TCL is expanding its lineup of smart home devices in China with the launch of the K7G Max smart door lock. Priced at 2,349 yuan ($324) and now available on JD.com, the K7G Max blends security tech with a sleek, connected design. And yes, it has a giant display on your door. The company had also introduced the K7G Plus variant earlier this year, but the Max steps things up with even more advanced features.
TCL K7G Max Specifications
The headline feature here is 3D facial recognition, powered by structured light tech similar to what you’ll find in Apple’s Face ID. TCL claims the system is smart enough to adapt to changes in lighting and appearance, thanks to continuous AI learning and eight different recognition algorithms working in the background. It supports up to 20 stored faces, along with multiple unlock methods including fingerprint, password, NFC, mechanical keys, and even remote unlocking from your phone.
The door lock doesn’t just scan faces. It also keeps an eye on what’s happening outside. The dual-camera setup pairs a 2MP front camera with a 160-degree field of view and a 1MP rear camera with a 120-degree wide-angle lens, giving you full coverage around your doorway. Video feeds can be viewed on a built-in 4.5-inch IPS touchscreen, which TCL calls a “cat-eye” display. That screen also ties into the company’s smart ecosystem, connecting with phones, TVs, and other displays for remote monitoring.
Powering all of this is a 6000mAh battery, which TCL says can last up to eight months on standby with the help of its T-Power energy management system. You’ll get low-battery warnings and visual indicators to avoid surprises, plus energy-saving modes if you want to stretch things further.
The K7G Max is wrapped in aluminum alloy and basalt glass, giving it a premium feel. It also pays attention to the little things. There’s noise reduction tech to keep things quiet when locking or closing the door.
Earlier this year, TCL expanded its TV lineup in Europe with the launch of the Q6C QD-Mini LED TV, offering a 144Hz refresh rate, Dolby Vision support, and mid-range pricing. The company also introduced the QM7K Mini LED TVs, featuring 2,800 dimming zones and a range of gaming-focused features.
