Power your setup your way

The C31 supports dual power options for flexible installation. Use the quick-release 6500 mAh rechargeable battery for portable placement or hardwire to your existing doorbell wiring for a steady power source. When switching power, follow the safety notes about turning off power at the breaker and bypassing the chime if needed.

• 6500 mAh battery enables cordless placement
• Hardwired option provides continuous power

Around-the-clock protection with 5 second pre-roll

Hardwired operation unlocks 24/7 recording and a 5 second pre-roll for motion events, giving you richer context when reviewing footage. This helps you capture activity from moments before an alert activates.

• Continuous recording for uninterrupted coverage
• 5 second pre-roll for better event context

Smart, compatible, and budget-conscious

Designed to fit into the eufy ecosystem, the C31 works with HomeBase S380 and supports Alexa and Google Assistant. Local storage via HomeBase minimizes reliance on monthly cloud fees, aligning with a straightforward setup and ongoing control.

Included is an extra rechargeable battery pack to extend use, and DIY friendly setup guidance notes. If you choose hardwired installation, you may need to bypass your existing chime to ensure proper functionality.
