One key to remember is to insure you have multiple paths to the alarm monitor (or ADT etc.) and battery backup for all the devices. It is very easy to cut phone lines or power. If your defense/alarm system is dependant on these and they are cut, you are toast. I would also recommend a secondary system based on monitoring the cars themselves via motion detectors which uses a totally separate path. I had/have a multi channel RF system that ties into the monitor service as well as dials/pages me. Video is good if someone is watching or to identify the culprit after the fact, but by that time you can already be hosed.
