Off-Grid Power

This upgrade takes security in the DIY pole barn to the next level — full 360° AI coverage using the Eufy S4 4K Security System with local NVR storage. Designed for serious protection without monthly fees or cloud reliance, the setup includes two fixed and two PTZ (pan-tilt-zoom) cameras powered entirely through PoE for rock-solid performance and constant uptime. Each AI-driven camera can identify, track, and zoom in on movement up to 164 ft away — all while processing footage locally for complete privacy.

What you’ll see in this video:
• Mounting the fixed and PTZ Eufy S4 4K cameras on all four barn corners
• Running and sealing PoE Ethernet cables with waterproof connectors
• Setting up the 8-channel, 2 TB NVR system with expandable local storage
• Configuring AI tracking, alerts, and patrol zones through the Eufy app
• Testing real-world tracking speed, night vision, and notification response
• Integrating backup power with the Anker C2000 portable station

Whether you’re securing a pole barn, workshop, or property perimeter, the Eufy S4 system proves that pro-level security can be fully local, subscription-free, and smart enough to protect itself — even when the power goes out.

PROJECT LINKS

Run Ethernet cables instead of relying on Wi-Fi—PoE gives you stable, high-quality video and power in one line.

Set your PTZ cameras to patrol mode overnight; the AI will auto-track movement and record only when activity is detected.

Eufy S4 Install

A full smart security upgrade for the DIY pole barn — four 4K cameras delivering complete 360° coverage. Local recording, no subscriptions, and full AI tracking make this system rock solid and private.

Fixed Corner Cameras

Two high-resolution fixed cameras watch the perimeter nonstop for total coverage. Mounted securely with PoE wiring, they provide stable, detailed visuals day or night.

PTZ Smart Cameras

The S4’s movable PTZ cameras pan, tilt, and zoom automatically to follow motion up to 164 feet away. AI tracking ensures nothing slips by — from vehicles to visitors.

Local NVR Setup

An 8-channel 2 TB NVR records everything locally, expandable to 16 TB for long-term storage. Easy setup with HDMI, mouse, and Ethernet — all plug and play. Mobile app works great!

AI Tracking

Real-time testing shows how fast the cameras detect and track motion — about five seconds from alert to action. Quiet motors, smooth movement, and precise subject lock-on.

Vision Patrol

Three viewing modes — infrared, spotlight, and auto streetlight — adapt to any lighting condition. In patrol mode, the PTZs sweep the area nightly, ready to zoom in when motion appears.
