I hope you don't mind me jumping in on this post but I am looking for more or less the same thing. I have been asked to install 2 cameras for 2 dartboards. The idea is to use a 4 channel cctv system with 2 channels for the boards and the other 2 to show scoreboards (screen split into 4). The cameras will be installed about 2m from the boards slightly to the side and the boards are about 45cm diameter. The scores will be fed from PC's so I will split and convert to HD or composite for the DVR. Basically I need help on what camera/focal length I need preferably with HD quality as these will be fed into large screen tv's around the bar. Whether they are the standard coax or poe etc depends on the cost as I need to buy the complete system. I am based in Crete, Greece so I would need to source everything here. Any help or pointers would be much appreciated.
