Reolink Argus 4 Pro vs eufy Cam 3: the two no-subscription 4K cameras compared
This is the closest fight in the category, because both brands refuse to hold your footage hostage. The eufy Cam 3 has an integrated solar panel and local AI face recognition through its HomeBase, which is genuinely clever — but the HomeBase is mandatory, and that pushes the real entry cost well above the sticker. The Argus 4 Pro works standalone with a microSD card and covers 180° against eufy's 135°, so one camera often replaces two. Pick eufy if you want a hub-based system you will grow into and value face recognition. Pick Reolink if you want each camera to stand on its own and you want the widest possible coverage per mount.

Prices & specsCommon questions
Do either of these need a monthly fee?
Neither does. Both store footage locally — Reolink on a microSD card or Home Hub, eufy on the HomeBase 3. Both offer optional cloud plans you can ignore.
Is the eufy HomeBase required?
For the Cam 3, yes — it is where recordings and the AI processing live. Factor its cost into any price comparison against a standalone Reolink.
