Dirty nappy bucket by the front door, gets more effective as time goes by.

Do you live in a coal mine?

Don't really have one, so would be awesome if I'm lucky enough to win. Good luck to everyone else though.

Currently my sister who pretty much never leaves the house and seems to show up at the slightest sign of anyone's existence downstairs.

Also there is the large flatmate that walks around in his underwear making grunting noises, that should be enough to scare off anyone that makes it in.

Sadly our alarm passed on about 4 years ago...have been without ever since.

Have an old box screwed to the eaves that was here when we bought, but it's not connected to anything

something that actually worked would be nice

Mobile sensors 1 + 2 - #2 only works part time when his owners need a sitter.

Then theres these funny things known as "locks" in the industry I believe. 

Also a box thing on the wall with a keypad which makes a lot of noise when Ive been out drinking and come home late.....

I currently only have a couple of cameras setup watch for things.

Oh and this guy

You can tell he is hard at work in the picture

We live in what some would class as a 'dodgy neighbourhood'. The type where there's always an unregistered dog roaming (currently a tan staffi from 2 houses down). Our home security currently includes 6ft fences and 3 sets of gates (2 internal, 1 set external). Deadbolts on the doors and a doorbell that takes a photo when you press it. Otherwise nothing electronic or gadgety. There also BK our Border Collie who is afraid of my dad but would lick any burglar to death. A decent (/gadgety) security system would be great as I work shift work and my wife is often home alone at night. We got broken into while my wife was home alone a few years ago which really knocked her back.

An alarm is something I've wanted for a long time. I've only got old locks at my house, like this one which I cleaned out fairly recently - manufactured sometime between 1830-1837!!

No system at all, except for locks :)

@t0ny is that any good? I've been looking at them but havent taken the plunge.

I have motion sensors, and an alarm (that also goes off when the shower makes too much steam).

 Current system is ESP alarm system that has a mind of its own and self arms itself.
