Video Doorbell C30 with HomeBase S380

The eufy Security Video Doorbell C30 is a battery-powered smart doorbell that captures 2K FHD video with a 4:3 expanded view. It connects via Wi-Fi and works with the included HomeBase S380 for local storage and smart home integration. The package suits homeowners who want a wire-free installation with no mandatory subscription fees.

Ideal for wire-free entrances.

This kit suits renters and homeowners who cannot run doorbell wiring and prefer battery operation with a 5,000 mAh cell. It supports Alexa and Google Assistant for voice control and pop-up video calls on a smartphone. Buyers who need hardwired power, continuous recording without battery recharging, or a mechanical chime connection should consider other options.

Local storage up to 128 GB on microSD

The system stores recordings on a microSD card with up to 128 GB capacity kept inside the HomeBase S380, eliminating monthly cloud fees. Footage remains under local control and the doorbell also supports quick responses and voice memos for visitors. This capacity determines how many days of motion events you can retain before overwriting.

Questions about this item

What are the exact dimensions of the C30 doorbell for mounting clearance?

The doorbell measures 6.2 inches high, 4.57 inches wide and 1.75 inches deep, so allow at least that footprint plus wiring space on your door frame.

Which step is often missed when pairing the doorbell with the HomeBase S380?

After charging the built-in 5,000 mAh battery, you must add the device in the eufy Security app before pressing the sync button on the HomeBase S380; skipping the app step leaves the doorbell unpaired.

When will the microSD card in the HomeBase S380 need replacement?

The HomeBase accepts cards up to 128 GB; replace the card when it reaches its write-cycle limit or if recordings show corruption, typically after several years of continuous 2K FHD recording.
