Sorry to hear this. I think we have all forgotten the safe door in our lives. It really makes you wonder why this happens when you work so hard for what you have. I would recommend that you have a professional help you with the cameras and other setup. This MUST include two people walking around the property with comms on looking for blind spots. If any pictures are not clear enough to CLEARLY ID a person it is worthless. They also need to be out of the way and not reachable by the bad guys. Be carefull of internal cameras and your own privacy. The recording device should be hidden and on a backup power supply. Not sure what a "complete system" is but all system have weakness. If you want, PM me and we can talk.
