Specifications
About the Dahua SD3E405DB-GNY-A-PV1
The Dahua SD3E405DB-GNY-A-PV1 is a motorized PTZ chassis ideal for large open spaces — parking lots, stadiums, airports, and city surveillance. 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. 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
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 100° field of view spans roughly 238 meters at the camera's effective range — wide enough to monitor multiple parking rows from a single mounting point.
Entrance, lobby & vestibule
The 100° 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.
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
- •50m IR range eliminates the need for external night-time illuminators
- •Super Low Light sensor maintains color detail in near-darkness
- •100° wide field of view reduces the number of cameras needed per area
- •PTZ control enables operator-driven tracking and pre-set tours
- •100m effective range supports outdoor perimeter and parking-lot deployments
Considerations
- •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 3.7MP (2560×1440) resolution at 100° field of view. Effective identification range up to 100m 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 SD3E405DB-GNY-A-PV1
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.
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 Dahua SD3E405DB-GNY-A-PV1 covers about 11.9 m of scene width; at 10 m that grows to 23.8 m, and at 20 m to 47.7 m. Translating those numbers through EN 62676-4 pixel-density thresholds, the camera can detect a person up to 43 m, observe up to 17 m, recognise up to 9 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 2.7-13.5mm lens declared by the manufacturer.
Power & cabling
The Dahua SD3E405DB-GNY-A-PV1 draws an estimated 60.0 W under typical load (with the IR illuminator engaged where applicable), placing it in the 802.3bt Type 3 (Class 5–6, ≤60 W) budget. A single switch port supplies enough power without an injector. Cabling: stick to Cat6 STP for runs up to 80 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 SD3E405DB-GNY-A-PV1'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 SD3E405DB-GNY-A-PV1 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 SD3E405DB-GNY-A-PV1?
The camera draws roughly 60.0 W in steady-state operation, requiring a 802.3bt Type 3 (Class 5–6, ≤60 W) switch port. A single Cat6 STP cable carries both data and power up to 80 m — beyond that, add an inline extender or convert to fibre near the camera.
How much storage does the Dahua SD3E405DB-GNY-A-PV1 consume per day?
At 3.7MP (2560×1440) resolution, 15 fps H.265 continuous recording, the SD3E405DB-GNY-A-PV1 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 Dahua SD3E405DB-GNY-A-PV1 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 9 m, observes general activity up to 17 m, and detects motion up to 43 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 SD3E405DB-GNY-A-PV1 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.
