Yes i think this would be a very good service, like in 'World 147' in Sheung Wan, they charge $10 for a recording (including the disc). It helps you to improve your match play by looking back at your own performance. It would be great to put such system on table 13 and 14, but i think it cost quite alot to install right? Even by charging more for a recording I think it is acceptable if such system is installed. The most important is the camera must be installed at the black spot end and in the centre, looking down at the table, not at an angle.
