# eufy Security eufyCam S4 T8172 4K Solar Security Camera

T8172: The eufy Security eufyCam S4 is an outdoor wireless camera combining a fixed 4K wide-angle camera with a 2K pan-tilt-zoom camera, plus solar charging. Its dual-camera design aims to pair a broad overview with tracking close-ups, but the listing’s standalone and HomeBase storage claims differ and should be checked against your intended setup.

Prices and deal status are the latest recorded data, not a guarantee of availability. Confirm the price and availability with the store.

## At a glance

- The fixed upper camera is described as 4K with a 130° view, while the lower 2K PTZ camera rotates for 360° coverage.
- Bullet-to-PTZ tracking is claimed to follow detected people, with auto-framing described for subjects up to 50 metres away.
- A detachable 5.5W solar panel and SolarPlus 2.0 are claimed. The stated one-hour sunlight charging condition depends on direct, optimal sunlight and camera usage.
- The listing claims on-device person, vehicle and pet detection, a 105 dB siren, warning lights and 32GB built-in storage when used standalone.
- HomeBase S380 is described as adding BionicMind AI and expanded storage. The listing says 24/7 recording requires direct power and compatible software.

## Pros

- The separate fixed wide-angle and moving PTZ views can provide an overview and a closer tracking view from one camera installation.
- Solar charging may reduce routine charging where the panel receives suitable sunlight.
- Standalone operation and built-in storage are claimed, so a HomeBase is not presented as essential for basic use.

## Cons

- The claimed one-hour daily sunlight charging is conditional, so performance may not suit shaded locations or areas with limited direct sun.
- 24/7 recording requires direct power according to the listing, which limits an all-solar setup for continuous recording.

## Before you buy

- Listing details are inconsistent about storage: standalone use is described with 32GB built-in and expansion to 256GB by microSD, while HomeBase S380 use is described with 16GB built-in and expansion to 16TB. The 24/7 recording description also specifies direct power and a microSD card or hard drive, while another passage refers to HomeBase storage. Confirm the exact storage arrangement and required accessories for the chosen setup. Solar charging estimates are stated for optimal sunlight and average use, not guaranteed conditions.

## In the box

- / (Included): The listing’s explicit included-components field contains only this placeholder, so it does not identify the actual package contents.

## A good fit for

- Outdoor monitoring where a fixed wide view and a moving tracking camera are both useful.
- Buyers seeking solar-assisted power and local storage without requiring a HomeBase for standalone operation.
- Installations with suitable sunlight and Wi-Fi coverage.

## Less suited to

- Locations needing continuous recording without a direct power connection.
- Shaded sites where the panel cannot receive enough direct sunlight.
- Buyers who need the exact storage configuration or package contents to be confirmed from this listing alone.

## Customer feedback

Customer feedback describes sharp image quality and detection accuracy positively, but reports mixed experiences with battery life, reliability, motion detection and value. Some customers say the solar cell keeps the camera charged, while others report poor battery life, and connectivity issues are also mentioned. For buyers relying on solar charging or dependable remote alerts, those differing experiences matter alongside the listing’s conditional sunlight claims and Wi-Fi connection.
- Positive themes: Customers describe the camera’s quality and image as strong, including sharp 4K video.
- Positive themes: Detection accuracy is also described positively.
- Negative themes: Customers report connectivity issues.
- Mixed feedback: Battery life receives mixed feedback, including reports that solar charging maintains charge and reports of very poor battery life.
- Mixed feedback: Feedback on reliability, motion detection and value for money is mixed.

## Frequently asked questions

### Does the eufyCam S4 work without a HomeBase?
The listing says it can work as a standalone device connected directly to a router, with 32GB built-in storage. It describes HomeBase S380 as an option for additional features, though the listed storage details conflict, so confirm the setup before buying.
### Can it record continuously?
The listing says 24/7 recording requires direct power from a 5V/3A adapter or higher, compatible camera software, and storage. HomeBase use also requires a specified HomeBase software version.
### What views do the two cameras provide?
The listing describes an upper 4K camera with a fixed 130° view and a lower 2K dual-lens PTZ camera that rotates for 360° coverage.
### Is a microSD card included?
The listing says a microSD card is not included and describes it as an optional way to expand standalone storage. The package contents are not clearly identified.

## Offer details

- The claimed solar charging performance depends on direct sunlight, and the listing’s detailed estimate is based on optimal sunlight and average use.
- 24/7 recording requires direct power and storage, as well as compatible camera and, when applicable, HomeBase software versions.
