Security Advantage

What type of home security is the most expensive?

I'm writing a story, and I need to know what security system a billionaire would use to protect his home (which houses many expensive artifacts). It doesn't have to be the *best* security system--on the contrary, it would be better for my story if it were less efficient than other, cheaper brands--but I'm really at a loss as to where to find that information. Also, if the most expensive security system available *isn't* the best, please let me know which one is, and the differences between them. :) Thanks!

1. The reason you can't find the information is that highly expensive security systems aren't advertised in the same way regular home security systems are. In real life, what would happen is ADT or Broadview Security would probably have a "high end" package where there are sensors and fences and what have you. Just make up a company with a plausible name.
2. Haven't installed anything for a billionaire yet but some of our clients are in the 100's of millions. An alarm system just like anyone else would have except that we install additional modules that allow for many zones to be monitored via infared, motion detection, glass sensors or magnetic contacts on windows/doors. Most of these people are rarely in the same home so they like to have a CCTV system that can be watched or monitored via the web when they are out of town. Plus the system will have a month or two of running data on a DVR. Lastly would be locks. A couple of these customers went with Vault Doors instead of a traditional door. It looks like a regular door but is basically a safe door with 1.5" metal rods that throw at 10 points of the door. UL rated for both fire and burglary.
