eufy Security Video Doorbell Camera C31 – 2K FHD, Battery/Wired Power, 24/7 Recording

Overview

The eufy Security Video Doorbell C31 delivers 2K FHD clarity with a 4:3 aspect, showing visitors in a clear, head‑to‑toe view. The crisp daytime imagery and dependable night vision help you identify details from facial features to attire, enhancing awareness at your doorway.

Power and installation that fit your space

Designed for flexible setup, the C31 offers two power paths. Use the quick‑release 6,500 mAh battery for easy, cordless placement, or opt for a wired installation that draws power from your existing doorbell circuit. If you are wiring, ensure the battery is inserted and power is off during battery swaps or SD card changes; note that hardwiring may require bypassing your existing chime.

• Battery power enables fast, wire‑free placement.
• Hardwired mode provides continuous operation and 5‑second pre‑roll for motion events.

Real‑time communication and proactive alerts

When someone rings, a live video call appears on your phone for immediate viewing and interaction. If you’re away, you can send quick responses and invite visitors to leave voice messages, helping you stay informed without being onsite.

• Live video calls for instant two‑way communication.
• Quick replies and visitor voice messages for off‑site updates.

24/7 protection and smart home integration

Hardwire the doorbell to your existing circuitry for continuous recording and reliable power. The C31 works with eufy HomeBase S380 (sold separately) and HomeBase accessories, and is compatible with Alexa and Google Assistant for hands‑free control. When paired with HomeBase S380, you may leverage local storage options that can reduce reliance on cloud subscriptions, aligning with a no‑monthly‑fee approach when used together.

• Hardwired setup supports constant recording and steady power.
• Smart home compatibility with Alexa, Google Assistant, and HomeBase S380.

Why this matters for your entryway

The C31 combines a wide, head‑to‑toe view with reliable night vision, flexible power, and seamless smart‑home integration. It’s designed to adapt to different doorways and lighting conditions while offering practical ways to stay informed and respond when you’re not at home. While outcomes can vary, the combination of 2K quality, real‑time communication, and continuous monitoring presents a compelling option for proactive home entry management.
