1 / 7eufy 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.
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 and cons
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.

What to know before buying
Listing details to confirm
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.
