Dual-Antenna Strong Signal 2G/3G/4G Trail Camera

The Willfine 4.0P-CG is built with a dual-antenna LTE Cat.4 design, making it a dependable choice for weak-signal areas and remote off-grid locations. Its 57 pcs 940nm IR LED array — arranged in upper and lower lighting zones — delivers wide, balanced nighttime illumination. With 24MP images and 1080P video, it captures clear field intelligence day and night. Powered by 12 AA batteries for approximately 5–8 months of long standby time, and supporting MMS, SMTP, and FTP transmission, the 4.0P-CG is a reliable remote scouting tool for serious hunters, land managers, and wildlife monitoring professionals.

Dual Antennas — Engineered for Weak-Signal Country

Single-antenna cameras struggle in remote mountainous areas — unstable signal means dropped uploads, lost images, and broken real-time monitoring. The 4.0P-CG uses an LTE Cat.4 dual-antenna architecture: dual-path reception dramatically improves connection stability at the edge of cellular coverage, so your field intelligence actually arrives in real time.

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.
