4G Cellular Security Camera

The WILLFINE G100 keeps you connected to your property from anywhere — no Wi-Fi required. Built on 4G LTE Cat1.bis, it captures 12MP photos and 2.7K video, detects motion at up to 100 feet with a 100° PIR sensor, and uses AI to classify humans, vehicles, and animals. Manage everything live via the CalmGuard app — including two-way talk and real-time streaming.

Why 4G + AI Is the Right Stack for Outdoor Security

The vast majority of security cameras depend on home Wi-Fi — the moment you move beyond signal range to a remote cabin, farm, construction site, or property boundary, monitoring stops working entirely. Cameras that rely on raw PIR motion alerts, meanwhile, generate so many false positives from wind and foliage that users end up muting notifications altogether. G100 solves the "signal" problem with 4G LTE cellular and the "false positive" problem with on-device AI classification — humans, vehicles, and animals each get their own alert type, so every notification actually means something. Combined with 100 ft long-range detection, two-way talk, and solar-compatible power, your remote assets stay genuinely online and genuinely under control 24/7.

About Us

Twenty years ago, we set out to make outdoor cameras that actually work. We still do.

Since 2004, Willfine has engineered hardware behind some of the most trusted trail cameras on the market — pioneering GPRS connectivity before it was a category. Today, we're defining what's next: 4G-connected smart birding cameras, AI-powered wildlife monitoring, and off-grid security systems built for the real world.

Hardware alone doesn't build a brand. That's why we've built something most manufacturers can't offer: a complete, end-to-end technology stack.

Our team of 100+ R&D engineers handles every layer — custom hardware design, on-device AI (including species recognition), AWS and Oracle cloud infrastructure, and white-label mobile app development. When you bring us a product concept, you're not getting a factory. You're getting a technology partner who can take you from idea to market-ready in as little as three months.

Your vision. Our stack. Built to last.
