What owners say

Owners of both doorbells praise sharp 2K video, a tall view that catches packages on the ground and an easy install, wired or wireless. Arlo Video Doorbell 2K (2nd gen) owners single out accurate person, package and vehicle recognition, a friendly app, a small weatherproof body and prompt notifications. Their main complaint is that cloud storage, smart alerts, video history and even motion zones need an Arlo Secure plan, plus over-sensitive alerts and that it does not work in many countries outside the US. Eufy Video Doorbell E340 owners single out the free local recording, the second camera pointed at the doorstep and accurate package and person detection. They complain that it needs a separate chime to ring indoors, about a clunky app with the occasional false delivery alert, a bulky body and only adequate battery life.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
