What’s the difference between this bullet-ptz camera and using two separate cameras?

The two built-in cameras work together more intelligently than separate devices, providing both a full view and a detailed close-up from a single installation. Auto-tracking begins with either camera, then PTZ zooms in and follows the action.

How does bullet-to-PTZ tracking work?

The fixed camera detects motion and triggers the PTZ to rotate and zoom using AI tracking. If the bullet and PTZ angles differ, tracking handoff may be slower. For faster response, point the PTZ toward your key area for quicker detection.

Does eufyCam S4 support 24/7 recording?

Yes, connect it to direct power (5V/2A+ adapter or higher) for 24/7 recording (requires camera version V1.0.5.4+). A microSD card or hard drive is required for storage (when connected to HomeBase 3, requires HomeBase version V3.7.2.8 or later).

How do I get the best performance from my solar panel?

Orientation and tilt angle are key. Face the panel toward the equator (e.g., south in the Northern Hemisphere), place it in a shadow-free spot, and set a 30°–45° tilt based on your latitude—flatter in summer, steeper in winter for maximum charging.

Can it work standalone or with other Hombases / HomeKit?

It works as a standalone device (connected directly to your router) or with HomeBase S380 for more features.

HomeBase 2(Homebase S280) , Homebase mini, Homebase Professional, eufy NVR and Apple HomeKit are not currently supported.

Total Property Coverage with Revolutionary 2-In-1 Design: Secure every corner of your property with zero blind spots. In this 4-camera bundle, every single device does the work of two. The innovative Triple-Lens system combines an upper 4K bullet lens (130° wide view) with a lower 2K PTZ lens that locks on, tracks, and zooms. Get both the complete scene and crucial close-ups at the same time. It’s the perfect all-in-one security solution for large estates, sheds, rental.
AI Tracking from Close-Ups to Cross-Zones: Each camera independently utilizes AI to lock on, auto-frame multiple subjects, and zoom in for crisp details up to 164 ft away. Linked by the HomeBase S380, the 4-camera bundle takes it further with true Cross-Camera Tracking. As someone walks through your property, the cameras hand off the target seamlessly, stitching the activity across different zones into one continuous, timestamped video.
Forever Solar Power & Effortless Setup: Skip the hardwiring and professional installers! Equipped with an ultra-large 5.5W solar panel and SolarPlus 2.0 tech, just 1 hour of direct sunlight daily keeps your camera running year-round. Thanks to this 100% wire-free, smart detachable design, you can easily mount and set up the camera anywhere in just minutes.
No Subscription & Guaranteed Privacy with HomeBase S380: This bundle securely stores all your footage locally on the HomeBase S380’s 16GB built-in drive (expandable with any 2.5″ drive). Beyond massive storage, the hub unifies all 4 cameras into one easy-to-use app. Featuring local BionicMind AI, it learns to recognize familiar faces, drastically reducing false alerts so you’re only bothered by real threats. Starting with 4 cameras, this highly scalable system can easily support up to 16 devices total.
Precise Detection, Powerful Deterrence: Radar and PIR sensors deliver precise motion alerts with fewer false alarms. When a threat is detected within your set zone or schedule, red and blue warning lights and a 105 dB siren activate to deter intruders.
