I had one on the first Trophy trail cams, but its batteries never lasted more than a few days. It was great when I hooked it up to my old lamp battery. I used in remote areas of the the farm to keep a eye on who was around. I got some good footage of the wildlife more than anything else.
I have even put it in one of the sheds when a client was helping them selves to the stock. It was great to be able to quote to them time and date and even what they were wearing and what they had taken!
I put one over the drive way when I am away, always good to know who it about. I mount mine with a builders strop and screws at at about 12-14 foot up stood on the top of the Landrover. people don't seem to look up. I was pretty sceptical how useful it was going to be, but now wonder what i would do with out my trail cams.
