There are a number of companies making fiber optic cable systems which will do
the job.  LightGard is one example though you can probably find a less
expensive competing brand elsewhere.  Here's a URL:
http://wcsc.stores.yahoo.net/ligpreasdet.html.  Fiber optic systems are
extremely difficult to compromise without special hardware and knowledge.  The
down side is the cost.

A less expensive option uses coaxial cable.  This one you could probably DIY
though there are packaged solutions around which work in similar fashion.  The
coax needs to be looped through a permanent part of the protected object to be
most effective.  A simple, 24-hour, EOL supervised alarm circuit flows through
the coax.  Cutting or shorting the coax will trip the alarm.  Rig the loop
from the panel to a tampered j-box near the cameras.  Mount two RCA, F or BNC
jacks to the box.  One is other wired to the alarm circuit from the panel.
The other has an EOLR wired across it.  Plug the cable into one jack, loop it
through the protected object and plug the other end into the other jack.

Remember to tamper the J-Box cover.
