Installation: what UK buyers need to know
Runs on a quick-release battery pack, or in wired mode from existing doorbell wiring (8–24 V, more than 10 VA) with the battery kept installed and topped up, so it keeps working in a power cut. Works with your existing chime, or with eufy HomeBase S280/S380, the eufy MiniBase Chime (T8023), Alexa or Google Assistant devices; eufy says it is not compatible with the original eufy Wi-Fi Chime (T8020) or eufy Chime (T8740/T8742). If the installation needs new mains wiring or a new transformer, use a qualified electrician.
What the manufacturer claims
These are the manufacturer's own claims. COMANORA has not verified them; your results will depend on your home.
- eufy says the battery runs up to 6 months on a single charge (manufacturer claim; depends on use).
- eufy says 8 GB stores about 90 days of video, based on 30 clips of 20 seconds a day (manufacturer claim).
