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.

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.

Pros and cons

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.

What to know before buying

Listing details to confirm

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.

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.
Connectivity and reliability receive mixed reports, with both straightforward Wi-Fi setup and persistent connection issues described.
Value for money is also viewed differently by customers.
