No. Needs to be all-analog. Analog to digital conversion adds an irreversible pixelation. At least with an all-analog system, if you see someone you want to get a better look at, you can go back to your analog source and digitally zoom in and sharpen it at whatever resolution you find appropriate instead of whatever the camera system happens to be. With a digital system, you can't do that at all. See someone you want to get a better look at? Well, too bad, your digital camera has already given them that wonderful, pixelated-suspect-on-COPS look. > Also, what kind of minute detail are you talking about?
