Full product details
eufyCam S4 (4-Pack) is a cameras-only outdoor security bundle with four T8172 cameras and four detachable 5.5 W SolarPlus 2.0 panels; HomeBase S380 is not included. Each camera combines a fixed 4K lens with dual 2K PTZ lenses, bullet-to-PTZ tracking, auto-framing, radar and PIR motion detection, human, vehicle and pet detection, color and IR night vision, two-way audio, a 105 dB siren, a 10,000 mAh quick-swap battery, 32 GB built-in storage, and microSD expansion up to 256 GB (card not included). It can operate over 2.4 GHz Wi-Fi or pair with HomeBase S380 for additional capabilities including BionicMind face and stranger recognition, cross-camera tracking, and Smart Snapshot. HomeBase 2, HomeBase mini, eufy NVR, and Apple HomeKit are not currently supported. HomeBase S380 is sold separately and provides the HomeBase-assisted features described above. Continuous recording requires wired/direct power from a 5V/2A or higher adapter, camera firmware 1.0.5.4 or later, and either a microSD card for standalone recording or compatible HomeBase S380 hard-drive storage; HomeBase S380 firmware 3.7.2.8 or later is required when that architecture is used. Battery/solar-only operation is not a supported 24/7 configuration.
WHY THIS FOUR-PACK
Keep the wider scene while examining movement in detail
Each camera preserves a fixed overview while two PTZ lenses investigate activity, and four matching units extend that architecture across separate approaches.
Plan four distinct viewpoints
Place the four T8172 cameras at separate entrances, driveways or side paths, with a reliable signal and suitable power at each location.
Start without a base station
Each camera includes local storage and can use 2.4 GHz Wi-Fi; HomeBase S380 remains an optional expansion.
PROPERTY FIT
Where four coordinated wireless viewpoints may fit
A useful plan starts with sightlines, signal, mounting stability, sunlight, and the recording continuity each location requires.
Strong fit
Front entrance and driveway
- The challenge
- People and vehicles may approach from different directions.
- Why it may fit
- Two cameras can separate entrance and driveway duties while each retains fixed context and PTZ detail.
- Verify first
- Confirm cross-path motion, a stable surface, signal, and solar access at both positions.
Good fit
Side paths and property corners
- The challenge
- Narrow routes and corners can leave a single viewpoint with blind transitions.
- Why it may fit
- Matching cameras can cover separate approaches without mixing interfaces or capability sets.
- Verify first
- Test 2.4 GHz Wi-Fi or optional HomeBase signal at the exact mounting points.
Plan carefully
Four-zone residential plan
- The challenge
- Four locations multiply signal, charging, storage, and alert-management decisions.
- Why it may fit
- The four-pack provides one consistent camera architecture for each planned zone.
- Verify first
- Choose a wired PoE/NVR design instead when engineered, mission-critical 24/7 coverage is required.
FEATURES IN PRACTICE
Capabilities tied to real monitoring decisions
The useful question is not how many features are listed, but what each one changes and which dependencies apply.
CONTEXT + DETAIL
Fixed 4K plus dual 2K PTZ views
The fixed lens keeps the wider scene visible while two movable lenses can follow supported activity.
Requires: The combined lens wording does not mean one 16 MP sensor or one single 16 MP image.
DETECTION
Human, vehicle, and pet detection
On-device classification helps focus alerts around common residential activity types.
Requires: Settings, placement, motion path, and environmental conditions affect results.
NIGHT AWARENESS
Color and infrared night vision
The system can use color or infrared night viewing according to conditions and configuration.
Requires: Available light, range, obstruction, and placement influence image quality.
ACTIVE RESPONSE
Two-way audio and a 105 dB siren
Listen, speak, and use the camera siren as part of an informed response plan.
Requires: App access, network availability, and responsible local use.
OPTIONAL EXPANSION
HomeBase-enhanced recognition
Face and stranger recognition, cross-camera tracking, and Smart Snapshot are available through the compatible HomeBase path.
Requires: HomeBase S380, sold separately; not part of this cameras-only four-pack.
LOCAL STORAGE
Storage at each camera
Every camera includes 32 GB eMMC storage and supports microSD expansion up to 256 GB.
Requires: microSD cards are sold separately.
INSTALLATION + COVERAGE
Placement determines the useful coverage
Plan sightlines, cross-path motion, signal, mounting stability, sunlight, and any direct-power path before drilling.
Choose a stable 7–10 ft mounting zone
Use a safe, stable wall, ceiling, or top-mount surface at roughly 2–3 m with a useful approach view.
Test the exact network path
Confirm 2.4 GHz Wi-Fi or optional HomeBase S380 signal at every intended camera position before drilling.
Plan panel sunlight separately
Place each detachable solar panel where useful sunlight is realistic; shade, weather, temperature, activity, and settings affect charging.
Design wired-mode power before selecting 24/7 recording
Each continuously recording camera needs direct 5 V/2 A or higher power plus the correct storage and current software.
POWER PLANNING
Solar assists the battery; the site determines the result
Each camera pairs a 10,000 mAh quick-swap battery with a detachable 5.5 W SolarPlus 2.0 panel. No fixed runtime is promised.
BATTERY
Plan for variable demand
Activity, settings, signal, weather, temperature, and sunlight all affect runtime.
A full wired charge is approximately 6–8 hours with a compatible 5 V/2 A supply.
SOLAR
Treat the panel as assistance
The detachable panel can support charging where sunlight is suitable, but it does not create a guaranteed maintenance-free result.
Solar-only or battery-only operation is not a supported continuous-recording configuration.
STORAGE + RECORDING
Choose standalone or optional HomeBase storage deliberately
Each camera starts with local storage. Continuous recording adds direct-power, storage, firmware, and app requirements that must remain together.
IN EACH CAMERA
32 GB built in
Every T8172 camera includes 32 GB eMMC storage for local event recording.
Continuous recording requires direct 5 V/2 A or higher power and a microSD card or compatible HomeBase hard-drive storage, camera firmware V1.0.5.4 or later and the latest eufy app. HomeBase S380 recording also requires HomeBase firmware V3.7.2.8 or later.
STANDALONE EXPANSION
microSD up to 256 GB
Add a compatible microSD card for standalone wired-mode continuous recording. Use direct 5 V/2 A or higher power, camera firmware V1.0.5.4 or later and the latest eufy app.
microSD cards are not included.
OPTIONAL BASE PATH
HomeBase S380 hard-drive storage
When paired for continuous recording, HomeBase hard-drive storage becomes the default path.
HomeBase S380 and hard drive are not included.
Monthly plan context: Core local recording and on-device features require no monthly subscription. Optional cloud and other services may have separate fees and terms.
