My brother works for an company that restores nature. He has a problem with some people at a jobsite that keep plugging up a drain. One time they put a huge log in front of the drain then some sandbags and now they people concreted the hole shut. He was thinking about getting a cuddeback no glow. Has anyone every used one of these cameras? The other problem the only tree closest to the drain is 150 feet away. Anyone have any ideas to set the camera up so they couldn't take it if left in he open. Thanks
