Devo G1 Video Smart Lock with Camera & Doorbell: 3-in-1 Integrated Security System
🔒 3-in-1 Integrated Security System: Imagine not needing a separate camera, doorbell, and lock—because the Devo G1 packs all three into one sleek package. It’s got a fingerprint scanner that actually learns your touch, a camera that sees in the dark (like, really sees), and a doorbell that won’t blast your ears off unless you want it to. Round-the-clock surveillance? Check, without the clutter.
🎤 Human Detection & 2-Way Audio: Ever wished your door could tell you, 'Hey, someone’s lurking'? Well, now it can. With tech that spots humans (not just your cat), it sends alerts straight to your phone. Plus, chat with whoever’s at your door—whether you’re in your pajamas or halfway across the world.
🔑 6 Flexible Unlocking Methods: Lose your keys? No problem. Forget your code? Also fine. This lock lets you in with a touch, a tap, a voice command (Alexa or Google, your pick), a card, or good ol’ fashioned keys. And the more you use your fingerprint, the smarter it gets—like a lock that’s also a quick study.
📱 Wi-Fi Connectivity & App Management: Control your lock from anywhere, because who hasn’t left the house and then panicked about whether they locked the door? The TUYA app lets you check, lock, unlock, and even give temporary access to the dog walker—all without leaving your couch.
⚡ Long Battery Life & Weather Resistance: Rain or shine, blizzard or heatwave, this lock doesn’t quit. A single charge lasts half a year, and it’s tough enough to handle whatever Mother Nature throws at it. (We’re talking IP65 waterproof—so yeah, it’s basically a lock in a raincoat.)
🛠️ Quick Installation & Support: If you can handle a screwdriver, you can install this in 15 minutes flat. No drilling, no drama. And if you hit a snag? There’s a year-long warranty and support team ready to help, day or night. Because peace of mind shouldn’t come with a complicated manual.
