That's it.
I'm gonna put together a camera system with miniature pinhole passive; electrically, thermally, audibly, odor insulated detectors packaged in a natural available material such as a log or rock so that it cannot be detected.
It will be so undetectable that we will have to record the gps coordinates in order to retrieve it weeks later. I'm talking, blend in with the environment like any other rock/log. I think the technology is finally getting to the price point of allowing us to do this.
