The camera reads her plate. She's on the family list. Nothing happens - exactly as it should.
Expected, on the right day, through the right gate. Logged, no alert. If the same truck shows up on the 14th at midnight, that's a different story.
Not on any list. The shed bell stays quiet at that hour - instead the lounge light flashes and your phone buzzes until someone acknowledges it. Every event keeps a photo.
The gate and the house talk over a long-range farm radio (LoRa) - a tiny message that carries kilometres on solar power, with no SIM cards and no internet. The radio carries the "who and when". Bells, lights and gate openers hang off the same network, and a small radio in the ute extends coverage as you drive.
