Burglar alarms aren’t the be-all and end-all of security. There are plenty of different things you can install in your home that will help to stop a burglar from gaining entry — and many of them are very simple and affordable.
The key is to secure the probable points of entrance. This usually means that doors should be made of strong, solid substance (definitely not plastic or glass), be properly fastened to their hinges and also have tamper-resistant locks. Ideally, you need to have an extra deadbolt that you put on at night, made from very strong metal.
Windows should be made from toughened glass, preferably double-glazed, so that they’re almost impossible to break. Although window locks are rather rare, they help greatly with safety, and you should look at installing them. If your home has windows at a situation where they can be easily and discreetly accessed from the road, such as basement windows, you need to consider putting metal bars on them.
It’s also important for the own garden to be secure, as far more thieves enter through the back of your house than the front. This means that your fences must be high and also have some kind of anti-climbing measures (spikes or anti-climb paint will work nicely). If you don’t like fences, get huge hedges instead.
Another thing to consider is getting a puppy — astonishingly effective against burglars, who do not generally want to mess with puppies if they can avoid it. For this strategy to be successful, put a ‘beware of the dog’ sign. Smaller dogs are not so ideal for this since they aren’t generally frightening — something like a big German Shepherd functions best, not only because of their size but because of the strong guard instincts that cause them to be aggressive to strangers.
