Getting Internet From Your House to Your Barn

Security cameras, smart feeders, streaming in the tack room — here's how to get real internet into a barn.

Barns are the classic outbuilding internet problem. They're too far from the house for Wi-Fi to reach reliably, too expensive to dig a trench to in most cases, and increasingly full of things that need internet: cameras watching foaling mares, smart waterers, automated feeders, smoke and temperature sensors, plus whoever's out there working who wants to stream music or take a video call.

Barns also have specific install headaches: metal roofs that block Wi-Fi, long linear layouts (a 200 ft run from the office to the wash stall), and a serious risk of lightning induction on any wire that leaves the building. Plan for all three.

For distances between ~100 ft and ~1500 ft — which covers almost every residential barn — a point-to-point wireless bridge is the default answer. If there's existing coax to the barn from an old cable run, MoCA is faster and easier.

What you'll typically use it for

  • Barn cameras (foaling, stall, exterior)
  • Smart waterers, feeders, and climate sensors
  • Office or tack-room workstation
  • Wi-Fi for trainers and boarders
  • VoIP phone in the barn office
  • Gate and access control

What to think about

  • Metal roofs and siding reflect Wi-Fi — mount the outdoor radio outside the barn, facing the house
  • Lightning risk is higher than with a house — surge protectors on both ends are non-negotiable
  • Large barns may need a second AP at the far end (e.g., wash stall or office)
  • Cameras benefit from PoE; choose a PoE switch on the barn side if you have more than one

Best solutions for this scenario

Ranked by typical best-fit for this kind of building and distance.

  1. 1
    Point-to-Point Wireless Bridge
    A pair of directional radios, one on each building. The default answer for distances where running a cable is impractical.
  2. 2
    MoCA Over Existing Coax
    If a coax cable already runs between the two buildings, a pair of MoCA adapters gives you gigabit+ ethernet over it.
  3. 3
    Direct-Burial Ethernet
    Run outdoor-rated Cat6 in conduit. Simple, rock solid, limited to 328 ft (100 m) without a switch.

UbiquitiPtp Radio~$180

Ubiquiti NanoStation 5AC Loco (NS-5ACL), 2-Pack

The default UniFi point-to-point pick. One box, both ends.

The most-installed outdoor PtP radio in the world. Two of them create a dedicated wireless bridge between buildings. Small, weatherproof, 24V passive PoE. Real-world throughput ~300–450 Mbps with clear line of sight. The 2-pack ships with both ends, mounts, and injectors.

Best for: Most house-to-barn / house-to-shop installs under 1500 ft.

  • Proven, huge install base, tons of community support
  • airMAX config is well-documented
  • Both units + mounts + PoE injectors in one box
  • Requires clear line of sight
  • 24V passive PoE (not 802.3af)

UbiquitiWifi Ap~$99

Ubiquiti UniFi 6 Lite Access Point (U6-Lite)

Default UniFi AP for inside the barn.

Standard 802.3af PoE Wi-Fi 6 access point. Once your bridge brings ethernet into the barn, plug this into a PoE switch or injector and you have fast Wi-Fi over the whole building. Manage via any UniFi controller (Cloud Gateway, UDR, Self-Hosted).

Best for: Indoor Wi-Fi coverage in the destination building.

  • Wi-Fi 6
  • Standard 802.3af PoE
  • UniFi controller (free) for config
  • Not outdoor-rated
  • PoE injector sold separately

UbiquitiSwitch~$200

Ubiquiti UniFi Switch Lite 16 PoE (USW-Lite-16-PoE)

16-port managed switch with 8 PoE+ ports. Barn-scale workhorse.

16 gigabit ports, 8 of them PoE+ (802.3at) up to 45 W total. Powers APs, cameras, and another PtP radio without needing separate injectors. Silent, wall-mountable, managed via UniFi. The default switch for any barn/outbuilding that needs more than a handful of ports.

Best for: Barn, shop, or ADU with several PoE devices.

  • 8 PoE+ ports in a silent box
  • Managed under UniFi with your router
  • 45 W PoE budget
  • Total PoE budget is modest — not for heavy cameras/APs everywhere
