A Whole-Farm Camera Network With No SIM Cards: How HaLow Changes the Sums

Put a 4G camera on the lambing shed and it earns its keep. Put six around the holding — pens, grain store, workshop, fuel tank, drive, gate — and you've signed six SIM contracts that never end. At typical UK data-SIM rates that's £360–£720 a year to watch your own buildings, and every camera is hostage to the same patchy rural signal. Wi-Fi HaLow is the way out of those sums. It's Wi-Fi rebuilt on sub-GHz radio — the same frequencies that let LoRa and old radio phones travel — so instead of 30 metres it reaches up to a kilometre, through trees, around barns. One access point on the farmhouse or a grain silo becomes a private camera network for the whole steading. No SIMs. No monthly anything. Last updated: August 2026. The layout that works The access point goes high and central — farmhouse gable, silo, or the big shed. It plugs into your broadband (or one 4G router if the farm has no line — a single SIM serving every camera). Our 0.1W (£114.50), 1W (£200.50) and 2W (£225.50) APs are really a range choice — 2W for the kilometre-class estate. Cameras match the power class. The 5MP AI bullet (from £120) is the perimeter workhorse — its AI alerts on people, not foxes. The 4K zoom camera with 20x optical (from £185) covers the drive and field boundaries. The fire & smoke AI bullet (£125) belongs in the hay store — it watches for the disaster insurance can't undo. Sight lines matter more than distance. HaLow forgives trees and the odd building far better than normal Wi-Fi, but a steel barn dead in the path calls for mounting the AP higher or choosing the 2W class. The honest arithmetic A five-camera HaLow network — 2W AP plus a mix of bullets and a zoom — is roughly £1,000 of hardware, once. The same five cameras on 4G run £300–£600 every year in SIMs on top of the camera cost, and stop working wherever the mast doesn't reach. HaLow pays for its premium inside the first eighteen months and then watches for free — on your own radio network that no coverage map can take away. Where 4G still earns its place: the single camera on the far field gate beyond any network's reach. That's PTZ-on-a-SIM territory, and it slots into the same viewing app alongside the HaLow fleet.
