A DIY alarm won't be remotely monitored by a professional company and
those are the only alarms that really act as a deterrent.

Class A alarms, usually found in commercial premises, are the only
ones properly monitored and which will produce a police response.

Most domestic "monitored" alarms are Class B Auto diallers such as
used by ADT on their cheaper offerings. Even assuming the incoming
scrote forgets to disable it on entry all it does is phone the
receiving centre who simply phone the contact they have. They don't
alert the police.

As most alarm companies (including even ADT) offer both class A and
Class B installations it isn't possible to tell if a house has a Class
A alarm with police response from the outside.

My point was that it is quite possible to tell if the alarm is NOT one
that could be monitored.

Like hell it is with a DIY alarm system.

I don't know what you do in the outback, but in Britain, if it is not one
of a few professionally installed systems, it won't be centrally
monitored.

Makes a lot more sense to monitor it yourself now
that mobile phones make that so cheap and effortless.

Yes, there are undoubtedly a few who cant monitor their
own alarm, most obviously with those that are out of
mobile phone coverage at times or who have to turn
their phones off at times, but that's a tiny minority.

Even if you do fly a lot, you can get someone else you know
to monitor it for the time you are actually in a plane etc.

The crooks know which those are

Its just not possible for the crooks to know which DIY alarms
are being monitored by the owner of the DIY alarm. Another
good reason to not bother with centrally monitored alarms
unless you have no choice on that. And even with those, its
STILL better to add your own DIY monitoring to a 'professionally'
installed alarm system.

and also know the Police are not going to respond to a report of an alarm
sounding unless they get a call from a recognised central monitoring
station or the caller can actually see somebody in the property.

Another good reason to either have a DIY alarm which
you monitor yourself, or a 'professionally' installed
alarm system which is centrally monitored and which
you have added your own DIY monitoring to.

Not a shred of rocket science whatever required for either approach.

It isnt even that expensive and is MUCH cheaper than any
centrally monitored alarm both on initial and ongoing costs.

I wouldn't do it if I was running a bank, but would for my
house unless I was say a diamond dealer who kept all the
jewels at home etc.
