You can make a reliable alarm with just a few relays, a reliable
chargeable power supply, a secure keyswitch or keypad to turn it on
and off, and some simple magnetic or PIR sensors, and a digital dialer
and/or sounding device.  You can even purchase pre-made time-delay
circuit boards for entry/exit functions. The basic alarm components
have not changed all that much in years.

The computer/microprocessor part is going to mainly add convenience,
multiple zones, status indicators, possible remote control, and a
whole bunch of other features.  It does not necessarily make the
overall alarm more reliable, but it does generally make life easier
for the installers.  It also gives the homeowner a bunch of added
value features that he is probably paying a premium for.  It also
complicates your life when you want to change your monitoring company
and need to re-program your system.

Nobody who cares about reliability would want to tie the sensors
directly to a Windows comptuter.   For one thing, if your are like
most computer owners, others have control of your computer when it
comes to updates, NOT YOU!  We've all experienced the crashes, the
untimely reboots, the "System needs to shut down - Do you want to
notify Microsoft?" messages.   Do you want your mission critical alarm
software co-existing in that environment?
