Mark, Not quite as far fetched as you think. With a digital system (Phillips) we can go back several days and yes we can zoom in. Unfortunatly the resolution is not very good. We do have certain cameras that can read the date on a quater on real time. The technology increase in just the last 4 years is almost scary(so are the prices). At this time there are probably less than 50 casinos that are 100% digital in the surveillance room, but this is changing rapidly. I have worked both and I'm not sure the cost is justified. Jim
