NVR Security Recorder Eufy E40 — 8-channel 4K input, 2 TB HDD (expandable to 16 TB), Black/Grey/White

Eufy NVR Security Recorder E40 is an 8-channel network video recorder designed for home and small-business surveillance. It accepts up to 4K (3840×2160) input from compatible Eufy cameras, provides a pre-installed 2 TB HDD (expandable to 16 TB) for continuous recording, and supports Power over Ethernet (PoE) for simplified single-cable installation. Built-in local AI capabilities enable on-device analysis and responsive alerts while IP67-rated durability ensures reliable outdoor use.

Advantages

The recorder delivers 4K UHD input and a 122° wide-angle field of view when paired with compatible cameras, producing sharp, detailed footage. Starlight color night vision with AI-ISP processing provides color detail at night without the need for constant spotlights, while optional spotlight and HDR help avoid overexposure for clearer identification. A local AI agent running on a multi-core processor enables real-time threat detection, customizable no-go zones, and instant actions. Free smart video search helps find events quickly, and a red-and-blue strobe plus smart siren act as automated deterrents. The unit supports two-way talk with AI noise reduction and is rated IP67 for weather resistance.
