Security Systems Placement of DVR (To keep from Being Stolen)

This really bugs me when I hear someone had a break in and their DVR stolen with the footage of the robery along with everything else. I've heard at least 3 case of this happening in the last year. What good is security cameras if this occurs? You would think companies would market a remote DVR recording type of device (They might already have this?)

So, what do you do? Chain it to the wall or closet or hide it in some hidden wall or crawlspace, but run the wires to your monitor/tv? If there are any inventors out there, make a faraday type cage that attaches to the floor with bolts and a padlock.
