Some great advice going on here.
Here’s my opinion, not that is worth much.
Snap safe locks: brilliant and really do work. They are so easy to fit yourself, please don’t get someone else to do it and pay a fortune. Simply take out the lock barrel in your door, normally removed by removing one screw after taking the handle off and measure it. Loads of YT vids on how it do this. If not sure, do the above when someone else is in the house and just take the barrel to your local hardware store and ask for snap safe barrels. Usually around £50-£60 for decent ones. My next point is about these locks. There are brilliant but if sh!tbags want to get in, they will get in at all costs! These locks are useful to hold them up a little or make them make more noise if they can’t get through the door but they aren’t full proof. There has been a technique where they blow torch around the locks as most doors are upvc so the heat shrinks it and therefore they have more access to the lock to remove it and in they go.
Door jammers again are useful but aren’t full proof. Again they cost them time and noise to bypass them.
If they think you aren’t in they will make as much noise as they want.
House alarm: I would always say have one. Yes they don’t stop them coming in but a loud alarm going off not all panics them but also alerts other people. This can put them on the back foot as they don’t want to get caught so will do what they have to do quickly and won’t hang about. If they don’t get what they want quickly, they will leave fearing someone coming in or Police turning up.
Security lights: Again worth it for that little bit of distraction and wondering who might see them.
CCTV: as already mentioned doesn’t put them off as normally masked up but believe me, these sh!ts wear the same sh!te clothing all the time and ID is often possible even when masked up.
Lights on timers: if you are going away, use the smart plugs for your lights on a night and early morning. Again can make the difference between your house getting done over if they have been watching. The lights being on and off will make them things someone is actually in. Also there is a really handy little gadget that is an LED light that emits lighting like a TV. Have this on a timer in the living room and makes it look like someone is watching TV. Only issue with that is curtains and I know we all stress about what to do with them when we go on holiday. Personally I leave them open but some windows we have blinds so angle them down slightly so not as easy to look I .
For me combine all the above and it puts you in a better position to protect your property from these absolute pieces of dirt!
You can really go mad on all this, crook locks, disc locks, security posts, all again are a deterrent but most things can be bypassed, the more there is though, the more likely they are to give up trying.
I’m certainly not a fount of all knowledge on this but pick up a few bits along the way so hope it helps a little.
Like I said at the beginning, really good post this for us all to give out experiences and what we think works for us.
