Overview
Running on its own battery or hardwired to the old doorbell line, this eufy doorbell shows visitors in a tall head-to-toe frame and rings a live video call to your phone. Recording goes to an SD card or a HomeBase, with no subscription.
Choice of power is the strong point: a renter can stick with battery while an owner wires it for continuous recording. Quick replies and voice messages handle visitors when nobody is home. The indoor chime goes silent once wired, so a separate chime may be needed.
Who it's for
Renters can mount it on battery, and owners can wire it for round-the-clock footage. People who rely on their current chime should plan for a MiniBase Chime.
Pros and cons
- Battery or hardwired power
- No monthly fee
- Tall view shows packages at the door
- Pre-roll catches the start of events when wired
- Existing chime must be bypassed when wired
- SD card not included
- Continuous recording needs hardwiring
- 2.4GHz Wi-Fi only
Performance notes
Power source decides behaviour: on battery it records motion events, while wired power enables continuous recording and the pre-roll buffer. The tall frame aims the view down to the doorstep, so packages show up in the shot.
