1.
You have at least one good reliable guard dog kept running loose on the property.
This means that all visitors need to be accompanied from the gate for their own safety. THAT is a good enough dog.
2. The house is occupied at all times.
We had at least one 'helper' who was always a trustworthy close relation of the ex. Strict instructions NEVER to open the gate let alone the front door.
3. Keep a low profile in your neighbourhood. Allow as few locals as possible into your house (tradesmen etc). Deal with them in a businesslike manner and watch them like a hawk. Avoid antagonising any of the locals and never display signs of wealth openly.
4. CCTV is fine, but an unnecessary expense and distraction IMO.
I just made my own dummy system complete with little flashing LEDs.
My most visible camera was actually made from the body of an old car footpump and some bits and pieces of aquarium equipment. Looked the business and cost about tuppence. lol.
5. Make it harder and more time-consuming for people to get into the house once they're over the walls.
I lined front and back doors with sheet steel...screwed on, and for night-time had steel bars that dropped across the inside of the doors top and bottom into specially fabricated brackets which were attached using long bolts right through the wall. I put locking bolts into the frame on the hinge side of the doors too. All simple DIY stuff.
Test everything yourself. If you can get in ANYWHERE using a crowbar, then so can a robber.
Local locks and padlocks are usually rubbish so take some decent ones from UK.
I thought Brixton was supposed to be up and coming............
