I am new in this and i have a question about the DinionXF cameras, if that camera has an analog video out, (BNC connector) which is the DSP 15 bits works, I know that the DSP converts analog to digital signals, and if the Dinion's out is analog, It has a digital analog at the output again? Other matter that I want to know is what is the relation between TVL (Television LInes) and the size (600x500 i.e.) or the horizontal lines, I was searching in the internet and find some formulas that relation with Band width of the video, others with only horizontal lines, and I am very confussed. Than you so much. P.D. Excuse my english but I am peruvian.
