eufy vs Reolink Security Cameras: Two Ways to Skip the Subscription

Lineups and prices

Prices published on each manufacturer's own store as of August 2026. Every model here is currently displayed below a higher compare-at price ($239.99 on the S340, $241.99 on the E340, $249.99 on the Argus 4 Pro, $219.99 on the TrackMix), so these are current promotional prices rather than stable list prices.

Both brands market these cameras as requiring no subscription for recording. Reolink also sells PoE (Power over Ethernet) versions of cameras like the TrackMix, plus hub and NVR options, which is the direction to look if you want a fully wired system; eufy's equivalent center of gravity is the HomeBase 3 hub with battery cameras around it.

Storage architectures

The storage philosophy differs even though both avoid fees.

eufy centralizes. Standalone cameras like the S340 carry 8GB of built-in eMMC storage, and eufyCam models write to a HomeBase 3 that ships with 16GB and accepts a hard drive up to 16TB. One hub, one archive, hidden indoors away from whoever might steal a camera.

Reolink decentralizes by default. The Argus 4 Pro and TrackMix each take a microSD card up to 512GB, which is far more per-camera storage than eufy's built-in 8GB, and both are compatible with Reolink's Home Hub if you later want central storage.

Practical consequences: per camera, Reolink gives you much more recording headroom without extra hardware. eufy gives you a single expandable archive but ties eufyCam models to the hub. In both cases footage lives in your house; if a thief takes the camera (or card), that footage can be lost, which is the standing trade-off of every local-first system in our no-subscription security cameras roundup.

Optics, detection, and power on paper

Optics. Reolink's Argus 4 Pro is the standout spec of the group: 4K across a 180 degree stitched dual-lens view, with ColorX low-light technology and an F1.0 aperture. eufy's answer is different geometry: the S340 pans 355 degrees and tilts 60, with a 3K wide lens and 2K telephoto, and the eufyCam S3 Pro lists 4K with MaxColor Vision for color night footage.

Detection. The eufyCam S3 Pro lists radar plus PIR detection with customizable zones. Reolink lists smart detection of people, vehicles, and animals on both models covered here, and the TrackMix adds auto-tracking that follows moving subjects with its 355 degree pan, 90 degree tilt, and 6x hybrid zoom.

Power and connectivity. Both flagships pair batteries with solar (the S340 ships with an adjustable, removable 2.2W panel; Reolink's Argus 4 Pro lists solar plus a non-removable battery charged over USB-C). Reolink publishes 2.4GHz and 5GHz Wi-Fi on both models covered here, and eufy publishes 2.4GHz and 5GHz Wi-Fi 6 on the E340. All of them still need Wi-Fi to be useful; for genuinely connection-free setups see security cameras without WiFi.

Which one fits you

Of the models covered here, by published specs and pricing:

Pick eufy if you want the most finished consumer experience: bundled solar, pan-tilt coverage, on-device AI, and a single expandable home archive on the HomeBase. It is the easier system to recommend to someone who wants to install it and stop thinking about it.

Pick Reolink if you want maximum per-camera storage (512GB microSD), the widest published field of view in this group (180 degrees at 4K), auto-tracking, or a path into wired PoE cameras and NVRs as your system grows. It rewards people who like to configure things.

Neither requires a subscription for recording, neither professionally monitors anything, and both are honest picks for the same buyer. The tiebreaker is usually ecosystem intent: eufy if this is a finished purchase, Reolink if this is the first piece of a larger wired system.
