RG6U aluminum braid cable is not very good for CCTV. Very short runs, under 100' maybe. Aluminum shield is not suitable for the frequencies that CCTV operates at. You should use 75% or better copper braid in CCTV.

I used to sell these when I had a distributing company and they are excellent quality although not inexpensive. Pricing depends on whether you are a dealer or end user. You can get a list of suppliers from the manufacturer. They will work with DVRs also which is nice in case you decide to upgrade in the future.

Try this link. It is one of the better DVR card suppliers that I have found with some pretty good pricing. I have no association with them fyi. http://www.bezerkmedia.com/shop/customer/home.php?cat=291

The frame rate depends a lot on what the cameras are covering. Is it a retail store, a home, or what? Remember that higher frame rates take up much more disk storage and you will spend a lot of extra money on hard drive space if you go with a higher frame rate even though it may not even be needed. In many instances 2 fps is more than enough for surveillance.

This is a camera from Extreme CCTV. It is good below freezing temp. http://www.extremecctv.com/products/uploads/PDF2/EX10_v12.pdf

Check out Transaction Verification Systems. They have the most complete line of register interfaces. Here is a link to try. http://www.tvs-inc.com/cs/2100.pdf

How many cameras do you have or will be using in the future? Also what is being recorded. High value items usually require a DVR with more FPS. Both embedded and PC base systems have their advantages so a lot will depend on the details of your application.

If you just want to replace the VCR with a DVR you can do it easily with a single channel DVR. It slots right in and works great. Very low cost. Try this link for some technical information on a single channel DVR. http://www.vitekcctv.com/ProductDetails.asp?ProductID=162
