Bugger Geoff that's a crap way to start the morning. Hope there's not too much damage.
I've recently bought a couple of large halogen sensor lights. I plan to fit an extension lead to each of them and mount them in various positions around the camper. That way if they take one out there are still others to light up the area. I also have fitted an infrared beam across the driveway with a buzzer in our bedroom, this should alert me to anybody entering.
