housing. The camera has a field of view of 96×72 deg and is aimed at a point around 45 deg elevation in the SE. Composite video from the camera is digitised by a Hauppage PVR250 hardware MPEG2 encoder card and stored on disk at a rate of around 3GB/hr. The video is analyzed in non real-time by a separate software process which looks for candidate meteor events. This software extracts segments of video around the times of the candidate events for further investigation. The video is standard CCIR TV format, i.e. 720×576 pixels, interlaced, at 50 fields (25 frames) per second.Nick.
