Lambing & Calving CCTV: A Camera on Every Pen, Without a SIM in Each One

The hardest weeks of the year aren't cold or wet so much as broken — broken sleep, the walk out to the shed at 2am and again at 4am to check a ewe that looked fine last time, the calving you catch just too late because you couldn't be in two sheds at once. Everyone who's lambed or calved a block knows the feeling. The thing that changes it isn't a better torch. It's being able to see every pen from the kitchen, all night, and only pulling your boots on when there's actually something to do. That's a camera on every pen — and the reason most farms have never done it is cost. Not the cameras: the SIM cards. Fix that and the whole picture changes. Last updated: September 2026. Why one camera on the shed isn't enough A single camera pointed down the passage shows you that something is happening but rarely what — which pen, which ewe, whether that's a bag or a leg. By the time you've walked out to look, you've lost the early minutes that matter most in a hard lambing or a backwards calf. What actually saves stock is a view of each pen: the individual ewe you're worried about, the heifer due tonight, the pen of triplets you're topping up. That means several cameras per shed, not one — and often across more than one shed. The real reason farms stop at one camera Put a 4G camera up and it needs its own SIM and its own monthly data plan. That's fine for one. But a camera on every pen across two or three sheds is a dozen cameras — and nobody's signing a dozen never-ending SIM contracts to watch their own buildings. So farms compromise: one camera, one view, and back to the 3am walk for everything else. Wi-Fi HaLow removes the reason to compromise. One gateway plugs into the broadband or 4G router you already have, and every camera links back to it wirelessly — no SIM, no data plan, no monthly cost behind any of them. Adding the twelfth camera costs no more to run than the first. That's the whole trick: when cameras are free to run, you stop rationing them, and you cover every pen. We laid out the sums behind this in how HaLow changes the sums on a whole-farm camera network. A camera on every pen — and the outlying sheds too HaLow isn't short-range Wi-Fi. It runs on sub-GHz radio, so a single gateway reaches cameras up to a kilometre away, through walls and around buildings. The lambing shed by the house, the calving shed across the yard, the far shed down the track — all on the one network, all on your phone. Mount the cameras over the pens, pair them to the gateway, and the whole setup is plug-and-play. The full picture is on our whole-farm CCTV page, and the kit choices are in the Wi-Fi HaLow cameras for farms and estates guide. Watching the night from the house Once it's up, the night looks different. A screen in the kitchen or the app on your phone shows every pen at once. You catch the ewe circling and pawing, the water bag, the calf that's coming backwards — early, while you can still do something about it. You check the quiet pens without getting dressed and walking out into the cold to find nothing wrong. Fewer wasted trips, fewer losses, and a bit more sleep in the weeks you need it most. Set it up before the season, not during it The time to put cameras up is before the shed fills. Whether you're calving this autumn or planning ahead for spring lambing, get the gateway sited high and central and the cameras over the pens while you can still work in daylight and an empty shed. Add pens and sheds as the flock and herd grow — they just pair to the same gateway. What you need One HaLow access point / gateway, sited high and central (farmhouse gable, silo, or the main shed) and plugged into your broadband — or a single 4G router if the farm has no line, one SIM serving every camera. A HaLow camera over each pen you want eyes on, plus any outlying sheds up to a kilometre out. Your phone, or a screen in the house, to watch the lot.
