Our take on the eufy Security Indoor/Outdoor Camera C31

The eufy C31 is a wireless indoor/outdoor security camera sold as a two-pack. It records 2K video, runs on a rechargeable battery, and works with Alexa and Google Assistant. It suits renters and homeowners who want local storage without a subscription, though it lacks the built-in spotlight and color night vision of pricier eufy models. Owners like the easy setup and clear daytime picture; some complain about motion alerts and night-time detail.
