Here is how you would build a system starting with the security camera that you like:
SONY EFFIO-E CCD 650 TVL 80ft IR Outdoor Security Camera
650 TVL 80ft range IR night vision - weatherproof housing with built-in audio and auto white balance
Price: $99.95 View Details
You could then hook this camera up to a DVR like this (note you need to purchase a hard drive option which will increase the price about $120, the base price is without the hard drive):
4 Channel Security DVR For CCTV Camera System Linux OS
Up to 2 TB drive, motion detection, 3G or network access so you can view on your iPhone etc., PTZ control, USB backup, real-time D1 resolution
Price: $99.95 View Details
Since its an audio enabled camera you would want to use AV cable like this:
50ft AWG22 Premade Siamese Video + Power + Audio Cable
pre-built with 5.5mm power plugs, BNC video connections and RCA audio connections for standard CCTV setups
Price: $24.95 View Details
This would provide you with a very good high quality security camera system. It would also allow you to add more cameras at a later date if necessary.
