Excellent Replacement

Purchased this to replace my previous doorbell cam. This connected to the existing wiring and works with my old chime and it integrates with my eufy doorlock. That feature is a plus that I did not expect. I would highly recommend.

Replaced my nest doorbell camera with this!

Great device and easy to setup. I replaced my nest doorbell camera with this. It bolted right into my existing eufy ecosystem. Video and voice are very clear. This was a great decision
