About the Holowits Holowits E1B-4LRV(2.8)
The Holowits Holowits E1B-4LRV(2.8) is a long-distance bullet body that mounts cleanly under eaves, on poles, or along fencelines. 4MP sits in the sweet spot for installations where storage is a concern but you still want crisper retroactive zooming during incident review. A 50–80 m IR range turns this into a true night-perimeter camera — open yards, fenced lots, and rural properties become practical use cases without supplemental lighting. 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
Outdoor perimeter & fenceline
With 50m IR reach and 3.7MP (2560×1440) 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.
Parking lot & open yard
The 110° field of view spans roughly 143 meters at the camera's effective range — wide enough to monitor multiple parking rows from a single mounting point.
Entrance, lobby & vestibule
The 110° 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
- •50m IR range eliminates the need for external night-time illuminators
- •110° wide field of view reduces the number of cameras needed per area
- •50m effective range supports outdoor perimeter and parking-lot deployments
Considerations
- •No notable limitations for the intended class of installations

Installation tips for the Holowits E1B-4LRV(2.8)
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.
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 Holowits Holowits E1B-4LRV(2.8) covers about 14.3 m of scene width; at 10 m that grows to 28.6 m, and at 20 m to 57.1 m. Translating those numbers through EN 62676-4 pixel-density thresholds, the camera can detect a person up to 36 m, observe up to 14 m, recognise up to 7 m, and produce identification-grade detail (the ≥250 px/m bar used by Polish and EU courts as evidentiary) up to 4 m. Effective range above the identify threshold relies on supplementary lighting or a longer-focal-length optic — the geometry above assumes the 2.8mm lens declared by the manufacturer.
Power & cabling
The Holowits Holowits E1B-4LRV(2.8) 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. With 110° horizontal FOV and 50 m effective range, a single bullet 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 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-4LRV(2.8) 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-4LRV(2.8)?
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-4LRV(2.8) consume per day?
At 3.7MP (2560×1440) resolution, 15 fps H.265 continuous recording, the Holowits E1B-4LRV(2.8) 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 Holowits Holowits E1B-4LRV(2.8) identify a person?
Per EN 62676-4:2025 pixel-density thresholds, this camera identifies (≥ 250 px/m on the target) up to about 4 m, recognises a person up to 7 m, observes general activity up to 14 m, and detects motion up to 36 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-4LRV(2.8) 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.
