# eufy Security Video Doorbell C31, 2K wireless camera with chime

The eufy Security Video Doorbell C31 is a wireless outdoor doorbell camera with a chime, 2K video claim and battery or wired power options. Its 24/7 recording and pre-recording are stated to require hardwiring and bypassing the existing chime, so the battery option does not provide those recording modes.

## At a glance

- A 6,500mAh quick-release rechargeable battery is described, with wiring also supported.
- The listing says 24/7 recording and five-second pre-roll require hardwiring to a 16-24V, 30VA transformer and bypassing the existing chime.
- Local microSD recording is described without a subscription, but the card is sold separately.
- A chime is listed as an included component, and the product description names MiniBase Chime compatibility.

## Pros

- Battery or wired installation gives buyers a choice of power setup.
- The listing describes phone video calls when someone rings, along with quick responses and voice messages.
- Local storage without a monthly subscription is offered through a separately purchased microSD card.

## Cons

- Continuous 24/7 recording and pre-roll are limited to the hardwired setup, which also requires bypassing the existing chime.

## Before you buy

- Listing details are inconsistent: the title calls the video 2K FHD while the technical field lists only “2k”. The chime is named in both the title and included-components field, but the kit details elsewhere are limited. The product description also lists HomeBase S380 and MiniBase Chime pairing, while other chimes have stated compatibility limits. Confirm the precise selected bundle and desired chime compatibility before buying. For 24/7 recording and five-second pre-roll, the listing specifies a 16-24V, 30VA transformer and chime bypass. It also says hardwiring involves DIY work and that the microSD card is sold separately.

## In the box

- Chime (Included): Named in the listing's included-components field.

## A good fit for

- Buyers wanting a doorbell camera that can run on a rechargeable battery or existing wiring.
- Households seeking phone alerts and local recording without a monthly subscription, provided they supply a compatible microSD card.
- Buyers who can meet the stated wiring and chime-bypass requirements for continuous recording.

## Less suited to

- Buyers who need 24/7 recording while using battery power alone.
- Buyers who need an included microSD card or certainty about compatibility with an unlisted chime.

## Customer feedback

Customer feedback highlights ease of setup, picture quality and avoiding a monthly subscription as positives. Battery life, connectivity, reliability and value receive mixed reports. For buyers choosing battery power, battery-life feedback is particularly relevant, while reports of connection problems matter for a Wi-Fi doorbell that relies on phone access. These are customer perceptions and do not establish how a specific installation will perform.
- Positive themes: Customers describe setup as easy and picture quality as clear in daytime and at night. Some appreciate that a subscription is not required.
- Mixed feedback: Battery-life experiences vary, from very good to poor.
- Mixed feedback: Connectivity and reliability receive mixed reports, with both straightforward Wi-Fi setup and persistent connection issues described.
- Mixed feedback: Value for money is also viewed differently by customers.
