When I had the front drive put in I made sure we had brick walls on one side and at the rear, I then reversed my works van (at the time) tight to both walls, in this way only the drivers door was at risk, once on the drive I lock the steering hard left, fit a good quality steering lock and a bulldog wheel clamp.
The drivers door has a deadlock so I effect to drive the vehicle way any thief has a number of obstacles to negotiate, none of these are unbeatable, but all will take time.
2 plastic windows leave the contents at risk, but any thief will set off security lighting and CCTV cameras are placed to be obvious.
When you walk onto the drive you set off a beep on the house alarm, the security lights come on and the CCTV pops up on my phone, iPad and a screen in the house.
None of these things will stop a truly committed thief if your not home, but we had a series of thefts from vans, motorhomes and caravans in the village a while back, my neighbour had his works tools taken, a guy down the road lost his caravan and that repeated around the village for a few months.
One night 2 men walked up to the front of my driveway at 03:11am the security lights came on, they looked around and left, it wouldn’t be worth the effort for them when there’s easier targets around.
A point worth remembering, the type of people that do this will become violent very quickly if cornered, if you do confront them be careful and always leave them a way out.
