Users of eufy smart home cameras (eufyCams) have been seeing the camera feeds of strangers, even in other countries. The controls of affected cameras are also accessible. eufyCams allow users to access their camera feeds anywhere in the world over the Internet.
This feature (in any brand of camera) obviously poses a privacy and security risk if you care about being stalked or having your home broken into. If you’re going to use a wireless surveillance camera, disable cloud functionality and configure it to operate offline only.
I would recommend re-configuring your eufyCam setup to use only local storage for now, and also ensuring that your cameras are not recording potentially sensitive information, as that information could be stolen remotely by fraudsters or identity thieves watching your feed.
