Triple-Lens 16 MP Camera System

The eufy S4 Max combines a 4K wide-angle lens with a 2K PTZ lens that delivers 8× auto-zoom and 360° pan. Cross-cam tracking hands off subjects between cameras for continuous coverage. A pre-installed 2 TB drive supports 24/7 recording and can be upgraded to 16 TB.

Expandable PoE Security for Home or Business

Suits owners who want wired, weatherproof IP65 cameras with local AI detection and smart video search via the eufy app version 5.0.71 or later. Not for buyers who need wireless battery cameras, cloud-only storage, or more than 16 channels of real-time video.

Dual-Stream Bullet-PTZ Uses Two Channels

Each Bullet-PTZ camera occupies two of the NVR's 16 real-time streams, so a maximum of eight such cameras can be connected. The single 3.5-inch bay holds the included 2 TB HDD and accepts upgrades up to 16 TB.

Questions about this item

What comes in the box and what must be purchased separately to reach 16 channels?

The system includes one 16 MP triple-lens Bullet-PTZ camera, an 8-channel NVR with a pre-installed 2 TB hard drive, and a single PoE cable for power and video. Additional cameras up to eight Bullet-PTZ units are sold separately to reach the 16-channel maximum.

How do I choose between the 8-channel starting point and the 16-channel maximum?

The NVR ships ready for eight channels and can be expanded to 16 by adding more Bullet-PTZ cameras. Each Bullet-PTZ uses two real-time streams, so eight such cameras fill the 16-channel limit.

What does the 164 ft auto-zoom range mean when the camera is mounted on my property?

When the wide-angle bullet lens detects a subject, the PTZ lens locks on and keeps the person or vehicle framed in close-up up to 164 ft away, maintaining sharp detail until the subject leaves the field of view.
