Any service interruption in the webcam coverage, motion, power interruption,
etc., should lead to disk wipe if power ifs available. An on-board small UPS
should provide a few seconds of power to allow, at a minimum, the corruption
of the partition tables and superblocks.

And a fast phone call from my homebase should occur immediately.

If you want to get wacko about it, use the really *old* aluminum disk packs
with iron oxide magnetic coating and cause a head crash. The head scrapes
the disk, finely spraying the case with finely powdered, fresh,
non-oxide-coated aluminum and rust, and ignites it.

Can you say "thermite"? Can you say "ignites the other disks in the tray"?
Can you say "China syndrome"?

Yes, this used to happen. It was an excellent reason fot the big panic
switches and halon extinquishers....
