CINMOORE's DB2 doorbell runs on Alibaba's Tongyi Qianwen to explain, not just record

CINMOORE has announced that its new-generation 4G dual-camera radar-vision fusion smart doorbell, the DB2, is now officially connected to Alibaba's Tongyi Qianwen large model. According to the company, three core capabilities — AI event summaries, visitor identity recognition and a daily highlight summary — are all provided by Qianwen. The doorbell's job has shifted from recording what happens at the door to telling users what happened and who showed up.

The change targets a gap that a decade of hardware progress did not close. Over that period, mainstream doorbells moved from million-pixel to 5-megapixel sensors, from single to dual cameras, from black-and-white to full-colour low-light night vision, and from Wi-Fi to 4G connectivity.

Yet the everyday problem persists. A typical home entrance can trigger dozens of events in a single day — deliveries, food couriers, neighbours passing by, a cat in the corridor. Users receive dozens of notifications and still have to dig through dozens of clips to answer simple questions: who was that, did my parcel arrive, did someone linger by the door.

A CINMOORE representative framed the shift bluntly: the industry keeps competing over who films more clearly, but what users actually need is not a clearer picture so much as a clearer answer. Seeing, the company says, is the camera's job; understanding is what counts as intelligence.

Technically, the DB2 splits the work. On the sensing side it uses CINMOORE's own radar-vision fusion approach: a 24GHz millimetre-wave radar first detects movement at the door, the camera then re-checks the frame, and recording starts only when the image is meaningful. Compared with conventional PIR infrared sensing, the company says this reduces false alerts caused by sunlight, heating and pets while lowering power draw.

The cognitive layer is handled by Qianwen. Radar and camera establish that something happened at the door; the model works out what it was, who was involved, and how to say it in a single sentence.

That translates into three features. Visitor identity recognition moves beyond a generic "person detected" alert to distinguish the apparent role or appearance of a caller, such as a courier or food delivery worker. AI event messages generate a one-line summary under each event — for example, a delivery worker leaving a parcel at 18:42 — so users can grasp the situation without opening the clip. The daily highlight summary stitches a day of door activity into a single video, a feature the company says has been well received.

On connectivity, the DB2 carries a built-in 4G module so it can run independently of home Wi-Fi, aimed at metal security doors, older buildings and homes where the router sits far from the entrance. Its two cameras are stacked vertically, the upper one watching visitors and the lower one watching packages left on the ground.

For solo residents, families with children and households with older adults, the point is less about recording than removing uncertainty. CINMOORE says the DB2 will go on sale on Douyin on September 19, with wider online channels to follow.
