Why choose the Eufy S4 system?

This system offers the best of both worlds: 2 discreet 4K turret cameras for unobtrusive permanent monitoring of critical zones and 2 intelligent bullet-PTZ cameras that automatically zoom in and track moving objects.

The compact turret cameras are subtle and discreet—perfect for locations where you want effective security without noticeable cameras. The bullet-PTZ cameras provide intelligent tracking: when a turret camera detects movement, the PTZ camera automatically focuses on the subject and follows it in centered close-ups up to 50 meters away. The 2K PTZ lens with 8× hybrid zoom and 360° pan/tilt misses no detail.

Cross-camera tracking:

All cameras work synchronously in real time. When a subject leaves the range of one camera, another camera automatically takes over. This ensures seamless continuous tracking without blind spots—ideal for large grounds, parking lots, or complex environments.

EdgeAICore™ local AI agent:

The powerful 6T/8-core processor in the NVR analyzes footage locally in real time. Set forbidden zones and decide per zone how the system should respond upon detection: sirens, red/blue lights, alerts, or combinations. The AI detects real threats and prevents false alarms.

Free smart video search function:

Search recordings using natural language. Type "person with backpack" or "black car" and the AI immediately finds the relevant footage. No hours of scrolling—find what you seek in seconds.

Color night vision with AI-ISP:

Thanks to AI-ISP processing and built-in spotlights, the cameras deliver bright color images at night. See details such as clothing color, vehicle type, and faces in color instead of dull black and white.

Complete PoE solution:

The system includes an NVR with 8 PoE ports and 2TB hard drive (expandable to 16TB). Connect each camera with one ethernet cable for both power and data—4x 18 meter cables are included. Plug & play installation. Expand to 16 channels by adding extra cameras and a PoE switch.

24/7 continuous recording:

The 2TB hard drive offers space for weeks of 24/7 recording of all 4 cameras. Expand to 16TB for months of storage capacity. All footage remains stored locally for maximum privacy.

Turret + PTZ combination:

This unique combination offers discreet fixed monitoring (turret) with intelligent tracking (PTZ). Perfect for locations where you want unobtrusive cameras for fixed zones combined with active tracking of moving objects.

Suitable for:

Shops, offices, business premises where discreet cameras are desired, locations with multiple entrances, parking lots, warehouses, complex environments where both discreet fixed monitoring and tracking are needed, professional 24/7 surveillance without cloud fees.
