eufy NVR Wi-Fi Module Guide: Buy It Alone or in a Bundle?

eufy is best known for home security cameras that store video locally instead of sending everything to a paid cloud service. Its newer PoE NVR systems take that idea further: PoE (Power over Ethernet) cameras get power and data through a single network cable, and the NVR (network video recorder) is the box with a hard drive that records all those cameras in one place. The eufy NVR Wi-Fi module is a small add-on that lets that wired recorder also talk to eufy’s battery-powered Wi-Fi cameras and sensors.
The six items here differ in what comes in the box: the Wi-Fi module on its own, the module bundled with an S4 Max system, three bundles pairing the module with an NVR S4 and one camera (the E40 bullet, E41 bullet or Bullet-PTZ S4), and a driver module for eufy’s outdoor lights that is not part of the NVR system at all.

eufy NVR Wi-Fi Module for Existing PoE NVR Owners
The eufy NVR Wi-Fi Module is the stand-alone part, and the listing is clear that it works only with a eufy PoE NVR system. Plug it in and your NVR can manage and record up to 16 eufy Wi-Fi cameras and 32 eufy sensors alongside its wired cameras. Those Wi-Fi cameras then gain NVR features such as smart video search, built-in local storage, enhanced AI recognition and app or web control.
If you already use a HomeBase 3 or HomeBase 2 (eufy’s earlier hubs for battery cameras), one-click migration lets you move cameras to the NVR in the eufy Security app without re-pairing or resetting them. The module is dual-band, supports WPA-PSK and WPA2-PSK security, uses Wi-Fi and Sub-1GHz radio, and lists a 130 Mbps data rate. Before pairing, wait a few minutes for updates until the status light turns solid blue, and make sure the NVR firmware is V1.3.1.8 or above and the app is V6.0.00 or above.
Buy it alone if you already own the recorder and wired cameras. If you are starting from nothing, a bundle below saves you buying pieces separately. Our overview of the eufy NVR system explains the recorders in more depth.

- Pre-installed 2 TB drive
- Triple-lens Bullet-PTZ camera
- Live cross-cam tracking
Cons
- PoE switch for 16 channels extra
- Camera count not clearly listed
This eufy Wi-Fi Module listing bundles the module with the eufy 4K NVR Security Camera System S4 Max. The listing describes an 8-port NVR that can expand to 16 channels with a PoE switch (sold separately), a pre-installed 2 TB hard drive upgradeable to 16 TB for 24/7 recording, and a 4K triple-lens Bullet-PTZ camera. That camera pairs a 4K wide-angle lens with a 122° fixed view and a 2K PTZ lens (pan, tilt, zoom) with 8x auto-zoom and 360° pan.
Live cross-cam tracking lets cameras hand off a moving subject to each other. The NVR supports up to 8 Bullet-PTZ cams (each uses 2 channels) or up to 16 bullet or turret cams. The listing states a unit count of 2 but does not specify how many cameras are in the box, so check the product page’s “what’s included” before ordering.
Choose this bundle if you want the largest listed system with room to grow. For a smaller start, the NVR S4 bundles below each pair the module with one camera. Shoppers comparing multi-camera systems more broadly may also like our wired camera system guide.
eufy Wi-Fi Module & PoE Bullet E40 Bundle for a Simple Start
The eufy Wi-Fi Module & PoE Bullet Security Camera E40 bundle includes the module, the E40 camera and the Network Video Recorder S4, three items in all. The E40 records 4K Ultra HD with a 122° field of view. The listing notes the E40 requires the NVR S4 to operate, which is why the recorder is included.
Starlight color night vision uses AI-ISP image processing to show color at night without a spotlight; switch the spotlight on for more clarity, and HDR keeps bright areas from washing out, enough to read a license plate. AI detection tells people, pets and vehicles apart, which eufy says cuts false alerts by 99%. A local AI agent with 6T/8-core processing lets you set no-go zones and custom alerts.
This is a straightforward starter kit for one entrance or driveway, with the module ready for Wi-Fi cameras later.
eufy Wi-Fi Module & PoE Bullet E41 Bundle for an Alternate Bullet Camera
This eufy Wi-Fi Module & PoE Bullet Security Camera E41 bundle also includes three items: the module, the E41 camera and the NVR S4. The listed features match the E40 bundle word for word: 4K, 122°, starlight color night vision, spotlight, HDR, AI human, pet and vehicle detection and the local AI agent. The E41 also needs the NVR S4 to run.
The listing does not specify what separates the E41 from the E40, such as housing, color or mounting. If the difference matters, compare photos on each product page or ask eufy directly.
Pick whichever of the E40 or E41 bundles is in stock or suits your look, since the listed features are the same.
eufy Wi-Fi Module & PoE Bullet-PTZ Cam S4 Bundle for Tracking Wide Areas
The eufy Wi-Fi Module & PoE Bullet-PTZ Cam S4 bundle pairs the module and NVR S4 with the most capable camera here. The upper 4K lens covers a 122° view while the lower 2K PTZ lens has 8x auto-zoom and 360° pan. When the wide camera spots someone, the PTZ lens locks on and follows them in centered close-ups from up to 164 ft away, with group tracking for more than one subject.
It includes starlight color night vision and the local AI agent, and the spec list names 16 channels, an Ethernet interface and a digital IP video input. The camera requires the NVR S4. The listing does not specify the hard drive size in this bundle.
Choose it for a long driveway, a yard or a small business lot where zoom and tracking matter. For a single doorway, a bullet bundle is simpler.
eufy Driver Module for 200 ft for Permanent Outdoor Lights S4
Best for: Permanent Outdoor Lights S4 runs past 150 ft
Pros
- Supports runs up to 200 ft
- Keeps brightness steady over distance
Cons
- Not a camera or Wi-Fi part
- No power supply or control box
The eufy Driver Module for 200 ft (model T8C01) often appears next to the NVR module in searches, but it is a lighting accessory. It is a voltage booster for eufy Permanent Outdoor Lights S4 that keeps brightness consistent when you extend a strip to 200 ft (60 m); eufy says it raises brightness by 25% when extending 150 ft lights to 200 ft.
It does not include a power adapter, plug, cord, extension cord or control box, and it has no control functions. If your light run is 150 ft (45 m) or less, you do not need it. It requires app version 5.7.0 or above and light firmware 3.0.7.5 or above. It is white ABS and weighs 9.9 ounces.
Buy it only if you own those lights and are extending past 150 ft.
How to Choose the Right eufy NVR Wi-Fi Module or Bundle

Mixing in battery cameras. Any of the module options let the NVR handle up to 16 Wi-Fi cameras and 32 sensors. For indoor coverage ideas, see our indoor camera guide.
