Vivotek IB839-EHTV-V2
Bullet Camera with 4.9MP (2560×1920) resolution, 95.4° field of view, and 40m IR night vision range.
A 2.8–12 mm motorized zoom means the IB839-EHTV-V2 can be framed for anything from a 95-degree overview to a narrow gate or loading-bay shot without changing SKUs. Refreshed as a V2 in May 2025, this 5MP VORTEX bullet pairs WDR Pro with 40 m of smart IR, and its IP67/IK10 housing suits exposed poles and low, reachable mounting heights.

About the Vivotek IB839-EHTV-V2
The Vivotek IB839-EHTV-V2 is a weather-sealed bullet housing optimized for perimeter, parking, and exterior building installations. At 5-to-6MP the sensor sits between 1080p economy and 4K forensic detail: enough pixels-per-metre for evidence-grade faces at typical entrance and driveway distances, while keeping recording bitrate materially lighter than an 8MP camera. Medium IR range (20–40 m) is appropriate for typical residential driveways, small commercial perimeters, and back-of-house loading bays where reach beyond ~30 m is rarely needed at night. A wide 80–120° angle covers a large room or open area from a single mounting position, making it ideal for retail floors, conference rooms, and small parking lots.
Best use cases for this camera
Entrance, lobby & vestibule
The 95.4° 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
- •4.9MP sensor preserves detail under digital zoom on recorded footage
- •95.4° wide field of view reduces the number of cameras needed per area
Considerations
- •No notable limitations for the intended class of installations

Night Vision Performance
Daytime
Full 4.9MP (2560×1920) resolution at 95.4° field of view. Effective identification range up to 40m in good lighting conditions.
Nighttime (IR)
Built-in IR LEDs illuminate up to 40m in complete darkness. Switches to B/W mode for clear night footage.
Installation tips for the IB839-EHTV-V2
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 20 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 IB839-EHTV-V2 covers about 11.0 m of scene width; at 10 m that grows to 22.0 m, and at 20 m to 44.0 m. Translating those numbers through EN 62676-4 pixel-density thresholds, the camera can detect a person up to 54 m, observe up to 21 m, recognise up to 11 m, and produce identification-grade detail (the ≥250 px/m bar used by Polish and EU courts as evidentiary) up to 5 m. Effective range above the identify threshold relies on supplementary lighting or a longer-focal-length optic — the geometry above assumes the 2.8-12mm lens declared by the manufacturer.
Power & cabling
The Vivotek IB839-EHTV-V2 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 Vivotek IB839-EHTV-V2 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 IB839-EHTV-V2?
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 IB839-EHTV-V2 consume per day?
At 4.9MP (2560×1920) resolution, 15 fps H.265 continuous recording, the IB839-EHTV-V2 produces approximately 20 GB per day — about 600 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 IB839-EHTV-V2 identify a person?
Per EN 62676-4:2025 pixel-density thresholds, this camera identifies (≥ 250 px/m on the target) up to about 5 m, recognises a person up to 11 m, observes general activity up to 21 m, and detects motion up to 54 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 IB839-EHTV-V2 use?
Typical ingest is 7 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.
