The eufy Video Doorbell C31 (model T8223) is a single-camera video doorbell that runs on a removable 6,500mAh battery or on existing doorbell wiring. It records 2K (2048×1536) video in a 4:3 aspect ratio, detects people and motion, and has two-way audio. A video call pops up on your phone when someone presses the button, and you can set quick responses or let visitors leave voice messages. When it is hardwired with the existing chime bypassed, it supports 24/7 continuous recording and 5-second pre-roll; on battery power, it records motion events. Recordings are saved to a microSD card of up to 128GB (not included) or to a compatible eufy HomeBase, with no monthly fee for local storage. It is rated IP65, connects to 2.4 GHz Wi-Fi, and works with Alexa and Google Assistant, but not Apple HomeKit. It is a different product from the eufy Wired Cam C31 security camera.
1. Great for
Front doors with existing doorbell wiring — When hardwired with the existing chime bypassed, it records 24/7 and keeps 5 seconds of pre-roll before each motion event.
Homes without doorbell wiring — It runs on a removable 6,500mAh quick-release battery charged over USB-C, and a spare battery pack lets you swap instead of waiting for a recharge.
Keeping recordings at home without a monthly fee — It saves video to a microSD card of up to 128GB (not included) or to a eufy HomeBase, and local recording needs no subscription.
Answering the door from your phone — A video call pops up when someone rings, with quick responses and voice messages when you can't talk.
Adding a doorbell to an existing eufy HomeBase — It works with HomeBase 3 (S380), HomeBase 2, and HomeBase mini; HomeBase 3 supports a 2.5-inch hard drive of up to 16TB (sold separately).
2. Not ideal for
Recording 24/7 while keeping your existing indoor chime — 24/7 recording and pre-roll require bypassing the existing chime; to hear a chime indoors in that setup, use a eufy HomeBase or an Alexa Echo device. 24/7 recording is not available with a MiniBase Chime.
Package alerts or a second, downward-facing camera — It has a single camera, and package detection is not supported.
Apple Home (HomeKit) households — It does not support Apple HomeKit; it works with Alexa and Google Assistant.
1. Which eufy video doorbell should I choose: C31, C30, or E340?
Choose the Video Doorbell C31 if your home has existing doorbell wiring and you want 24/7 recording and 5-second pre-roll; it can also run on its removable 6,500mAh battery. The Video Doorbell C30 runs on a 5,000mAh battery only and does not support hardwiring, 24/7 recording, or pre-roll, so it suits homes without doorbell wiring. The Video Doorbell E340 adds a second camera, package detection, and 8GB of built-in storage, and it can run on battery or doorbell wiring. The C31 and C30 both record 2K video to a microSD card of up to 128GB (not included).
2. Is the eufy Video Doorbell C31 the same as the eufy Wired Cam C31?
No. The Video Doorbell C31 (model T8223) is a front-door video doorbell that runs on a battery or doorbell wiring. The eufy Wired Cam C31 is a separate security camera with its own specifications and compatibility. When checking specs, accessories, or support articles, look for "Video Doorbell C31" or model number T8223.
3. Does the Video Doorbell C31 support 24/7 recording, and will my existing chime still ring?
Yes, when it is hardwired and set to "Bypass Existing Chime." In that mode, it supports 24/7 continuous recording and 5-second pre-roll, and your existing chime no longer rings; you can use a eufy HomeBase or an Alexa Echo device as the chime instead. 24/7 recording is not available when the doorbell is used with a MiniBase Chime (T8023). If you choose "Use Existing Chime," your chime keeps ringing, but the doorbell receives only a low charging current, and 24/7 recording and pre-roll are not available. On battery power alone, it records motion events. 24/7 recording is also unavailable when the doorbell is connected to HomeBase 2.
4. What do I need to hardwire and install the C31?
It connects to existing doorbell wiring with a 16–24V AC doorbell transformer rated between 10VA and 40VA, and the battery pack stays inserted in either wired mode. The box includes a Chime Bypass Jumper, a 15-degree mount for angling the doorbell, an extension cable, and a mounting bracket. Turn off power at the circuit breaker before connecting the wires; on brick, concrete, or stucco, you will need a power drill with a 15/64" bit. The doorbell connects to 2.4 GHz Wi-Fi.
5. How long does the battery last, and how do I charge it?
The C31 uses a removable 6,500mAh quick-release battery pack, and eufy lists a 180-day battery life; actual battery life varies with use. Take the pack out and charge it with the included USB-C cable, or keep a spare pack (sold separately) to swap in. The battery ships at about 80%, so charge it fully before first use.
6. Where does the C31 store recordings, and do I need a subscription?
When it is connected directly to your router, it saves recordings to a microSD card of up to 128GB, which is not included. When it is connected to a eufy HomeBase, it saves recordings to the HomeBase. When it is used with a MiniBase Chime (T8023), recordings can be saved to a microSD card inserted in the chime. Local recording requires no monthly subscription, and videos are encrypted with AES-256.
7. Which eufy HomeBase works with the C31?
It works with HomeBase 3 (S380), HomeBase 2, and HomeBase mini, and it also works on its own without a HomeBase. With HomeBase 3, recordings are stored on the HomeBase, which has 16GB of built-in storage and supports a 2.5-inch SATA hard drive of up to 16TB (sold separately), and the doorbell works with BionicMind, Modes, and Automation. When connected to HomeBase 2, 24/7 recording is not available. Keep the HomeBase within 30 feet of the doorbell.
8. What chimes work with the C31?
It works with an existing mechanical doorbell chime when hardwired in "Use Existing Chime" mode, a eufy HomeBase S280 or S380 speaker, up to 8 MiniBase Chimes (T8023), and Alexa Echo devices. It does not work with the original eufy Wi-Fi Chime (T8020) or eufy Chime (T8740), and a Google Home Mini cannot be used as a chime. The MiniBase Chime can store recordings on a microSD card inserted in the chime; 24/7 recording is not available with a MiniBase Chime.
9. Does the C31 work with Alexa, Google Assistant, or Apple HomeKit?
It works with Amazon Alexa, which can show the live view on an Echo Show and announce doorbell presses, and with Google Assistant, which can show the live view on Google Chromecast. It does not support Apple HomeKit, SmartThings, Home Assistant, or IFTTT. It also works with the eufy Smart Display E10.
10. What does the C31 camera see?
It records 2K video at 2048×1536 in a 4:3 aspect ratio with a 160° field of view. Its night vision is not in color. It detects people and motion; package detection and face recognition are not supported.
11. Why isn't my doorbell working properly after setup?
Make sure the eufy app and the doorbell firmware are both updated to the latest version.
12. Does Video Call work when the C31 is connected to HomeBase 3?
Yes. A video call pops up on your phone when someone presses the button, whether the doorbell is used on its own or connected to HomeBase 3.
