About the Holowits Holowits E1B-4LRV(3.6)
The Holowits Holowits E1B-4LRV(3.6) 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. 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 standard 50–80° horizontal FOV mimics how a person sees a scene and works well for general-purpose monitoring of rooms, parking spaces, and perimeter walls without distortion. 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
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 78° field of view spans roughly 81 meters at the camera's effective range — wide enough to monitor multiple parking rows from a single mounting point.
Entrance, lobby & vestibule
Low-light sensitivity preserves face detail even when interior lighting is dimmed for energy savings. Useful for capturing visitors as they enter and leave.
Strengths
- •50m IR range eliminates the need for external night-time illuminators
- •Super Low Light sensor maintains color detail in near-darkness
- •50m effective range supports outdoor perimeter and parking-lot deployments
Considerations
- •No notable limitations for the intended class of installations

Night Vision Performance
Daytime
Full 3.7MP (2560×1440) resolution at 78° field of view. Effective identification range up to 50m in good lighting conditions.
Nighttime (IR)
Built-in IR LEDs illuminate up to 50m in complete darkness. Super Low Light sensor captures colour images in near-darkness.
Installation tips for the Holowits E1B-4LRV(3.6)
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.
Coverage geometry & DORI distances
At a 5-metre standoff the Holowits Holowits E1B-4LRV(3.6) covers about 8.1 m of scene width; at 10 m that grows to 16.2 m, and at 20 m to 32.4 m. Translating those numbers through EN 62676-4 pixel-density thresholds, the camera can detect a person up to 63 m, observe up to 25 m, recognise up to 13 m, and produce identification-grade detail (the ≥250 px/m bar used by Polish and EU courts as evidentiary) up to 6 m. Effective range above the identify threshold relies on supplementary lighting or a longer-focal-length optic — the geometry above assumes the 3.6mm lens declared by the manufacturer.
Power & cabling
The Holowits Holowits E1B-4LRV(3.6) 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-4LRV(3.6) 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(3.6)?
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(3.6) consume per day?
At 3.7MP (2560×1440) resolution, 15 fps H.265 continuous recording, the Holowits E1B-4LRV(3.6) 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(3.6) identify a person?
Per EN 62676-4:2025 pixel-density thresholds, this camera identifies (≥ 250 px/m on the target) up to about 6 m, recognises a person up to 13 m, observes general activity up to 25 m, and detects motion up to 63 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(3.6) 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.
