eufy PoE Bullet Security Camera E40 - 4K PoE Add-On Cam

In this review the eufy PoE Bullet Security Camera E40 is evaluated as an add-on for existing eufy PoE NVR systems, ideal for users who need extra coverage with high-resolution video. The bottom line: it is best for homeowners and small businesses that already use the eufy PoE NVR and want a straightforward, high-detail camera with reliable AI alerts. The single biggest reason to buy is its 4K UHD clarity combined with PoE simplicity, which delivers continuous, sharp footage and easy installation through a single Ethernet cable.

Key Features

• 4K UHD and 122 FOV: Delivers very sharp, lifelike video and a wide 122 degree field of view to capture more of a scene with fewer blind spots.
• Starlight Color Night Vision: Produces color detail at night using AI-ISP processing so users can see nighttime scenes without constantly running a spotlight.
• AI Human Detection: Differentiates people, pets, and vehicles to reduce false alerts and help focus notifications on important events.
• Red and Blue Strobe: Includes deterrent measures where the camera can track intruders and trigger a visible strobe and siren to discourage threats.
• 24/7 PoE Recording: Uses a single PoE cable for power and video to support continuous recording when connected to a compatible eufy PoE NVR system.
• IP67 Weatherproof: Built to withstand rain, snow, and sun for reliable outdoor operation year round.

Who It's For

This camera is aimed at existing eufy PoE NVR owners-residential users upgrading coverage and small business operators who need an extra reliable 4K camera on their existing system. It suits people who prioritize image quality, dependable AI alerts, and a plug-and-play PoE setup for 24/7 recording.

It is not for buyers who want a standalone camera or a cloud-only consumer camera, since the E40 is a PoE add-on that requires an eufy PoE NVR, switch, or injector. If you need a wireless or independently operating camera, look elsewhere.
