eufy Security eufyCam S4 2-Cam Kit: Performance

Video Quality and Imaging

The eufyCam S4 2-Cam Kit excels in video quality, delivering crisp, clear, and highly detailed footage. The upper bullet camera features 4K resolution with a 130° fixed wide-angle view, ideal for covering large areas such as front yards or parking lots. The PTZ (Pan-Tilt-Zoom) camera, equipped with 2K resolution, is designed for smart tracking and zooming. This dual-camera setup ensures you capture both wide views and detailed images up to 164 feet away, making it a versatile option for various monitoring needs.

The combination of 4K and 2K cameras is a major selling point, as it allows users to get the best of both worlds. The bullet camera gives you a broad, panoramic view, while the PTZ camera provides more focused tracking with 8X hybrid zoom. This ability to zoom in on specific targets without losing image quality is particularly useful for monitoring moving vehicles or individuals.

Solar Charging and Power Efficiency

One of the most attractive features of the eufyCam S4 2-Cam Kit is its solar charging system. The 5.5W SolarPlus panel can keep the cameras charged with just one hour of direct sunlight per day, ensuring they remain operational year-round. This feature reduces the need for frequent battery replacements and simplifies maintenance. The detachable design of the solar panel also provides flexibility during installation, allowing you to adjust its positioning to maximize sunlight exposure.

While solar charging is a convenient feature, some users have reported mixed experiences with battery life. While some state that their cameras stay charged around 95% most of the time, others mention that the battery struggles to maintain charge, particularly in areas with less direct sunlight.

Motion Detection and Smart Features

The eufyCam S4 kit incorporates radar and PIR (Passive Infrared) sensors for motion detection, ensuring precise and accurate alerts. The cameras have the ability to differentiate between human and non-human motion, significantly reducing false alarms caused by animals or moving objects. This feature is especially important for areas with frequent activity, such as front yards or driveways.

The Cross-Cam tracking feature enhances the overall functionality, allowing the system to track subjects across multiple camera angles. Once the bullet camera detects a subject, the PTZ camera automatically locks onto the person or vehicle and follows them with smooth zoom and panning motions. This ability to track and zoom in on specific individuals ensures that important details are captured, whether it’s the face of a visitor or the license plate of a car.

Additionally, the 105 dB siren and red and blue warning lights provide an effective deterrent against intruders. The siren is loud enough to alert nearby individuals to a potential threat, while the flashing lights serve as a visual deterrent, further enhancing the security of your property.

Storage and Connectivity

The eufyCam S4 utilizes local storage with 16 GB of built-in memory, which can be expanded up to 16 TB, providing ample space for video recordings. The lack of a monthly subscription fee for cloud storage is a significant advantage, as users can save on long-term costs while ensuring their footage remains secure. The system is compatible with the eufy HomeBase S380, which enables 24/7 recording and access to snapshots. However, it’s important to note that other HomeBase models are not compatible with this camera system.

Ultra-stable wireless connectivity is ensured by the dual antenna design, which helps maintain a consistent signal even in larger homes or areas with multiple obstructions. This feature is crucial for seamless video streaming and reliable performance.
