The eufyCam S4 Triple-Lens Outdoor Solar Security Camera Solo is designed to provide comprehensive outdoor surveillance through a combination of a 4K wide-angle bullet camera and a 2K dual-lens Pan-Tilt-Zoom camera. A fixed 130° view is provided by the upper 4K camera, while 360° coverage is delivered by the lower PTZ camera. With intelligent tracking, auto-framing, radar and PIR detection, detailed monitoring can be maintained across large outdoor areas.
Reliable year-round operation is supported by SolarPlus™ 2.0 and a detachable 5.5W solar panel. Only 1 hour of direct sunlight per day is required to keep the camera running, including during cloudy conditions. On-device AI is provided for person, vehicle, and pet detection, while 32GB of built-in storage is included and can be expanded up to 256GB through a microSD card.
When paired with HomeBase S380, additional BionicMind™ AI capabilities can be accessed to distinguish family members from strangers. Storage can also be expanded up to 16TB through HomeBase S380. For active security deterrence, radar and PIR sensors are combined with red and blue warning lights and a powerful 105 dB siren.
Key Features
2-in-1 Triple-Lens Bullet + PTZ Camera
A 4K wide-angle bullet camera and a 2K dual-lens Pan-Tilt-Zoom camera are combined in one outdoor security system. A 130° fixed overview and 360° rotating surveillance can therefore be provided simultaneously.
4K Wide-Angle Monitoring
A detailed 4K view is delivered by the upper camera, while a wide 130° field of view is maintained to monitor the surrounding area.
2K Dual-Lens Pan-Tilt-Zoom Camera
The lower dual-lens camera delivers 2K monitoring and can be rotated through 360°, allowing subjects and movement around the property to be followed.
Bullet-to-PTZ Tracking
When a person is detected by the bullet camera, the PTZ camera is automatically directed toward the subject. Tracking is then maintained with a sharp, centred close-up from distances of up to 50 metres.
Intelligent Auto-Framing
When additional subjects enter the frame, the view is automatically zoomed out so that everyone can remain visible.
SolarPlus™ 2.0 Power System
Year-round operation is supported by a 5.5W ultra-large solar panel and SolarPlus™ 2.0 technology. Just 1 hour of direct sunlight per day is required to keep the camera running, even on a cloudy day.
Detachable Solar Panel
Greater installation flexibility is provided through the detachable solar panel design, allowing positioning to be adjusted according to available sunlight and the installation area.
On-Device AI Detection
Smart person, vehicle, and pet detection is processed directly on the camera, allowing intelligent security features to be used even without a HomeBase.
Built-In and Expandable Storage
A total of 32GB of built-in storage is provided. Storage can be expanded up to 256GB through a microSD card, which is sold separately.
BionicMind™ AI with HomeBase S380
When HomeBase S380 is connected, BionicMind™ AI can be used to differentiate family members from strangers for more intelligent identification.
Up to 16TB Storage with HomeBase S380
HomeBase S380 includes 16GB of built-in storage and can be expanded up to 16TB, allowing significantly more security footage to be stored locally.
Radar + PIR Motion Detection
Radar and PIR sensors are used together to provide more accurate motion detection and help reduce unnecessary or false alerts.
105 dB Siren and Warning Lights
When a threat is detected within a configured zone or schedule, red and blue warning lights and a powerful 105 dB siren can be activated to deter potential intruders.
