About the Vivotek FE9391-EHV
The Vivotek FE9391-EHV is a discreet dome housing well-suited to indoor retail, office, lobby, and educational environments where aesthetics matter. 4K (8MP) resolution roughly quadruples 1080p pixel density, pushing usable identification distance past 25 meters and giving forensic-grade digital zoom on archived footage. 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.
Best use cases for this camera
Entrance, lobby & vestibule
The 180° 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.
Retail & office interior
Dome form factor and 8.7MP (2944×2944) resolution make this a clean retail/office choice — the housing blends into ceilings and the sensor delivers enough detail for POS-area monitoring and incident review.
Strengths
- •8.7MP sensor preserves detail under digital zoom on recorded footage
- •180° wide field of view reduces the number of cameras needed per area
- •Vandal-resistant dome housing harder to tamper with than bullet form factor
- •30m effective range supports outdoor perimeter and parking-lot deployments
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
- •Higher resolution increases storage and bandwidth requirements proportionally — verify NVR capacity

Field of View Visualization
Night Vision Performance
Daytime
Full 8.7MP (2944×2944) resolution at 180° field of view. Effective identification range up to 30m in good lighting conditions.
Nighttime (IR)
Built-in IR LEDs illuminate up to 20m in complete darkness. Switches to B/W mode for clear night footage.
Installation tips for the FE9391-EHV
Ceiling-mount at 2.5–3.5 m for indoor use; for vandal-prone outdoor locations use a wall mount with the lens facing outward and downward.
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.
Plan storage at roughly 35 GB per camera per day for continuous H.265 recording at 15fps — verify NVR has sufficient HDD bay capacity.
Coverage geometry & DORI distances
At a 5-metre standoff the Vivotek FE9391-EHV covers about 163312393531953696.0 m of scene width; at 10 m that grows to 326624787063907392.0 m, and at 20 m to 653249574127814784.0 m. Translating those numbers through EN 62676-4 pixel-density thresholds, the camera can detect a person up to 0 m, observe up to 0 m, recognise up to 0 m, and produce identification-grade detail (the ≥250 px/m bar used by Polish and EU courts as evidentiary) up to 0 m. Effective range above the identify threshold relies on supplementary lighting or a longer-focal-length optic — the geometry above assumes the 1.22mm lens declared by the manufacturer.
Power & cabling
The Vivotek FE9391-EHV 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. With 180° horizontal FOV and 30 m effective range, a single dome camera unit covers a large swath of scene — confirm during commissioning that no part of the visible area extends beyond the property boundary, and add a privacy mask if it does.
Installer time & cost (rough estimate)
A typical EU installer quotes 3–4 h of labour per dome 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 Vivotek FE9391-EHV suitable for outdoor installation?
Yes for the IP66/IP67-rated variant of this model. Bullet and dome bodies in the Vivotek 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 Vivotek FE9391-EHV?
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 Vivotek FE9391-EHV consume per day?
At 8.7MP (2944×2944) resolution, 15 fps H.265 continuous recording, the FE9391-EHV produces approximately 35 GB per day — about 1050 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 Vivotek FE9391-EHV identify a person?
Per EN 62676-4:2025 pixel-density thresholds, this camera identifies (≥ 250 px/m on the target) up to about 0 m, recognises a person up to 0 m, observes general activity up to 0 m, and detects motion up to 0 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 Vivotek FE9391-EHV use?
Typical ingest is 13 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.
