eufy Video Doorbell C31

The eufy Video Doorbell C31 puts you face-to-face with whoever's at your door — even when you're not home. With 2K FHD resolution and a 4:3 expanded view, you get a clear picture from head to toe with no blind spots at the entrance. When the bell rings, a live video call pops up on your phone so you can speak directly with visitors in real time. If you're busy, set up quick responses or let visitors leave a voice memo — the door handles itself. Where the C31 stands out is its dual power flexibility. The 6,500mAh quick-release battery snaps in and out without tools — keep a spare and there's zero downtime for charging. Wire it in (16–24V, 30VA), and it unlocks 24/7 continuous recording with a 5-second pre-roll on every motion event so nothing gets missed. Human and motion AI detection keeps alerts accurate without drowning you in false alarms. All footage is stored locally on a microSD card up to 128GB — no cloud subscription, no monthly fees. Expandable to 16TB with the eufy HomeBase™ S380 (sold separately) for households that want centralised AI-powered management across multiple cameras. The C31 works with Alexa and Google Assistant and pairs with your existing doorbell chime, the MiniBase Chime, or HomeBase™ S280/S380.
