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. Cameras keep their pictures at the gate; 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.
