While not intended as an alarm system, the Pinnacle ID/TRH might be
able to serve your purpose.  The ID/TRH is actually an internet
datalogger for temperature and RH (hence the acronym) that transmits
its data over the web. It has two additional ports for attaching
compatible motion sensors, water sensors or a webcam.  The unit must
be near an AC outlet and an ethernet connection but maybe this would
solve your problem as you would not have to hide it directly in or
around the display case.  The environmental data as well as alarm
conditions from any of the attached sensors can be viewed real time
on the web site (i.e. at a guard station or front desk, etc). If your
room has these capabilities it may be worth looking at.  The
Pinnacle requires some setup to get it on your network but after
that is very easy to use.  More information is available at
