About the Eufy SoloCam S40
The Eufy SoloCam S40 is a rugged outdoor-grade bullet form factor designed to withstand exposure to weather, vandalism, and direct sunlight. 4MP resolution delivers a noticeable detail upgrade over 1080p — facial identification extends to roughly 18 meters, and digital zoom on recorded footage stays usable. A short-range IR illuminator (≤20 m) handles entrance vestibules, indoor corridors, and small enclosed spaces. Beyond 20 meters the IR fall-off causes faces to lose detail in pure darkness. An ultra-wide angle (>120°) captures nearly an entire scene from one position, but pixels per meter drops sharply at the edges, so identification at the periphery is limited. Super Low Light technology pulls usable color out of scenes lit by little more than a streetlight or moonlight, eliminating the need to drop into B/W mode in most night conditions.
Best use cases for this camera
Entrance, lobby & vestibule
The 122° field of view captures the entire entrance and surrounding waiting area from a single ceiling mount. Useful for capturing visitors as they enter and leave.
Strengths
- •Super Low Light sensor maintains color detail in near-darkness
- •122° wide field of view reduces the number of cameras needed per area
Considerations
- •Short IR range limits night usability to indoor or close-proximity scenarios
- •Edge distortion and reduced peripheral pixel density limit identification at the corners of the frame

Field of View Visualization
Night Vision Performance
Daytime
Full 3.7MP (2560×1440) resolution at 122° field of view. Effective identification range up to 20m in good lighting conditions.
Nighttime (IR)
Built-in IR LEDs illuminate up to 8m in complete darkness. Super Low Light sensor captures colour images in near-darkness.
Installation tips for the SoloCam S40
Pair with low-cost ambient lighting (motion-triggered LED floods) to extend usable identification distance beyond the IR limit.
Position so the most important subject (entrance, cash register, gate) is in the center third of the frame — peripheral pixel density drops with wide angles.
Coverage geometry & DORI distances
At a 5-metre standoff the Eufy SoloCam S40 covers about 18.0 m of scene width; at 10 m that grows to 36.1 m, and at 20 m to 72.2 m. Translating those numbers through EN 62676-4 pixel-density thresholds, the camera can detect a person up to 28 m, observe up to 11 m, recognise up to 6 m, and produce identification-grade detail (the ≥250 px/m bar used by Polish and EU courts as evidentiary) up to 3 m. Effective range above the identify threshold relies on supplementary lighting or a longer-focal-length optic — the geometry above assumes the fixed lens declared by the manufacturer.
Power & cabling
The Eufy SoloCam S40 draws an estimated 7.5 W under typical load (with the IR illuminator engaged where applicable), placing it in the 802.3af (Class 3, ≤15.4 W) budget. A single switch port supplies enough power without an injector. Cabling: stick to Cat6 STP for runs up to 100 m end-to-end — beyond that, add an inline PoE extender or move to fibre with a media converter at the camera end. On outdoor runs, route through ø25 PVC or PE conduit to keep the cable shielded from UV and rodents.
Privacy & legal (GDPR / RODO)
Any camera operating in a publicly accessible area falls under GDPR (RODO in Poland) — Art. 13 obliges the data controller to post an information sign at every entry point with controller name, DPO contact, lawful basis (typically Art. 6(1)(f) legitimate interest for property protection), purpose, and retention period. Even a narrowly-aimed bullet camera can incidentally record passers-by, so the Art. 13 sign at the entry point applies regardless of how tightly the lens is framed.
Installer time & cost (rough estimate)
A typical EU installer quotes 3–4 h of labour per bullet camera of this class (approximately €135–€185 excluding hardware), broken down as bracket mounting, cable termination at both ends, on-site commissioning, and a brief operator handover. Allow extra time for high mounts (>4 m), exterior installations requiring scaffolding, or sites where cable routing demands wall penetrations or conduit work.
Indicative EU 2024-2025 pricing — actual quotes vary by region, mounting height, and site conditions. Excludes hardware, transport, permits, and VAT.
Frequently asked questions
Is the Eufy SoloCam S40 suitable for outdoor installation?
Yes for the IP66/IP67-rated variant of this model. Bullet and dome bodies in the Eufy range survive direct rain, snow and UV; check the IP / IK rating against your environment (IP66 for rain/dust, IK10 for vandal-prone locations).
What PoE class powers the Eufy SoloCam S40?
The camera draws roughly 7.5 W in steady-state operation, requiring a 802.3af (Class 3, ≤15.4 W) switch port. A single Cat6 STP cable carries both data and power up to 100 m — beyond that, add an inline extender or convert to fibre near the camera.
How much storage does the Eufy SoloCam S40 consume per day?
At 3.7MP (2560×1440) resolution, 15 fps H.265 continuous recording, the SoloCam S40 produces approximately 15 GB per day — about 450 GB per month. Motion-only or event-triggered recording typically cuts that by 40–70 % depending on scene activity. Plan NVR HDD capacity for the longest retention period required by your privacy policy or insurance contract.
Up to what distance can the Eufy SoloCam S40 identify a person?
Per EN 62676-4:2025 pixel-density thresholds, this camera identifies (≥ 250 px/m on the target) up to about 3 m, recognises a person up to 6 m, observes general activity up to 11 m, and detects motion up to 28 m. Identification distance assumes daylight or full IR illumination on the target — at the limits of the IR cone the effective identify distance shrinks roughly 30 %.
What network bandwidth does Eufy SoloCam S40 use?
Typical ingest is 6 Mbps for the main stream (H.265, medium scene complexity, 15 fps) plus ~0.5 Mbps for a low-resolution sub-stream used by mobile clients. For a 16-camera installation of this class, plan a 50–100 Mbps NVR uplink and a dedicated VLAN for camera traffic.
