edit:
the previous responses kind of surprise me. its not too difficult to get a DVR with great quality and 21 days stored tape at 20fps. and if you have wads of cash, you can get that for 2 months at 30fps. by good quality, i mean a higher res than 800X600 and not out of focus/ blurry. this is not hard to do.

1) Quality remote controlled video cameras
2) Coaxial cable/fiber transceivers (can be done with ethernet if you like)
3) 128 input DVR bank to record everything
4) Monitor and control board
Done.

dumbass, the resolution is low is because they have to store tons and tons of video, in many cases several days or weeks. if they stored HD video then they would have to have massive storage arrays to hold it all.

Definitely need some higher quality cameras. I have a surveillance system for my house and would like to buy better cameras for it, but high resolution CCTV cameras are hard to find. The ones I have are something like 420x300 (don't remember exactly). Which means you need a pretty close picture for a face to be recognizable.
Storage isn't really a problem for digital video systems. I can store about a weeks worth of cruddy video from my 2 cameras with only an 80 GB hard drive. That's with cameras running about 22 hours a day, 7 days a week. With 500 GB hard drives being affordable these days, storage is not an issue, even if you use high resolution cameras.
Anyone know where to get some high resolution CCTV cameras with changable or vari-focal lenses?

At some of the bigger stores, surveillance is top notch. At one of the big box home improvement stores, the cameras have the capability of zooming in to read the serial number on a dollar bill a cashier is handling. People involved in loss prevention can do just that when they review the footage stored if they're so inclined.

No idea. You could try to find something on Panasonic's and Sony's site. I believe they rule this arena.

But these cameras are not HD capable. They are just high quality cameras with a good zoom.

As others said cost. The VAST majority of time recorded is of no interest it's the one robbery out of 300 days worth of tape that they are recording for. That's a LOT to store. FAR too much for your average convenience store selling penny candy and gas.
Having said this more stores are moving to digital systems, I know since I work in 7-11, but even they aren't any where near HD.
