Pros and cons

Pros

Combines a fixed wide view with a rotating PTZ camera for both area coverage and closer tracking.
The listing claims built-in 32GB storage and microSD expansion up to 256GB without a monthly subscription.
Works standalone through a router, with HomeBase S380 support for additional features.

Cons

The camera uses Wi-Fi, so it is not presented as a cellular-connected system.
24/7 recording requires direct power and additional storage rather than relying on the solar setup alone.

What to know before buying

Listing details to confirm

Listing details are inconsistent about storage with HomeBase S380: one section states 16GB built-in storage expandable to 16TB, while standalone storage is stated as 32GB expandable to 256GB. Confirm the applicable configuration. Solar-runtime claims depend on sunlight, orientation and use. 24/7 recording requires direct 5V/2A power or higher, suitable storage, camera version V1.0.5.4 or later, and HomeBase version V3.7.2.8 or later when using HomeBase. HomeBase S380 and app updates are also specified for some features.

Customer feedback reports positive impressions of image quality and detection accuracy, while battery life, reliability, motion detection and value receive mixed reactions. Connectivity issues are also reported. These concerns matter for a solar Wi-Fi system intended for outdoor monitoring, where charging and a dependable network connection affect day-to-day use. The overall rating distribution is mostly positive but includes lower ratings, so it does not establish uniform performance.

Positive themes

Customers describe the camera quality and image as strong, including sharp 4K video.
Detection accuracy is also reported positively.

Negative themes

Connectivity issues are reported by customers.

Mixed feedback

Battery-life experiences vary, with some reporting that solar charging keeps the camera charged and others reporting poor battery life.
Reliability, motion detection and value for money receive mixed feedback.

Frequently asked questions

Does the eufyCam S4 have a fixed camera as well as PTZ?

Yes. The listing describes a fixed 4K wide-angle camera alongside a 2K dual-lens PTZ camera that rotates for 360° coverage.

Can it record continuously?

The listing says 24/7 recording requires direct power of 5V/2A or higher and additional storage. It also specifies camera version V1.0.5.4 or later, and HomeBase S380 version V3.7.2.8 or later when recording through HomeBase.

Does it require a HomeBase?

The listing says it can operate standalone when connected directly to a router, or work with HomeBase S380 for more features. It says HomeBase 2, HomeBase mini, HomeBase Professional, eufy NVR and Apple HomeKit are not currently supported.

How much storage is included?

The standalone feature description says 32GB built-in storage, expandable to 256GB by microSD card, which is not included. A separate HomeBase S380 description states 16GB built-in storage expandable to 16TB, so verify which configuration applies.
