Specifications
About the Dahua IPC-HFW2549S-S-IL
The Dahua IPC-HFW2549S-S-IL is a weather-sealed bullet housing optimized for perimeter, parking, and exterior building installations. At 8MP the camera covers more area per device while preserving enough pixels-per-meter for legal evidence quality at typical installation distances. 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. The Super Low Light sensor is the feature most installers care about for residential and parking-lot use — it preserves identification detail when older cameras lose all color and most contour.
Best use cases for this camera
Entrance, lobby & vestibule
The 111° 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
- •Super Low Light sensor maintains color detail in near-darkness
- •111° wide field of view reduces the number of cameras needed per area
- •30m effective range supports outdoor perimeter and parking-lot deployments
Considerations
- •No notable limitations for the intended class of installations

Field of View Visualization
Night Vision Performance
Daytime
Full 4.9MP (2960×1668) resolution at 111° field of view. Effective identification range up to 30m in good lighting conditions.
Nighttime (IR)
Built-in IR LEDs illuminate up to 30m in complete darkness. Super Low Light sensor captures color images in near-darkness (down to 0.001 lux).
Installation tips for the IPC-HFW2549S-S-IL
Mount at 4–6 m height angled 10–20° downward — high enough to deter tampering, low enough to preserve face detail at 21m.
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 Dahua IPC-HFW2549S-S-IL covers about 14.6 m of scene width; at 10 m that grows to 29.1 m, and at 20 m to 58.2 m. Translating those numbers through EN 62676-4 pixel-density thresholds, the camera can detect a person up to 41 m, observe up to 16 m, recognise up to 8 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 Dahua IPC-HFW2549S-S-IL 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 111° horizontal FOV and 30 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 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 Dahua IPC-HFW2549S-S-IL suitable for outdoor installation?
Yes for the IP66/IP67-rated variant of this model. Bullet and dome bodies in the Dahua 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 Dahua IPC-HFW2549S-S-IL?
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 Dahua IPC-HFW2549S-S-IL consume per day?
At 4.9MP (2960×1668) resolution, 15 fps H.265 continuous recording, the IPC-HFW2549S-S-IL 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 Dahua IPC-HFW2549S-S-IL 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 8 m, observes general activity up to 16 m, and detects motion up to 41 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 Dahua IPC-HFW2549S-S-IL 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.
