Full product details
The eufyCam S4 4-Cam Kit (E81721W2) combines four T8172 outdoor cameras with HomeBase S380. Each camera pairs a fixed 4K lens with dual 2K pan-and-tilt lenses, a quick-swap 10,000 mAh battery, a detachable 5.5 W solar panel, 32 GB of built-in storage, color and infrared night vision, two-way audio, warning lights, and a siren. The system supports on-device human, vehicle, and pet detection, while face and stranger recognition require HomeBase S380. The included HomeBase provides 16 GB of built-in storage and supports expansion up to 16 TB; no hard drive or microSD card is included. Continuous recording requires compatible storage, current firmware and app versions, and a separate continuous 5 V / 2 A or higher power source for every camera. Performance, solar replenishment, detection, tracking, storage duration, integrations, and battery life vary with settings, placement, weather, network conditions, activity, and firmware.
WHY CHOOSE IT
Why choose the coordinated four-camera kit?
Choose this configuration when four separate outdoor viewpoints and one HomeBase-managed system fit the property better than disconnected purchases.
Plan four viewpoints together
Allocate identical T8172 cameras to distinct approaches instead of mixing separate camera types and controls.
Centralize compatible intelligence
The included HomeBase S380 enables face and stranger recognition and provides a second local-storage layer.
USE-CASE PLANNING
Plan each camera around a real approach path
Placement quality depends on the sightline, signal, sunlight, and recording mode required at each location.
Strong fit
Entrance and driveway
- Need
- Separate people and vehicle approaches may need more than one viewpoint.
- Why it fits
- Multiple placements can divide coverage while each camera keeps fixed context and movable detail.
- Verify first
- Test signal and frame subjects moving across the sensing area.
Strong fit
Side yard and property corner
- Need
- Turns, corners, and narrow paths can create blind angles.
- Why it fits
- Wireless camera placement can distribute coverage without camera Ethernet runs.
- Verify first
- Confirm a stable mounting surface and exact HomeBase or router signal before drilling.
Verify first
Detached structure
- Need
- Distance, exterior walls, and uneven sunlight can reduce reliability.
- Why it fits
- Battery and detachable solar-panel operation may reduce cabling where site conditions are suitable.
- Verify first
- Verify signal and shade-free panel positioning at the final mounting point.
Plan as a system
Four-zone home layout
- Need
- An entrance, driveway, side path, and rear approach may each need a dedicated viewpoint.
- Why it fits
- The four-camera package lets the buyer allocate one identical T8172 camera to each planned zone.
- Verify first
- Confirm signal, sightline, mounting surface, and sunlight at all four positions before installation.
KEY FEATURES
Capabilities tied to practical buying decisions
See what the four-camera system can do and where HomeBase S380, power, or storage changes the result.
CONTEXT + DETAIL
Fixed 4K and dual 2K views
Each T8172 camera combines one fixed 4K view with two 2K pan-and-tilt views.
Important: The up to 8× zoom is hybrid, not optical.
TRACKING
Auto-framing and handoff
Auto-framing can frame up to five supported targets, with priority given to people, then vehicles, then pets.
Important: Handoff may take up to 2.5 seconds; obstruction, target exit, or the direct-below blind area can interrupt tracking.
DETECTION
Human, vehicle, and pet categories
On-device detection identifies people, vehicles and pets.
Important: Configure detection zones and alerts for each camera position.
HOMEBASE
Face and stranger recognition
HomeBase S380 adds face and stranger recognition.
Important: The included HomeBase S380 and supported configuration are required.
AFTER DARK
Color and infrared night vision
Spotlights support color night viewing; four 850 nm IR LEDs support infrared visibility up to 10 m / 32.8 ft.
Important: Results vary with placement, ambient light, obstruction, and reflectivity.
COMMUNICATION
Full-duplex audio and deterrence
Dual-microphone noise reduction supports two-way audio; warning lights and a siren add configurable deterrence.
Important: The 105 dB siren figure is measured at 0.1 m and does not guarantee prevention.
HOW EACH CAMERA SEES
A fixed view works beside two pan-and-tilt views
The three-lens design separates broad awareness from movable detail without describing one sensor as a single 16 MP image.
Fixed overview
The 4K lens keeps the wider scene in view.
Movable detail
The two 2K lenses pan and tilt to examine activity.
Supported tracking
Auto-framing and cross-view handoff help follow supported subjects while conditions remain suitable.
INSTALLATION / COVERAGE
Verify placement before mounting
Plan sightlines, signal, solar access, mounting stability, and any direct-power path before drilling.
Choose a stable 7–10 ft position
Use a suitable wall, ceiling, or top-mount surface around 2–3 m when site safety and sightlines permit.
Favor cross-path motion
Frame subjects moving across the sensing area and account for the practical direct-below blind area.
Test 2.4 GHz signal
Confirm router or HomeBase S380 connectivity at the exact mounting point before drilling.
Plan solar separately
Position each detachable panel with minimal shade, generally equator-facing at roughly 30–45 degrees.
Follow site-safety limits
Use appropriate hardware, check for utilities, follow the Quick Start Guide, and use a qualified installer when needed.
POWER PLANNING
Battery and solar performance depend on the site
Every camera includes a 10,000 mAh quick-swap battery and a detachable 5.5 W SolarPlus 2.0 panel.
BATTERY
Runtime is variable
Activity, settings, wireless signal, weather, temperature, and solar input all influence runtime.
A wired charge is approximately 7–8 hours with compatible 5 V / 2 A power.
SOLARPLUS 2.0
Plan around direct sunlight
The 5.5 W panel can replenish the camera when the site provides suitable direct light.
Aim for about 1–2 hours of direct sunlight daily for typical use. Solar charging varies with shade, season, panel angle, weather, temperature, settings, activity and wireless signal.
STORAGE & RECORDING
Local storage starts in the cameras and HomeBase
Choose storage around the desired recording mode and retention period.
PER CAMERA
32 GB built in
Each camera also supports microSD expansion up to 256 GB.
microSD cards are not included.
HOMEBASE S380
16 GB built in
