Great question, having just purchased for Fysh a 2021 MUX, which is parked during working hours in a carparking area hidden from the street.
At home I can't see a problem, it is in a locked garage when not being used.
We do have security cameras, which notify us of when someone enters the house yard, which is great for when receiving deliveries.
Then I have my 80 series, parked under cover, ready to go camping at the drop of a hat, and my 1999 Rodeo work ute with 25 odd K worth of tools, in it.
And I have a trailer with a Zero Turn mower, and associated lawn care tools, soon I'll also have a 10k RC Mower/Slasher.
Do I get GPS Trackers,
A good mate, 18 months ago, bought is wife a 4wd Quad Bike, two days after delivery(in a locked shed, rural), the shedhad the padlock cut, the fence cut, never to be seen again, had got to insure it, ;(
Cops came and finger printed a couple of things, he has heard back, and when he rings about it, "Nothing as yet"
Sorry for the long winded post, I can understand wanting to protect your property, living in a rural area, we hear of theft of machinery, Ute's, trailers, bikes regularly.
I don't know what the answer is.
You don't use magic to disappear, ya use a 4x4 & Swag.
