I have three wildgame cameras that have 2 metal security boxes that keep the bears from wrecking the cameras. The security boxes can be lag screwed into a tree or used with a strap and locked if necessary. I just usually use a small hand tightened bolt with a nut to secure from pesky bears. You may be able to use the metal boxes with other cameras also. I am selling these because the menu uses very fine print which I cannot read in the woods without reading glasses with my old eyes..
$45 for the cameras and boxes.
