I've been doing trail cams for 2 years now and finally, just last month, had one stolen. I've been keeping a minimum of four in the woods continuously for about 1 year now. Before that I was a little more sporadic, and it was more of a summertime thing. I have yet to secure a camera in any way. I just try to put them in locations that don't get a lot of human traffic. But I also don't have any high dollar cams. The one that got stolen was a Tasco that I got for $40, so it didn't hurt too bad. And I got a full year of continuous use out of it, so I figure I got my money's worth. Some cameras only last a year before they quit working.
