I've been in the security business for 36 years, video systems, long range wireless, intrusion detection, backup communications, you name it, I have done it. Sad that this type of post is surfacing more and more often.
First law of security is to secrue the perimiter, nice to catch them while their still standing in the dirt. Second to that is to have interior traps, motions, interior doors, photo eyes, glass breaks, etc. The most stable motions are the dual technology, microwave, passive infrared, where both technologies have to trip together in order to initate an alarm in other words a rapid change in IR levels combined with a physical moving target through the air column is required.
Locations of motions are "key". A typical system has 2 or 3, positioned away from moving air sources and pets are a consideration too although I have been using "pet immune" detectors that can diferentiate between a human and a pet up to 40 lbs., they have specific mounting heights and specific requirements as far as distances to a possible pet location (jumping on table, etc). Position them where an intruder is most likely to cross.
A hybrid system that uses hard wrie and wire devices is desireable. If your shop is within 200 feet or so, range should not be a problem.
Phone lines are another consideration for monitored systems. If you really want it secure and dont want to spend the money for a 500-1000 cell backup system, rerun the telco line from the street to the attic and wire your phones from there. Then run a trip wire from the alarm panel back down to the old demark (where the wire from the pole came from) and program that silent, so when the cut the lines, a silent signal goes to the station. They think their home free and usually get caught if it's set up right.
As far as cameras, this is definitly an area where you get what you pay for. You want high resolution, low light cameras, 540tvl, .7,.3 lux or lower. Some black and white units claim .03 lux and they do well in moonlight or a little aux lighting. If there outside you need enviromental enclosures. Forget about getting tag numbers unless you have a camera tightened down on a target or trap area where that's the only place they can park. For anything to stand up in court, there can be no doubt that the image the judge is looking at is definitly the person sitting in front of him or the judge will throw it out.
DVR's Digital Video Recorders are the only decent way to go these days. I use industrial units from a few different manufacturers depending on the application, Pelco (casino grade) Avermedia (nice software, fast and user friendly) and a few others depending on what my budget is.
To give you an ides, I just finished a 3 camera (high end cams) and a 4 channel dvr and it ran him 3700, I made about 600 on the deal I'm not looking for big profit, just trying to help the people out. Another system only has 4 cameras (all very high end) and a 16 channer Avermedia DVR and it ran 8400 but it has a controllable camera that you can program to run patterns and it switches over to b&w at night for better imaging. I could go on forever, if youd like to call me for any more advice email me at jrtzrule@yahoo.com.

Today's Featured Article - Gatherin of the Orange - by Rick Nikolich. In July of 1998 I was talking to fellow Allis Chalmers collector Mike Schilling about the annual "Gathering of The Orange" AC show coming up in August of 1999. He got this wild idea that we should get a convoy of AC tractors and drive them from Charlotte, Michigan 105 miles to LaGrange, Indiana.
