Weeellllllll, he did have cameras watching cameras, but they found the lot, and some were hidden up stumps! From what the coppers informed him is that whoever it is that is pinching them has an IR detector and it is easy as to find them all.
A year or so prior to them cleaning his cameras out he did catch a couple of blokes on cam checking his place out (old mate doesn't live there full time, he has a Cattle block up in the gulf country) Took to the photos into the local cop shop and showed the girl at the front desk, she just giggled and called out a couple of cops from the back, when they came out they where the same two in the pics!!!!! Turns out they where investigating a report of someone growing dope in the area, they found nothing of course, still has me scratching my head as to why a couple of cops can just walk onto your place to check things out with out a warrant
