WHY THIS KIT
Two views working together—not one lens choosing what to miss
The S4 architecture keeps a fixed wide view for orientation while its PTZ lenses investigate detail. For a buyer, that means a clearer sense of both what is happening and where it is happening.
Use two placements to cover different approaches
A two-camera kit lets you separate entrance, driveway, yard, or corner coverage instead of asking one viewpoint to solve every blind angle.
Build around local storage and included intelligence
Each camera records locally, and the included HomeBase S380 adds storage and HomeBase-assisted features. Core local recording and on-device features do not require a monthly plan; optional cloud services may cost extra.
PROPERTY FIT
Where this wireless two-camera kit earns its place
A useful camera plan starts with the approach path, signal quality, sunlight, and the level of recording continuity you actually need.
Strong fit
Front entrance + driveway
- The challenge
- People and vehicles can enter from different directions, making one moving viewpoint easy to pull away from the wider scene.
- Why it may fit
- A fixed contextual view and PTZ detail can work together while the second camera covers another approach.
- Verify first
- Test signal and aim for subjects to approach across—not directly beneath—the sensing area.
Strong fit
Front yard or property corner
- The challenge
- A corner often needs broad awareness plus detail from more than one direction.
- Why it may fit
- The wide fixed lens maintains context while PTZ tracking examines movement; the second camera can close a separate approach gap.
- Verify first
- Map both sightlines before mounting so the second camera closes a real approach gap instead of duplicating the first view.
Strong fit
L-shaped home or side yard
- The challenge
- Building geometry creates turns and narrow paths that one straight-ahead view may miss.
- Why it may fit
- Two wireless placements can divide the long and turning approaches without requiring camera Ethernet runs.
- Verify first
- Confirm 2.4 GHz Wi-Fi or HomeBase signal through exterior walls before drilling.
Good fit
Delivery approach
- The challenge
- The useful view is the person's approach and activity near the entrance, not simply the doorway.
- Why it may fit
- Human detection, wide context, PTZ detail, night monitoring, and two-way audio can support approach awareness.
- Verify first
- Human, vehicle and pet detection helps you follow activity around an entrance.
Conditional fit
Detached garage or outbuilding
- The challenge
- Distance, walls, and inconsistent sunlight can undermine a convenient wireless placement.
- Why it may fit
- Wireless operation and a detachable panel may reduce cabling when the site conditions cooperate.
- Verify first
- Verify signal at the exact mounting point and confirm a shade-free solar-panel position before treating the location as suitable.
Conditional fit
Small storefront or light-duty office exterior
- The challenge
- A small business may want flexible exterior awareness without a full wired build.
- Why it may fit
- Two cameras, local storage, HomeBase-assisted intelligence, audio, and deterrence can suit light-duty exterior monitoring.
- Verify first
- Choose a wired PoE/NVR design instead when continuous, engineered, many-camera, or mission-critical coverage is required.
FEATURES IN PRACTICE
Capability is useful only when it solves a real monitoring problem
These are the capabilities most likely to change how the system performs day to day, explained with their practical value and important dependencies.
AUTO-FRAMING
Keep multiple subjects in a useful frame
Auto-framing can account for up to five targets and prioritizes people, then vehicles, then pets when several supported target types are present.
Requires or note: Performance depends on positioning, view, distance, and environmental conditions.
ON-DEVICE DETECTION
Focus alerts on common outdoor movement
Human, vehicle, and pet detection helps distinguish useful activity categories without treating every motion event as the same.
Requires or note: Configure human, vehicle and pet detection for the areas you monitor.
HOMEBASE INTELLIGENCE
Add face and stranger context
The included HomeBase S380 adds BionicMind face/stranger recognition, cross-camera tracking, and applicable 24/7 snapshot functions.
Requires or note: HomeBase S380 and supported configuration are required for these HomeBase-assisted capabilities.
AFTER DARK
Choose color or infrared night monitoring
Use the spotlight for color night viewing or 850 nm infrared for discreet black-and-white viewing up to 32.8 ft / 10 m under suitable conditions.
Requires or note: Night results depend on placement, ambient light, obstructions, and scene reflectivity.
COMMUNICATE + DETER
Respond from the same system
Full-duplex two-way audio supports conversation, while red/blue warning lights and a 105 dB siren measured at 0.1 m provide configurable deterrence tools.
Requires or note: No deterrence feature prevents theft or crime, and the siren figure depends on the stated measurement distance.
PRIVACY CONTROL
Exclude sensitive areas from the view
Dynamic privacy zones can mask up to four areas per view, supporting more deliberate monitoring around neighboring or private spaces.
Requires or note: Mechanical movement, mounting changes, or calibration drift can require the zones to be checked and adjusted again.
HOW THE SYSTEM SEES
A fixed overview hands detail work to two PTZ lenses
Think of each camera as a lookout and an investigator sharing the same position: one preserves the map of the scene while the moving lenses examine action.
Keep the whole approach in view
The fixed 3840 × 2160 wide-angle view maintains broad context rather than turning away to follow one subject.
Investigate with dual PTZ lenses
The two 2688 × 1520 PTZ views can pan 360°, tilt from 0–70°, and use up to 8× hybrid zoom to examine the active part of the scene.
Track while preserving orientation
Bullet-to-PTZ tracking and auto-framing follow supported subjects while the fixed view continues to show where the action sits in the broader scene.
PLAN BEFORE YOU DRILL
Placement determines more than the camera specification
A strong installation combines useful sightlines, cross-path motion, dependable signal, a stable surface, and realistic sunlight for the detachable panel.
Start with a stable 7–10 ft mounting zone
Use a stable wall, ceiling, or top-mount surface at roughly 2–3 m where the camera has a useful approach view and installation can be completed safely.
Favor cross-path motion over the direct-below zone
Angle the camera so subjects move across the sensing area. A subject directly beneath the unit can enter a practical PTZ blind spot.
Test signal before drilling
Confirm 2.4 GHz Wi-Fi or HomeBase connectivity at the exact mounting point, with doors and exterior walls in their normal state.
Separate sensing distance from image detail
For placement, plan on PIR detection up to about 30 ft and radar detection up to about 40 ft. The 164 ft / 50 m detail-and-tracking figure is not a detection range.
Give the solar panel its own sightline
Place the detachable panel toward the equator with minimal shade and a roughly 30–45° angle, then account for seasonal sun and local weather.
Stay inside a safe installation boundary
Use suitable hardware for the surface, follow the Quick Start Guide and keep clear of utilities. Use a qualified installer for work at height, structural mounting or electrical work.
POWER PLANNING
Solar assists the battery; site conditions decide how much
Each camera pairs a 10,000 mAh quick-swap battery with a detachable 5.5 W SolarPlus 2.0 panel. The useful buying question is not a fixed runtime promise—it is whether your chosen location provides dependable charging conditions.
BATTERY
Plan for variable demand
Activity, settings, wireless signal, weather, temperature, and sunlight all affect runtime. The removable 10,000 mAh battery makes charging more practical, but no fixed day-or-month result is promised.
A full wired charge is approximately 6–8 hours with a compatible 5 V/2 A supply.
SOLARPLUS 2.0
Treat sunlight as a condition, not a guarantee
The detachable 5.5 W panel helps recharge each camera in direct sun. Plan for at least 1–2 hours of direct sunlight daily. About one hour can be enough only in optimal conditions; if the camera uses more power than the panel produces, the battery level will fall.
Shade, season, panel angle, weather, temperature, activity, settings, and signal can change the result; solar does not mean perpetual or maintenance-free power.
RECORDING CHOICES
Start local, then expand around your recording plan
Storage exists at both the camera and HomeBase levels. The best path depends on how much history you want, where you want it kept, and whether event recording or continuous recording is the goal.
IN EACH CAMERA
32 GB built in
Each camera includes 32 GB eMMC storage and supports microSD expansion up to 256 GB.
microSD card not included.
IN HOMEBASE S380
16 GB built in, expandable
The included HomeBase adds 16 GB built-in storage and supports a compatible expansion drive up to 16 TB.
HomeBase expansion drive not included.
Monthly plan context: Core local recording and on-device features do not require a monthly subscription. Optional cloud services or future features may carry a separate charge.

SPECIALIST CHECK
Is this the right system for your property?
The best fit is a property that benefits from flexible wireless placement, has reliable 2.4 GHz Wi-Fi or HomeBase signal, and can support the sunlight or direct-power plan its recording goals require.
VERIFY FIRST
Signal at the exact mounting point
Detached structures and distant corners are conditional on dependable 2.4 GHz Wi-Fi or HomeBase signal through the actual walls and distance involved.
VERIFY FIRST
Sunlight or direct power for the recording goal
Solar contribution varies. Continuous recording needs direct 5 V/2 A or higher power, compatible storage, and the required software versions.
IMPORTANT LIMIT
PTZ and privacy settings need real-world checks
A direct-below blind area can affect tracking, and dynamic privacy zones may need recalibration after movement, mounting changes, or mechanical drift.
NOT THE BEST FIT
Very large or mission-critical sites
Choose a wired PoE/NVR design instead if you need engineered, many-camera continuous coverage. This wire-free solar kit is built for a different job.
QUESTIONS BEFORE PURCHASE
Plan the system with the dependencies in view
Concise answers to the questions that most often change placement, storage, compatibility, or purchase expectations.
The cameras use 2.4 GHz Wi-Fi directly to a router or through HomeBase S380. HomeBase uses Ethernet to the router. The cameras themselves do not use Ethernet or PoE, and they have no cellular connection.
Yes, when each camera has direct 5 V/2 A or higher power, compatible storage, camera firmware 1.0.5.4 or later, and the latest eufy app. When HomeBase is used, HomeBase firmware 3.7.2.8 or later is also required. Solar/battery operation alone should not be mistaken for continuous recording.
No. The S4 provides up to 8× hybrid zoom, not 8× optical zoom.
The cameras identify people, vehicles and pets. Configure detection areas and alerts for each camera position.
The camera is IP65-rated. Documentation for the same camera model in another market lists an operating range of −4°F to 131°F and a charging range of 32°F to 113°F. Check guidance for your region before installation.
Yes. eufyCam S4 (T8172) supports Amazon Alexa and Google Assistant; available commands depend on the connected service and current software. Apple HomeKit is not currently supported.
Use the HomeBase S380 included with this kit and supported software for the HomeBase-assisted features described here. HomeBase 2/S280, HomeBase mini and eufy NVR are not supported. Available HomeBase features depend on the base model and software.
No monthly plan is required for core local recording and on-device features. Optional cloud services or future features may carry a separate charge.
Plan a stable camera position around 7–10 ft / 2–3 m, favor cross-path motion, test signal before drilling, and account for the direct-below PTZ blind area. Place the panel toward the equator with minimal shade at about 30–45°, then follow the Quick Start Guide and site-safety requirements.
Up to four privacy zones per view can mask selected areas. Because PTZ movement, mounting changes, or mechanical calibration drift can alter alignment, review and recalibrate the zones when the physical setup changes.
This kit has a 2-Year ClearVero™ Product Warranty from delivery for eligible verified defects in normal use, subject to the full coverage and exclusions. eufy's separate U.S. policy lists a 12-month limited manufacturer warranty for security cameras, subject to its own eligibility rules; it does not replace or extend ClearVero coverage.
Request an eligible return within 30 days of delivery and get authorization before sending it. For a non-defective return, you pay return shipping; an eligible opened or tested item may carry a 15% restocking fee after inspection. For a verified defect, damage, or wrong item, approved return shipping is covered when needed and no restocking fee applies. See full return terms. This guarantee is separate from the warranty. U.S. delivery is estimated within 7 business days after normal 1–3-business-day processing, not guaranteed; see the shipping policy and checkout for costs.
