Available to order
AT A GLANCE
A four-camera solar-assisted outdoor security kit combining fixed 4K context, dual 2K pan-and-tilt tracking, and HomeBase S380 local storage.
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
Choose this configuration when four separate outdoor viewpoints and one HomeBase-managed system fit the property better than disconnected purchases.
The fixed 4K view remains available while dual 2K pan-and-tilt lenses investigate supported activity.
Allocate identical T8172 cameras to distinct approaches instead of mixing separate camera types and controls.
The included HomeBase S380 enables face and stranger recognition and provides a second local-storage layer.
USE-CASE PLANNING
Placement quality depends on the sightline, signal, sunlight, and recording mode required at each location.
KEY FEATURES
These verified functions explain what the system can do and which dependencies matter.
CONTEXT + DETAIL
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 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
Those three categories are verified for on-device detection.
Important: Package detection is not verified for this model.
HOMEBASE
HomeBase S380 supplies the verified face and stranger recognition layer.
Important: The included HomeBase S380 and supported configuration are required.
AFTER DARK
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
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
The three-lens design separates broad awareness from movable detail without describing one sensor as a single 16 MP image.
The 4K lens keeps the wider scene in view.
The two 2K lenses pan and tilt to examine activity.
Auto-framing and cross-view handoff help follow supported subjects while conditions remain suitable.
INSTALLATION / COVERAGE
Plan sightlines, signal, solar access, mounting stability, and any direct-power path before drilling.
Use a suitable wall, ceiling, or top-mount surface around 2–3 m when site safety and sightlines permit.
Frame subjects moving across the sensing area and account for the practical direct-below blind area.
Confirm router or HomeBase S380 connectivity at the exact mounting point before drilling.
Position each detachable panel with minimal shade, generally equator-facing at roughly 30–45 degrees.
Use appropriate hardware, check for utilities, follow the Quick Start Guide, and use a qualified installer when needed.
POWER PLANNING
Every camera includes a 10,000 mAh quick-swap battery and a detachable 5.5 W SolarPlus 2.0 panel.
BATTERY
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
The 5.5 W panel can replenish the camera when the site provides suitable direct light.
Marketing references about one hour under optimal conditions; support recommends approximately one to two hours of adequate direct sunlight.
STORAGE & RECORDING
Choose storage around the desired recording mode and retention period.
PER CAMERA
Each camera also supports microSD expansion up to 256 GB.
microSD cards are not included.
HOMEBASE S380
HomeBase S380 supports a compatible expansion drive up to 16 TB.
A HomeBase expansion drive is not included.
Subscription context: Verified core local recording and on-device functions do not require a mandatory monthly plan; optional cloud or future services may differ.
