Nearby cameras and distinctive frames (here are some pink ones https://www.ecrotek.co.nz/product/honeymaxtm-full-depth-pink...). Brand the frames, brand the box and lock the hell out of everything.

A fair portion of thefts have been performed by staff at companies too, so that’s worth keeping in mind. Also, get on with neighbours. Putting masses of hives up against a propert boundary, specifically to target Manuka that’s grown next door tends to rile people up.

Better still, jam all GPS, GNSS, GPRS and 3G and 4G signals, along with 2.4, 5 Ghz and LoRa bands just to be sure. Specialized car thieves are already doing it, hive thieves probably not yet. Tracking and removing the tracker is more difficult and can be done later.

Can we track all cell phones in the field? It might be easier to track thieves than hives.

Or left those frames in another hive, creating a chaos of crossed accusations.
