You can always install it INSIDE the van.  It will fail to annoy the
neighborhood but it will deter whomever decides at close range to violate
the protected space.  Once inside it will be virtually impossible to
concentrate on molestation of the contents unless of course the assailant is
deaf.  In that case no amount of +130db noise will dissuade the thief from
the rapid execution of his appointed rounds.  And no wires will be
available to cut outside to disable the noise.  When entry is made, the
percieved noise level will noticeably increase, a progress report so to
speak to the knowledgeable that the door is open.

The ultimate electro-nag.

If the alarm system includes a starter disabling feature you should very
carefully note on your bently current track diagram just how this feature
affects the starting circuitry.  My venerable alarm system had a relay that
slowly failed.  Took some serious chicanery to figure out that A. it was the
alarm system and B. it was the mystical elusive relay gremlin and C.  Just
where the relay was physically located and D.  What the proper replacement
part was.

Or you could hide a king cobra in a decorative pot inside and claim the
deceased thief tried to steal your pet.

Pensionerd.
