Eufy C30 vs C31 – Check Which One Is Best & Why?

Eufy C31 & Eufy C30 share many similarities, but there are also important differences, such as quality, performance, features, design, and connectivity. If you want the best one between them, I Would recommend the Eufy C31 rather than the Eufy C30. 

Why Do I Recommend The Eufy C31

  • The Eufy C31 features a dual power system that supports both battery and hardwired operation for flexible installation and uninterrupted power, while the Eufy C30 uses a built-in battery only with no option for wired use.
  • Eufy C31 comes with a 6,500 mAh removable battery for longer runtime and convenient swapping during recharging, whereas the Eufy C30 includes a smaller 5,000 mAh built-in battery.
  • It supports 24/7 continuous video recording to ensure complete event coverage at all times, while the Eufy C30 records only motion-triggered clips with potential gaps in footage.
  • The Eufy C31 includes a pre-roll recording feature to capture several seconds before motion is detected for better context, whereas the Eufy C30 lacks pre-roll support and records only after detection.
  • Eufy C31 uses a 4:3 aspect ratio with 2048×1536 resolution to provide a taller field of view that shows visitors from head to toe and packages on the ground, while the Eufy C30 uses a 16:9 aspect ratio.
  • It supports existing doorbell chime wiring for integration with standard indoor chimes, whereas the Eufy C30 does not connect to mechanical or digital chimes and relies only on mobile notifications.
  • The Eufy C31 includes a quick-release battery mechanism for easy removal and swapping without uninstalling the doorbell, while the Eufy C30 requires dismounting the entire unit to recharge its fixed battery.
  • Eufy C31 provides optional 5-second video previews through its wired setup to help users review motion events faster, compared to the Eufy C30 which lacks preview recording capability entirely.

Maybe the Eufy C30 price can make you comfortable because it’s a little bit cheaper than the Eufy C31. But you have to compromise all the above-mentioned features. Now the Decision is Yours. I hope it was helpful to choose the right one.
