This add-on eufy Video Doorbell Dual uses a 2K front camera and a second downward-facing camera to cover visitors and parcels. Radar and PIR sensing support motion detection, while eufy's package and waiting detection features can generate relevant alerts. It also provides HDR video and two-way audio through the eufy app.

A compatible eufy HomeBase is required and is not included, so the add-on cannot operate by itself. It is battery-powered and records motion events rather than continuous 24/7 video. Existing low-voltage doorbell wiring may maintain the battery and operate a compatible mechanical chime, but it does not turn the product into the separately sold wired model. Check HomeBase and chime compatibility before purchase.
