Anyone have any input on the best way that a small business could set up some security camera's. I'd prefer wireless cameras as then I wouldn't have to run any network cables. What's needed in the way of a computer processor speed and harddrive size? How to secure the cameras? If I had an aging notebook with a 233 processor and 4 gig harddrive, could I hook up an external harddrive to it and let it store the video? Could I set up a good system of maybe 5 to 10 cameras for under a thousand if I don't have to buy a new computer to store the information? Is a specialty software needed to handle all this?
