## Questions & Answers

**Q: What chimes can Video Doorbell C31 pair with?**
A: The Video Doorbell C31 pairs with your existing chime, eufy HomeBase S280, S380, MiniBase Chime (T8023), Alexa. Note: It is not compatible with the original eufy Wi-Fi Chime (T8020), eufy Chime (T8740/T8742), or Apple HomeKit.

**Q: Is Video Doorbell C31 compatible with HomeBase 3?**
A: Yes, it is compatible with HomeBase 3. This setup provides expandable local storage, enhanced AI functionality, cross-device features, and more.

**Q: Why is my doorbell not working properly after binding?**
A: Ensure you have the latest app (version 5.0.22 or above) and check if the doorbell has received the latest software update.

**Q: Will Video Doorbell C31 support pre-record and 24/7 recording? Will my existing chime still work?**
A: Yes, C31 supports pre-record and 24/7 recording functions when powered by a 16-24V transformer (bypass chime). 24/7 recording is unavailable with HB2/Minibase, so use Solo or connect it to HB3 to enable this feature.

**Q: Why does my doorbell still show low battery or a decrease in battery level even after being wired?**
A: Using Existing Chime charges the doorbell slowly (6-7 days). High foot or vehicle traffic may still drain the battery. We recommend switching to "Bypass Existing Chime" mode.
