Nice to join you! I am a freshmen in CCTV field, and I am studying hard on camera system. But I can not understand timing signal (VD,HD, SHP,SHD, V1~V4, H1,H2,etc. ) in camera system all the time. Could somebody give me some introduction? And do you, as a system designer, have some advice or some ducument to me on camera system design? Thank you for your help, and nice to communicating with you!
