The Eufy PoE Bullet Security Camera E40 is aimed at homeowners and small business owners who want the reliability of wired infrastructure, along with local storage of security camera recordings to eliminate the cost of a cloud subscription. It’s built for people who take their security seriously and are willing to pull cables through their walls to get it. The camera must be paired with Eufy’s PoE NVR, which you’ll likewise need to hardwire to your home network.

For those unfamiliar with the terms, PoE stands for Power-over-Ethernet (both power and data travel over a single ethernet cable, eliminating the need for an outdoor power outlet), and NVR stands for Network Video Recorder (it’s a similar concept to the DVR–digital video recorder–you might connected to your TV). I evaluated the camera with the Eufy Network Video Recorder S4 I reviewed in July 2025.

Specifications

The E40 is a classic bullet-style security cameras built for the outdoors. It has a metal housing and a weatherization rating of IP67, meaning it’s dustproof and can withstand immersion in up to one meter (about 3.3 feet) of water for up to 30 minutes.

Inside that housing is a 4K single-lens camera with a wide 122-degree field of view. It supports up to 5x digital zoom, letting you focus in on details while reviewing footage. The E40 offers three modes for nighttime coverage: starlight color night vision for low-light scenes, a spotlight-enhanced mode for complete darkness, and a traditional black-and-white infrared mode when you prefer to keep things discreet.

The camera’s on-device AI can distinguish between people, pets, and vehicles, reducing false alarms from passing cars or wandering wildlife. You can further minimize unwanted notifications by setting activity zones and schedules, so it only alerts you when and where you want.

For active deterrence, the E40 is equipped with a built-in siren and flashing red and blue lights that mimic police strobes. Two-way audio with noise reduction can also be used to can warn off intruders or speak with visitors. The camera system can be integrated with Amazon Alexa or Google Home, but there’s currently no support for Apple Home.

Setup and performance

Installing the PoE Cam E40 is straightforward, provided you’re comfortable pulling ethernet cable from the camera back to Eufy’s NVR. The included mounting hardware gives you flexibility in positioning the camera, whether you’re attaching it to a wall, under an eave, or on a pole.

The Eufy Network Video Recorder S4 comes with 2TB of storage via a mechanical hard drive, and it can be expanded up to 16TB by replacing the factory-installed drive in its single 3.5-inch bay. You’ll likely need more capacity if you elect for 24/7 recording.

Setting up the NVR is more involved than a wireless camera install. You’ll need to hardwire it to your router, plug in the included mouse for system control, and hook up a monitor to its HDMI port. It’s then it’s a matter of choosing your camera locations, mounting the brackets, attaching the cameras, and drilling holes in your walls to feed ethernet cables through the provided weatherproof grommets. Once everything’s connected to the NVR, the hard part is over; the system automatically detects the cameras and you can access the system via the monitor, the Eufy app, or Eufy’s web portal.

Video quality in daylight is excellent, with 4K resolution delivering sharp detail and accurate color. At night, the starlight sensor produces a clear, colorful image in low-light conditions. When the scene is completely dark, the spotlight mode kicks in to illuminate and capture maximum detail. Infrared mode provides ample light to capture clear black-and-white footage.

Eufy’s onboard AI does a solid job of recognizing people, vehicles, and pets, and custom activity zones help reduce false alarms triggered by irrelevant movement. Alerts arrive promptly, and the classification accuracy keeps notifications useful rather than overwhelming. If you’re running multiple cameras, as you most likely will be, you can choose to default to the NVR’s global AI settings, which will override individual camera settings. This makes it easier to apply consistent detection rules across your system without having to configure each camera separately.

When deterrence is needed, the flashing red and blue lights demand attention, and the two-way audio is loud and clear enough to startle someone who shouldn’t be there.

The Eufy Security app ties it all together. You’ll use it to view live feeds, scrub through recordings, and manage your video, audio, and notification settings. Streaming over a local network is smooth, and the app gives you direct control over how the camera behaves day to day.

Should you buy the Eufy PoE Cam E40?

At $130, the Eufy PoE Cam E40 delivers a lot for its price. You get sharp 4K video, reliable AI detection, and built-in deterrence features—all without the ongoing cost of a cloud subscription. Be sure to factor in the cost of the 8-channel (expandable to 16 channels) Eufy Network Video Recorder S4 ($400), because the camera can’t operate without it. If you’re starting from scratch, Eufy also offers the NVR bundled with four E40 cameras for $800, a $119 discount if you’re planning full-home coverage. Eufy offers bundles with combinations of cameras (e.g., you can buy the Eufy NVR with two bullet cameras and two pan/tilt cams for $1,000).

You will need to accept some trade-offs. The PoE requirements mean you might need to do a fair amount of drilling and routing if your home isn’t already set up for it. And if you’re in the Apple Home ecosystem, this camera won’t slot into your setup.

If you can work within those limits, the Eufy PoE Cam E40 and Eufy Network Video Recorder S4 are a smart buy. The system is built for long-term use, and it provides the kind of always-on security that’s hard to get from battery-powered, wireless alternatives.
