Design & Build Quality
The Eufy SoloCam E40 features a clean, compact design that makes installation almost effortless. Since it operates on a rechargeable battery, there are no power cables to route, allowing you to mount it almost anywhere around your property.
Its IP65 weather-resistant housing protects the camera from rain, dust, and outdoor conditions, making it suitable for year-round use. The adjustable mounting bracket also makes it easy to position the camera for the best viewing angle.
2K Video Quality
The camera records in 2K Quad HD, producing noticeably sharper footage than standard 1080p security cameras.
The additional resolution makes it easier to recognize faces, monitor packages, and capture important details around your home. A wide 135° field of view also helps reduce blind spots, allowing one camera to monitor larger outdoor areas.
Night Vision Performance
The Eufy SoloCam E40 uses infrared LEDs to provide clear black-and-white video in low-light conditions.
Its night vision reaches up to approximately 25 feet (7.5 meters), providing dependable visibility for entrances, walkways, and gardens after dark. While it doesn’t include color night vision, the infrared performance remains sharp enough for everyday home security.
