eufy Security eufyCam S4 4-Cam Kit Video Doorbell E340,4K Solar Camera Wireless Outdoor, Triple Lens Bullet-PTZ Cam, 360° View, AI Recognition, 8X Zoom, 0 Monthly Fee, Local Storage
A single groundbreaking device that replaces and outperforms separate bullet and PTZ cameras. The upper 4K bullet lens delivers a 130° fixed wide view, while the lower 2K dual-lens PTZ offers 360° smart tracking and zoom.
Once the bullet cam detects a subject, the PTZ camera instantly locks on, tracks, and zooms in to capture details up to 164 ft away. When more subjects enter the frame, it automatically zooms out to ensure they all stay visible.
Stay charged year-round with a 5.5W ultra-large solar panel and SolarPlus 2.0. Just 1 hour of direct sunlight a day keeps the camera running, and the detachable design makes setup easy and flexible.
eufyCam S4 can work independently—no HomeBase needed. It features on-device AI for smart human, vehicle, and pet detection. It comes with 32 GB built-in storage, expandable up to 256 GB via microSD (not included).
Unlock BionicMind AI to differentiate family from strangers. With 16 GB built-in storage, expandable up to 16 TB, rest easy knowing your videos are stored securely. Use the latest eufy app and update HomeBase S380 to V3.7.2.8+ to enable 24/7 recording and Snapshots. Other HomeBases (S280/Mini/Professional) and eufy NVR are not supported.
Is the video door bell rechargeable battery operated?
Yes, the Video Doorbell E340 is powered by a built-in rechargeable battery. It can also be hardwired to existing doorbell wiring for continuous power, but it operates fully wireless on battery alone if preferred.
Does thiq come with hard drive?
No, it does not come with a hard drive. The HomeBase 3 included in the kit has 16GB of built-in eMMC storage. If you need more recording capacity, you can add an external USB hard drive or SSD (up to 2TB) to the HomeBase.
What is the maximum solar power camera that you can hook up on this system?
The eufy HomeBase 3 included in this kit supports up to 16 wireless cameras total, including solar‑powered models like the eufyCam S4. The kit ships with 4 solar cameras and the Video Doorbell E340. You can add up to 16 additional solar cameras (for a theoretical maximum of 16 solar cameras in total) — or a mix of solar, battery, and wired cameras — as long as the combined total does not exceed 16 cameras. (The doorbell does not count toward the 16‑camera limit; HomeBase 3 can also handle up to 4 doorbells.)
Can I use some in remote locations and some within wifi range
You can use it as long as there is Wi-Fi.
