About the Holowits Holowits E1B-5LRV(2.7-12) AI
The Holowits Holowits E1B-5LRV(2.7-12) AI is a rugged outdoor-grade bullet form factor designed to withstand exposure to weather, vandalism, and direct sunlight. 4K (8MP) resolution roughly quadruples 1080p pixel density, pushing usable identification distance past 25 meters and giving forensic-grade digital zoom on archived footage. With long-range IR you can rely on the camera as the only night-vision source over a wide area, eliminating the cost and visual clutter of dedicated IR floods. A narrow field of view trades coverage area for pixel density at distance — the right choice when you need to read faces or plates far from the camera, e.g., long corridors, gate approaches, ANPR installations.
Best use cases for this camera
Outdoor perimeter & fenceline
With 50m IR reach and 4.7MP (2880×1620) resolution, this camera covers fences, yards, and approach roads in complete darkness. Mount on poles or eaves at 4–6 m height angled slightly downward.
Long corridor & aisle monitoring
The 32° narrow angle is intentionally tuned for corridor work — it concentrates pixel density along the length of the hallway rather than wasting resolution on the side walls. Mount at the far end facing along the corridor.
License plate / ANPR
The combination of 32° narrow angle and 4.7MP (2880×1620) resolution provides the pixel density required for ANPR at typical lane widths, especially when paired with proper lane lighting and perpendicular mounting.
Strengths
- •4.7MP sensor preserves detail under digital zoom on recorded footage
- •50m IR range eliminates the need for external night-time illuminators
- •50m effective range supports outdoor perimeter and parking-lot deployments
Considerations
- •Narrow angle requires more cameras to cover wide areas — plan camera count accordingly

Installation tips for the Holowits E1B-5LRV(2.7-12) AI
Mount at 4–6 m height angled 10–20° downward — high enough to deter tampering, low enough to preserve face detail at 35m.
Avoid mounting under direct ceiling lights or behind glass — both reflect IR back into the lens and create severe glare in the image.
Plan cabling for multiple cameras to cover wide areas — at 32° you cover roughly 6 m of width per camera at 10 m distance.
Plan storage at roughly 19 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 Holowits Holowits E1B-5LRV(2.7-12) AI covers about 2.9 m of scene width; at 10 m that grows to 5.7 m, and at 20 m to 11.5 m. Translating those numbers through EN 62676-4 pixel-density thresholds, the camera can detect a person up to 202 m, observe up to 81 m, recognise up to 40 m, and produce identification-grade detail (the ≥250 px/m bar used by Polish and EU courts as evidentiary) up to 20 m. Effective range above the identify threshold relies on supplementary lighting or a longer-focal-length optic — the geometry above assumes the 2.7-12mm lens declared by the manufacturer.
Power & cabling
The Holowits Holowits E1B-5LRV(2.7-12) AI draws an estimated 12.0 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 4–5 h of labour per bullet camera of this class (approximately €180–€230 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 Holowits Holowits E1B-5LRV(2.7-12) AI suitable for outdoor installation?
Yes for the IP66/IP67-rated variant of this model. Bullet and dome bodies in the Holowits 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 Holowits Holowits E1B-5LRV(2.7-12) AI?
The camera draws roughly 12.0 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 Holowits Holowits E1B-5LRV(2.7-12) AI consume per day?
At 4.7MP (2880×1620) resolution, 15 fps H.265 continuous recording, the Holowits E1B-5LRV(2.7-12) AI produces approximately 19 GB per day — about 570 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 Holowits Holowits E1B-5LRV(2.7-12) AI identify a person?
Per EN 62676-4:2025 pixel-density thresholds, this camera identifies (≥ 250 px/m on the target) up to about 20 m, recognises a person up to 40 m, observes general activity up to 81 m, and detects motion up to 202 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 Holowits Holowits E1B-5LRV(2.7-12) AI 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.
