RE: [OT] Pager for car alarm

["Ward, David" <DAvid.Ward@xxxxxxxxxx>]

kim,

I've toyed with this a bit.

PAYG SIMs generally require topping up every 4 months or so which for low
volume stuff is fine

An alert system that a friend set up for a home nursing company used a
combination of SMS sent to phone with details followed by an immediate
voice
call to the same phone to provide instant notification,  this is the way
that I would go.  It would also allow the listen in function that most
alarm
auto diallers provide.

For cheap old phones see www.retrofone.co.uk (Just found it today!)

I'm resisting the urge to completely re-implement the alarm unit
(horribly cheap & nasty thing from previous owner) on a PIC and doing
cool things with SMS saying which sensor was triggered and other UKHAish
things...  Although it's probably still sensible to use a proper call
for alarm paging, as text messages tend to get laggy at the most
inconvenient moments.

Being able to arm/disarm from the mobile would be good though, as we
often have to park out of weedy-little-keyfob-transmitter range from the
house.  Hmm...
