I went to a hunting expo in Memphis a couple of weeks ago. There was a booth selling trail cameras. The camara (I think it was a Vivitar?) was in a Pelican 1150 case, and the sensor was in a nifty case with the switches for on/off, time delay, etc. mounted in a prepackaged unit which was attached to the inside of the lid. I asked the guy if they built the sensors or what and he told me they bought them already assembled, switches and all from a company in Alabama. The name of the company was something "outdoors" or "adventure"....I think. Has any body seen or heard of them before. If you could buy the sensor unit like he said, it would just be a matter of connecting it to the camara and you'd be done! Has anybody else seen this? Sorry, but I can't remember the brandname of the trail camara.
