in a robbery, the electronics equipment goes first, that includes PC/NAS and recording NVR/DVR. Stick with cameras with SD cards. In one occasion, a special request from a designer to include a 16-channels nvr inside a custom build wood entertainment center. Using an external 3.5" HDD enclosure with eSATA, allow me to hide the unit below the NVR (a hidden secret pocket with a hole, just to pass the eSATA cable). Normally, the robbers just disconnect the cables to steal the NVR, leaving the hard drive inside the safe secret pocket.
