An anonymous reader writes "I have a cottage at the end of a long dirt road, no electricity nor internet, and recently some (insert expletive here) wads are using the area as a trash dump: countertops, sofas, metal scraps, tvs — all the stuff they don't want to pay to dump at the landfill. I can't block the road because it's a fire access. But I would really like to have a way to catch who is doing this. Are there any a) waterproof, b) self-contained, c) self-powered, and (ideally) d) inexpensive video-recording units out there? Are there any other creative ways to get the guys? I was thinking of something like a device that will cycle, so that the last week of video is recorded. It could take photos or video, and as long as it's small enough that I could camouflage it well, I suspect I'd be able to figure this out soon. And any idea of what my legal rights are to videotape or record?" Hunters have been doing this for years (with film, and now digital) to figure out prey patterns with cameras that are built for concealment; what else would you recommend?
