AI-Powered 4K Smart Bird Feeder Camera

The BK750 fuses AI technology with the art of birdwatching. Its proprietary AI model identifies 10,000+ bird species worldwide at 95% accuracy, while Smart Filter intelligently screens out squirrels, cats, and other false triggers — every push notification is a real bird visit. The Sony 8MP sensor delivers 4K ultra-HD imagery in full color, day and night. Dual-band Wi-Fi (2.4GHz/5GHz) keeps live streaming lag-free. The 10000mAh battery plus solar compatibility means the camera stays on duty without interruption. Two-way audio lets you hear birdsong and interact — a truly immersive backyard birdwatching experience.

Industry-Leading: Proprietary AI, 10,000+ Species, 95% Accuracy

Most bird feeder cameras rely on third-party AI services with limited species coverage and inconsistent accuracy. The BK750 runs Willfine's own AI model, trained on vast real-world feeder footage, covering 10,000+ species globally and achieving 95% accuracy on common North American birds. Each time a bird arrives, the BirdKam App instantly pushes the species name, nature facts, and a photo — turning every feeding moment into a living nature lesson.

Core strengths

Smart Filter — Only the Alerts You Actually Want

Squirrels, cats, wind-blown branches — traditional PIR cameras treat them all the same, flooding your App with useless notifications. BK750's Smart Filter is specifically tuned to bird movement patterns, suppressing non-bird triggers so every alert is meaningful and trustworthy.

Sony 8MP Flagship Sensor + 4K Full Color, Day and Night

Unlike conventional night-vision cameras that shift to black-and-white in low light, BK750 uses white fill-lighting to deliver full-color images even after dark. The Blue Jay's iridescent blue and the Northern Cardinal's vivid red remain true to life at night. 4K resolution (7552 x 4248) resolves every individual feather filament.

10000mAh Ultra-Large Battery + Solar Compatible

The built-in 10000mAh lithium battery (DC 5V-2A charging) is compatible with solar panels (6V/2A or 12V/1.5A), providing sustained power for long-term unattended outdoor deployment and dramatically reducing recharge frequency.

Live Stream + Two-Way Audio

Launch a live stream anytime through the BirdKam App. The two-way audio system lets you hear the birds' calls and even play sounds back to them — a genuinely immersive connection with the wildlife in your own backyard.

Dual-Band Wi-Fi (2.4GHz / 5GHz)

Automatically selects the strongest available band, ensuring zero-lag live streaming and instant notifications even in complex outdoor Wi-Fi environments.

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.
