About the Dahua SDT5A405WA-4F-B
The Dahua SDT5A405WA-4F-B is a high-speed dome PTZ that can patrol preset positions on a schedule and react to motion or analytics events. Sub-megapixel resolution is suitable only for general overview footage — useful for movement detection but insufficient for facial recognition or license-plate reading. A short-range IR illuminator (≤20 m) handles entrance vestibules, indoor corridors, and small enclosed spaces. Beyond 20 meters the IR fall-off causes faces to lose detail in pure darkness. 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.
Best use cases for this camera
Large area patrol & target tracking
PTZ control enables operator-initiated tracking of suspicious activity, scheduled tours of preset positions overnight, and forensic zoom into recorded footage. Best paired with a wide-angle "overview" camera that triggers the PTZ via analytics.
Strengths
- •PTZ control enables operator-driven tracking and pre-set tours
Considerations
- •Short IR range limits night usability to indoor or close-proximity scenarios
- •PTZ cameras only see one direction at a time — pair with a fixed overview camera to avoid blind spots

Field of View Visualization
Night Vision Performance
Daytime
Full N/A resolution at 57° field of view. Effective identification range up to 20m in good lighting conditions.
Nighttime (IR)
Built-in IR LEDs illuminate up to 18m in complete darkness. Switches to B/W mode for clear night footage.
Installation tips for the SDT5A405WA-4F-B
Mount above 4 m on a rigid pole or wall bracket — PTZ vibrations are amplified at low mounting heights and degrade image quality during pan operations.
Pair with low-cost ambient lighting (motion-triggered LED floods) to extend usable identification distance beyond the IR limit.
Coverage geometry & DORI distances
At a 5-metre standoff the Dahua SDT5A405WA-4F-B covers about 5.4 m of scene width; at 10 m that grows to 10.9 m, and at 20 m to 21.7 m. Translating those numbers through EN 62676-4 pixel-density thresholds, the camera can detect a person up to 69 m, observe up to 28 m, recognise up to 14 m, and produce identification-grade detail (the ≥250 px/m bar used by Polish and EU courts as evidentiary) up to 7 m. Effective range above the identify threshold relies on supplementary lighting or a longer-focal-length optic — the geometry above assumes the 10-50mm lens declared by the manufacturer.
Power & cabling
The Dahua SDT5A405WA-4F-B draws an estimated 30.0 W under typical load (with the IR illuminator engaged where applicable), placing it in the 802.3at (Class 4, ≤30 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. The Dahua SDT5A405WA-4F-B's PTZ pan range can sweep into neighbouring properties or public roads; document allowed pan limits in the installation record and configure privacy masks (see Dahua's web-UI under "Privacy Mask") for any window or doorway you cannot legally surveil.
Installer time & cost (rough estimate)
A typical EU installer quotes 5–6 h of labour per ptz camera of this class (approximately €225–€275 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 SDT5A405WA-4F-B suitable for outdoor installation?
Dahua PTZ models are generally designed for outdoor use with IP66 ingress rating and -30°C to +60°C operating range. Mount on a rigid pole at ≥ 4 m to dampen wind-driven vibration that would degrade the live image during pan operations.
What PoE class powers the Dahua SDT5A405WA-4F-B?
The camera draws roughly 30.0 W in steady-state operation, requiring a 802.3at (Class 4, ≤30 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.
