The short answer
- With a HomeBase S380, the eufyCam S3 Pro records, alerts and detects people with no monthly fee, according to eufy [S1][S3].
- You must have a HomeBase S380. The camera has no storage of its own and doesn't work with the older HomeBase 2 [S1].
- eufy's paid plans are optional cloud backup, starting at $3.99/month for one device [S4].
- We couldn't find eufy stating in writing that live view is free, so that check is marked Unverified and scores zero for now.
What works with no plan
No-plan score: 4 of 5 (1 check not confirmed in writing yet, counted as zero)
| Feature | With no plan | Details and source |
|---|---|---|
| Live view | Unverified | eufy's no-monthly-fee page names notifications and playback, but not live view [S3], and the S3 Pro product page doesn't say either way [S1]. We haven't found eufy saying in writing that live view is free. Unverified |
| Local recording | Yes | The camera has no storage of its own. It records to the HomeBase S380 (HomeBase 3), which has 16GB built in and accepts a SATA hard drive up to 16TB [S1][S2]. eufy says this comes "without monthly fees" [S1]. |
| Motion alerts | Yes | eufy says you don't "pay a single cent more for instant notifications" [S3]. Notifications with thumbnail previews temporarily store the thumbnail in the cloud [S3]. |
| Person detection | Yes | eufy lists human detection and face and body recognition as HomeBase S380 features "without additional costs" [S3]. The camera itself pairs radar with PIR motion sensing and sends Stranger, Human and Vehicle alerts [S1]. |
| Clip history (24 hours+) | Yes | eufy says recordings stay local with "anytime, anywhere playback" and no monthly fee [S3]. When storage fills up, the HomeBase deletes the oldest recordings [S2]. |
What needs a paid plan
- Cloud Backup, an optional off-site copy of your recordings kept on a rolling 30-day basis [S4].
What the plan costs

| Plan | Covers | Price | 1 year | 3 years |
|---|---|---|---|---|
| eufy Cloud Backup Basic (1 device) [S4] | 1 device | $3.99/month or $39.99/year | $39.99 yearly $47.88 monthly | $119.97 yearly $143.64 monthly |

Storage, in eufy's numbers
- The HomeBase S380 has 16GB of storage that can't be removed. eufy estimates that's about 3 months of video for one camera recording 10 events a day at 20 seconds each [S2].
- You can add a SATA hard drive or SSD of up to 16TB. Once one is connected, all recordings go to it [S2].
- When storage is nearly full, the HomeBase deletes older recordings to make room. Mark clips you want to keep as favorites, or back them up [S2].
Things to know before you buy
- No 24/7 recording yet. eufy says the S3 Pro records motion events, takes periodic "24/7 Snapshot" photos in between, and that 24/7 recording is "in development" [S1].
- 2.4GHz Wi-Fi only [S1].
- Some data does touch the cloud. If you turn on notifications with thumbnail previews, eufy says those thumbnails are temporarily stored in the cloud [S3].
- eufy's store also sells a "Plus Member" membership for $15.00/month that includes cloud backup [S1]. It's a store membership, not a camera plan, so it isn't in our calculator.
