Guys
Can I offer a little advice - I own a Security Company in South Africa where we have high levels of crime (50 murders a day, 200 rapes a day - I could go on) and believe me if you think the Police in the US are either useless or overwhelmed, you ought to see the SA Police - in many instances its THEM doing the breaking in!!
On a previous post I mentioned what I have on my house. I have that as I can and its free to me, sort of thing.
But in most instances if someone REALLY wants to break into your place, not much will stop them.
HOWEVER an enormously high percentage of break-ins in particular, are opportunist crimes.
SO Visible deterrents (which are there to be seen) work best.
Window bars - can be the latest see through unbreakable plastic type work really well - as do door security trelli slam shut door gates - also on patio doors. These are pretty cheap and highly effective.
Dummy cameras work really well and sometimes, particularly if your Police Force is not up to much, work as good as standard static CCTV - well unless you want and sit and watch the monitors all day - even if you get good pictures of the criminals, the police normally say that its no good for a prosecution (way too much work and anyway might be their cousin or something here in SA!!)
And of course a standard pretty simple alarm with a VERY loud horn / bell etc - that normally stops any burglars staying too long.
Dogs with loud barks work great.
We also do cameras that detect movement etc night and day and send pictures straight to your mobile phone, no matter wherever you are in the World - these are the ones we pioneered to help stop Rhino Poaching and they work brilliantly.
One of the best deterrents is of course instant response - here in Cape Town we have guaranteed 2 minute armed response - not sure if available in US - I know the armed bit is not available in the UK. They MUST be armed in Cape Town or they would soon probably be dead, but TIA as we say (This is Africa!!)
Also simple things like decent perimeter wall / fence - a gate if you can - all these things the potential burglar will see, think twice and then look round for a softer target...unfortunately in many instances its your neighbor, but well, they should have boosted their security as well. It sometimes is a good thing to just remind them they might be a little vulnerable and they should look at their own security situation.
Neighbors who all think a little about security and all have some kind of visible deterrent, REALLY are safer - the actual area where I live, we all (bar the odd house) have improved our security over the years and because of that, so far, we have a very very low incident of crime - stronger together sort of thing.
Hope some of this is helpful
Cheers
