Key Features

High-Resolution Surveillance

Designed for sharp, detailed monitoring, the E40 captures video in 2K QHD (4 MP) resolution, ensuring clear imagery for identifying people, vehicles, and events throughout your property. A 130° field of view provides wide coverage, reducing blind spots while maintaining visual clarity.

MaxColor Vision Night Imaging

Equipped with MaxColor Vision™ technology, this camera delivers day-like color video even in low-light conditions, far surpassing traditional infrared black-and-white night modes. Color night vision enhances situational awareness and aids in accurate visual interpretation after dark.

Solar-Powered Operation

The E40 includes a built-in SolarPlus 2.0 panel and supports optional external solar panels for continuous charging, minimizing maintenance and ensuring sustained power even in low sunlight environments. This hybrid solar-battery architecture promotes long-term deployment without frequent battery swaps.

Advanced Motion Sensing

An upgraded Passive Infrared (PIR) sensor provides intelligent motion detection with minimized false triggers, differentiating between human presence and irrelevant motion sources. Alerts are delivered promptly, enabling faster response to genuine security events.

Two-Way Audio & Alarm Integration

The built-in full-duplex two-way audio system includes noise cancellation for clear communication with visitors or delivery personnel. Additionally, the camera supports an optional 150-lumen spotlight and 105 dB siren to deter suspicious activity, combining visual and audible deterrence.

Seamless Smart Home Connectivity

This camera interoperates with major smart platforms such as Amazon Alexa and Google Assistant, allowing voice-assisted control and integration into broader automation routines. Local management remains within the Eufy Security app for configuration, alerting, and live view.

Weatherproof & Durable Design

Built for outdoor deployment, the E40’s IP66 weatherproof rating ensures resistance to rain, dust, and environmental stressors, delivering reliable performance across seasons and climates.
