Home security has evolved beyond static cameras that simply record what's directly in front of them. The eufyCam S4 represents a breakthrough approach: a sophisticated dual-camera system that combines comprehensive area monitoring with intelligent subject tracking, all powered entirely by the sun.
This isn't just another solar security camera. The S4's innovative design features two distinct camera systems working in perfect harmony – a fixed 4K wide-angle camera that never misses the big picture, and a responsive 2K Pan-Tilt-Zoom camera that automatically follows movement with remarkable precision.
The first solar security camera that thinks and moves like a professional security operator

INTELLIGENT TRACKING SYSTEM

Dual-Camera Coordination

The S4's breakthrough lies in how its two camera systems work together. The upper 4K camera maintains constant surveillance of your entire property with its 130° field of view, ensuring nothing escapes detection. When movement is spotted, the lower 2K PTZ camera springs into action, rotating a full 360° to lock onto the subject with remarkable precision.
This coordination creates an unprecedented level of security coverage. You get both the wide situational awareness of a fixed camera and the detailed tracking capabilities of a PTZ system, eliminating the blind spots that plague traditional single-camera setups.
SOLAR POWER INNOVATION

SolarPlus™ 2.0 Efficiency

The S4's solar system represents a significant leap forward in renewable security technology. The 5.5W ultra-large panel is designed to capture maximum energy even in challenging weather conditions, requiring just one hour of direct sunlight to power the camera for an entire day.
The detachable solar panel design offers exceptional installation flexibility, allowing you to position the camera in the optimal location for surveillance while placing the panel where it receives maximum sun exposure. This separation eliminates the compromise between security coverage and power generation that hampers other solar cameras.

Legal guarantee

Minimum two-year legal guarantee protection for goods sold in the European Union.

Consumers can claim their rights under the legal guarantee of conformity, for example if goods:

  • do not match the description;
  • do not function as intended.

Sellers are liable for any lack of conformity which existed when the goods were delivered, and which becomes apparent within the legal guarantee period. Sellers in such a situation are required to offer:

  • free repair or free replacement;
  • in some cases, a price reduction or full reimbursement.

Some countries have a longer legal guarantee period. For second-hand goods, a shorter period may apply, but not less than one year.

For more information on your rights in a specific country, scan the QR code below or ask the seller. europa.eu/youreurope/guarantees

What to do if you receive non-conforming goods:

  1. Contact the seller as soon as possible to report the issue;
  2. Provide proof of purchase, such as a receipt, invoice, or bank statement.

Sellers and producers may also offer commercial guarantees, which apply independently from the legal guarantee. For example, you may see this GARAN label representing a commercial guarantee of durability offered by the producer at no additional cost and covering the entire good.
