Customers are saying

Customers consistently note the amazing video quality, excellent tracking performance, and surprisingly easy setup, alongside its exceptional battery life and broad coverage. Many also appreciate its advanced features like superior motion detection, AI-guided recording, automatic zoom, and effective solar panel charging, complemented by good night vision. The primary concern raised by users is the camera's size, which some find to be less than discreet.

    Love it. Replacing a Lorex system with a eufy system. I would argue that the video quality is a bit better on my Lorex system. But the Eufy system is a smart system. With face, pet, package recognition. Just way friendlier.

    The lithium batteries struggle to charge in the cold winter weather, and the AI facial recognition does not work 95% of the time. other than that the cameras, and base station have worked well so far.
