DAHUA DH-IPC-HFW3841E-S-S2 (8 MP/2.8 MM) - PoE IP CAMERA
Description Dahua HFW3841E-S-S2
8 MP in a compact metal housing
HFW3841E-S-S2 combines a high 8 MP resolution with relatively compact dimensions (66×70×193 mm) and a fully metal housing. It's built for spots where image clarity matters within a limited mounting space, and extra recognition analytics genuinely aren't needed.
Where this camera is actually used
An IP67 rating and an operating range of -40°C to +60°C make this model suited to an outdoor perimeter, a fence, a driveway — spots where 8 MP detail matters for confident identification, not just recording that motion happened.
What problem this camera actually solves
Entry-level 2–4 MP cameras often don't deliver enough detail for confident identification of a face or license plate at real observation distances. HFW3841E-S-S2 solves this with double or triple the resolution of such models, while keeping a compact housing and simple, predictable capture without smart classification.
Home Assistant integration
Unlike a typical entry-level camera, this model supports direct integration with Home Assistant, the open-source smart home platform. That lets you fold the camera into home automation routines even without the manufacturer's own ecosystem.
PoE, ONVIF, and a local archive
PoE 802.3af power (3.5 W) means low power draw and a single cable to the camera. MicroSD support up to 256 GB and ONVIF protocol support allow a local archive and connecting the camera to third-party software or an NVR.
A practical example of Home Assistant automation
Through Home Assistant, you could, for instance, set up outdoor lights to switch on automatically when the camera's motion sensor triggers, or log the event in a shared smart-home journal alongside signals from other devices — with no tie to the camera manufacturer's own cloud service.
Why the compact size matters
At 66×70×193 mm, dimensions are noticeably smaller than typical 8 MP cameras, simplifying installation in tight spots — under a narrow eave, in a facade niche, anywhere a bulkier housing simply wouldn't fit or would look out of place.
Low power draw as an added bonus
A draw of just 3.5 W is noticeably lower than the typical 5-7 W for cameras of this class, reducing load on a PoE switch and allowing more cameras per device without upgrading network infrastructure.
MicroSD support for a local archive
Despite its compact size, the camera supports a memory card up to 256 GB right in its own housing — enough for several weeks of continuous recording depending on quality and frame rate settings.
Rated for both indoor and outdoor mounting
The manufacturer explicitly confirms compatibility with both indoor and outdoor placement — removing the need to pick a separate model if the camera later moves outside or vice versa.
Who this model is for
HFW3841E-S-S2 is the pick for an owner who needs 8 MP-level detail in a compact housing, without paying extra for smart analytics, and with the option to integrate into a Home Assistant-based smart home.
We can advise whether this model is enough for your mounting spot, or whether a version with person and vehicle recognition is worth considering.
