The EufyCam S3 Pro Expansion 3-Pack consists of three additional IP security cameras designed to expand your existing Eufy security system. These cameras require a HomeBase 3 unit for operation and are not compatible with HomeBase 2 or standalone use. Each camera records videos in sharp 4K resolution and features enhanced color night vision for clear monitoring in low light conditions. A significant improvement includes a larger integrated solar panel that fully charges the battery with just one hour of direct sunlight, providing double the charging speed compared to previous models. Recorded footage is stored directly on the HomeBase 3, eliminating the need for additional SD cards or cloud subscriptions. Advanced AI detection technology distinguishes between people, animals, and objects, thereby reducing false alarms from non-threatening movements like birds or foliage. For optimal performance during extended periods of limited sunlight, occasional manual charging may be required. The system prioritizes privacy through local storage and features a reliable, weather-resistant construction suitable for outdoor use.
