Unlike some camera systems that require a dedicated hub, the E340 connects directly to Wi Fi and offers its core features and recording without a base station, while an optional HomeBase hub can be added later to expand local storage and AI features for larger Eufy security setups.
The S330 requires the HomeBase 3 hub to connect cameras, phones, and the network, which some reviewers see as an extra box and minor inconvenience even though the hub adds local storage, AI processing, and can be tucked unobtrusively on a shelf once the occasionally finicky first-time pairing is complete.
Reviews stress that the S3 Pro relies on the AC-powered HomeBase hub and an active network connection to store footage, so even though the cameras themselves are solar and battery powered, owners need backup power for the hub and router if they want recordings to continue during grid outages, and some users report that plugging the hub directly into the router can interfere with other connected devices, adding extra complexity to their home network.
