Cell cams won't/can't transmit the amount of data I need. I need every single picture and every single video collected, in the highest resolution available. I usually collect about 10,000 videos a year totaling a quarter of a terabyte. That's a lot of cell data from an area with almost no cell signal!
At my place a cell cam is useless as tits on a boar hog unless I set it high on top of the ridge. Zero bars on the vast majority of the ground.
