A1: These are all abbreviations for the technical standards set forth for manufacturers of video products. CCIR and PAL are the black & white and color formats for much of Europe as well as Israel, while EIA and NTSC are their American, Canadian, and Japanese equivalent standards. The key difference between them is the speed at which the video is ‘phased’- and that PAL cameras are not compatible with NTSC monitors, or vice-versa (unless they feature a dual or multi-format ability). The only thing you really have to know is which format your country uses.
