But seriously...
What's your strategy?
Are you going to make your house impregnable? Damned near impossible.
Are you going to do enough to convince the insurance company that you did what was right and proper, so they should cough up?
Or are you going to try to deter burglars from your house?
Option 1 is no go - If I wanted to get into your house (assuming a standard type house) I could do so easily inside 5 minutes with just a ladder, a small crow bar and a knife.
Option 2 is a minimum standard and frankly, you are dicing with danger here. Insurance companies have a habit of being unreasonable at claim time, as well as at premium time!
Option 3 is your best bet. In particular, things like security lights, additional locks on your doors, good garden gates, wheely bins stored round the back of your house not the front, loose bricks etc removed from garden walls... the list goes on. The first objective is to not make your house stand out from the others in your area in terms of kerb appeal to burglars. This means laptops not left in view of windows, toilet window not left on the latch, etc etc.
Second objective is to make it positively more difficult for a burglar to get in uninterrupted. This means lights, alarms, additional locks (where appropriate) and good gates / fences to prevent them getting in off the street. If they have to stand there in the floodlights and spend ages breaking into your front door, in full view of the neighbours, they are going to think twice. But remember, it's about making your neighbours look like a better prospect - if you do your house up like fort knox, it shows you are either paranoid and just asking to be turned over if you leave your guard down, or you have something worth guarding.
In summary, the best thing you can do is call your local crime stoppers line and get the local fuzz to come over and take a look at your security arrangements. They call this crime prevention / community policing and actually the advice is usually very good and very specific to your local area.
