eufy Video Doorbell C31（附電池組）

The 4:3 vertical view is a game changer—I can finally see the full package on the ground, not just the visitor's forehead. Setting it up took about ten minutes, and the battery pack means I haven't touched the wiring once since I hung it.

The 4:3 aspect ratio is what sold me—I can actually see packages sitting on the ground, not just heads and shoulders. Battery pack swaps out in seconds, so I never worry about the doorbell dying mid-week.

Installed it this morning and the 2K picture is noticeably sharper than my old doorbell, even in the afternoon glare. The 4:3 vertical view actually frames a person head-to-toe on my porch, which I didn't expect. Battery pack was a lifesaver since I don't have existing wiring.
