Smart Video Doorbell Kit, Battery-Powered, 1080P, Wireless
eufy Video Doorbell C31 E8223311 – Smart 2K video doorbell with flexible power supply + eufy plug-in chime.
Always see who’s at the door with the eufy Video Doorbell C31 E8223311. This smart video doorbell combines sharp 2K image quality with motion detection, two-way audio, and local storage. Through the Eufy app, you’ll receive an instant notification when someone rings the doorbell or when relevant motion is detected near the front door.
The C31 can be used completely wirelessly with its removable 6,500 mAh battery, but it can also be connected to compatible existing doorbell wiring. This lets you choose the installation method that best suits your home.
Sharp 2K Images
The eufy Video Doorbell C31 captures visitors and events in crisp 2K resolution. Thanks to the 16:9 aspect ratio, you get a wide view of the area around your front door.
This way, you can easily check who’s ringing the doorbell and review events at the entrance via the eufy app.
See and talk to visitors instantly
When someone rings the doorbell, you’ll receive a notification on your smartphone and can immediately view the live feed.
Thanks to the built-in microphone and speaker, the C31 supports two-way audio. This allows you to communicate directly with the person at the door via the eufy app, even when you’re not at home.
Real-time video calls
The C31 supports real-time video calls. When a visitor rings the doorbell, a call with live video can appear on your smartphone.
This means you don’t have to navigate through multiple menus in the app first, allowing you to respond to a visitor more quickly.
Removable 6,500 mAh battery
The Video Doorbell C31 is powered by a powerful 6,500 mAh quick-release battery. The battery can be easily removed from the doorbell to charge it indoors.
This means you don’t have to remove the entire video doorbell from its mounting location when the battery needs to be charged.
A second compatible battery can be used as a spare, ensuring the doorbell is out of service for as short a time as possible while charging.
Wireless or Wired Installation
The C31 offers a choice of two installation options.
Want a simple installation without a power cable? Then use the included battery. If suitable existing doorbell wiring is available, the C31 can also be hardwired for a continuous power supply.
This makes the video doorbell suitable for both existing homes and situations where no doorbell wiring is available.
24/7 recording with wired power
With a suitable wired installation, the eufy Video Doorbell C31 supports 24/7 continuous video recording.
This allows you to continuously record what’s happening around your front door, so you’re not solely reliant on short, motion-activated clips.
5-second pre-roll
When powered by a wired connection, the C31 also supports 5 seconds of pre-roll for motion-triggered events.
This means the recording can start a few seconds before the actual event occurs. This gives you more context and lets you better see what happened before the motion alert was triggered.
Local storage
The eufy Video Doorbell C31 supports local storage via microSD. This allows you to store security footage locally without having to rely on a mandatory cloud subscription for basic storage.
The doorbell supports microSD cards up to 128 GB.
Compatible with HomeBase 3
Want to combine the C31 with other eufy security products? The video doorbell is compatible with the eufy HomeBase 3 (S380).
This allows the doorbell to become part of a more comprehensive eufy security system with centralized storage and additional features.
However, a HomeBase is not required to use the C31 as a video doorbell.
Voice Messages and Quick Replies
Can’t speak to a visitor right away? The C31 supports quick replies and voice messages.
This lets you use a preset response or give visitors the option to leave a message when you’re unavailable.
IP65 weather-resistant
The C31 is designed for use at the front door and has an IP65 rating. This means the housing is protected against dust and water jets.
This allows the video doorbell to remain installed outdoors in various weather conditions.
