The main problem is, people are very good problem solvers. Sure, you can put GPS tracking or Cell tracking in. But I'm betting you can rig easy detectors for cell and gps signal detecting, pretty soon all those pallets get left behind. You can try securing pallets or hives better, but a 18v grinder will take care of most of that in seconds. The best deterrent is getting good pictures and identifying the equipment used in the theft and being able to track the scum down.
