Eufy NVR Security System S4 Max

Customers love this because it tracks people and vehicles automatically across your property whilst the keyword search means you find the moment you need without hours of scrolling. The straightforward PoE setup gets it running in minutes, and you can expand from 8 to 16 cameras as your security needs grow.

Overview

Manufacturer Guarantee	3 Years

The eufy NVR Security System S4 Max delivers professional-grade security with four 16MP triple-lens cameras that provide 360° coverage. Its standout feature is the dual bullet and PTZ (Pan-Tilt-Zoom) design, where the upper 4K camera offers a fixed 122° wide view whilst the lower 2K PTZ lenses zoom in up to 8× and pan 360°. The system automatically tracks movement across multiple cameras in real-time, keeping subjects centred in frame from up to 50 metres away.

Installation is straightforward with PoE (Power over Ethernet) connectivity—each camera connects to the Network Video Recorder using a single cable. The NVR comes with a 2TB hard drive (upgradeable to 16TB) and supports up to 8 cameras initially, expandable to 16 with a PoE switch. An on-device AI agent processes video locally for instant threat detection without relying solely on cloud analysis.

More Details

Complete 360° Security Coverage

The four 16MP triple-lens cameras work together to eliminate blind spots around your property. The fixed 4K bullet camera delivers a 122° wide-angle view across the main area, whilst the dual 2K PTZ cameras rotate a full 360° and zoom in to capture fine details. This combination ensures you see everything from wide overviews to close-up identification.

Intelligent Tracking That Follows the Action

When motion is detected, the system’s dynamic tracking engine automatically locks the PTZ cameras onto the subject. The auto-framing feature keeps people or vehicles centred in the shot as they move, with sharp focus maintained from up to 50 metres away. Live cross-camera tracking means when one camera reaches its pan limit, the next camera seamlessly takes over, providing continuous coverage without gaps.

Three Night Vision Modes for Round-the-Clock Monitoring

The system includes Starlight mode for low-light colour vision, Spotlight mode for enhanced brightness, and infrared mode for complete darkness. This flexible approach lets you choose the right balance between detail and power consumption depending on conditions.

AI-Powered Search and Local Processing

Rather than manually scrolling through hours of footage, use the AI-powered video finder to search by keywords such as ‘person’, ‘car’, or ‘pet’ directly in the eufy app. An 8-core on-device AI agent analyses video locally in real-time, identifying genuine threats like strangers from legitimate visitors. You can customise no-go zones and set intelligent alerts that react only to specific threats.

Simple Setup and Future-Proof Expansion

Each camera connects to the NVR with just one PoE cable—no separate power adapters required. Out of the box, the system manages 8 cameras. As your security needs grow, add a PoE switch to expand up to 16 cameras without replacing the core system. The 2TB hard drive handles continuous 24/7 recording and is upgradeable to 16TB for extended storage.

Built for Any Weather

IP65 weatherproofing ensures cameras operate reliably in rain, snow, and harsh sunlight. The built-in wind dome reduces audio interference from wind, and dual-view capability lets you monitor the main area and zoomed details simultaneously.

Questions & Answers

: The system uses live cross-camera AI tracking, where all cameras work in sync. When one camera detects motion, it locks on and tracks the subject. When that camera reaches its pan limit, the next camera automatically takes over, ensuring continuous tracking without interruption.
: The PTZ cameras feature 8× hybrid zoom (with 3× optical zoom) and can track subjects from up to 50 metres away. The auto-framing feature keeps subjects centred in frame as they move.
: Yes. The AI-powered video finder lets you search by keywords like 'person', 'car', 'pet', or 'stranger' directly in the eufy app, so you don't need to scroll through hours of video to find what you're looking for.
: The NVR supports 8 cameras out of the box and can be expanded to 16 channels with a PoE switch. The 2TB hard drive is upgradeable up to 16TB for extended storage.
: The system includes an on-device AI agent with an 8-core CPU that performs threat detection and analysis locally. However, if you choose to use cloud-based features such as cloud storage or push notifications with thumbnail previews, those will be sent to the cloud as needed.
