The Dahua SD3E405DB-GNY-A-PV1 delivers a compact 4MP TiOC WizSense PTZ camera designed for residential and commercial perimeter protection. Equipped with Smart Motion Detection 3.0, it intelligently distinguishes between humans and vehicles to minimise false alarms caused by animals or environmental factors. It also includes active deterrence with red and blue strobe lights, customisable audio alerts, and a built-in microphone and speaker for two-way communication. With a 5x optical zoom ranging from 2.7mm to 13.5mm, combined with IR illumination up to 50 metres and warm light up to 30 metres, it maintains vivid imaging around the clock.
Key Features
5x Optical Zoom: Adjustable focal length from 2.7mm to 13.5mm enables precise subject identification at a distance.
Smart Motion Detection 3.0: Accurately detects human and vehicle movement to reduce false alarms from animals and environmental triggers.
Active Deterrence: Red and blue strobe lights with customisable voice alerts activate on perimeter breach to proactively deter intruders.
Two-Way Audio: Built-in microphone and speaker allow real-time audio communication with anyone on-site.
Hybrid Night Vision: IR range up to 50m combined with 30m warm light illumination ensures clear imaging in low-light and zero-light conditions.
PTZ Control: Pan, tilt, and zoom functionality provides flexible wide-area surveillance coverage from a single installation point.
Combining active deterrence with motorised PTZ control and AI-based target filtering, the Dahua SD3E405DB-GNY-A-PV1 is a 4MP TiOC WizSense PTZ network camera suited to perimeter protection, large open sites, and unmanned monitoring environments where a single fixed camera falls short. Featuring a 5x motorised varifocal lens spanning 2.7mm to 13.5mm, the camera shifts between wide-scene awareness and detailed subject identification without physical repositioning. Smart Motion Detection 3.0 uses deep learning to restrict alerts to confirmed human and vehicle targets, while the built-in red and blue strobe lights and customisable audio alarms activate the moment a perimeter breach is registered. Smart Dual Light technology manages both IR illumination up to 50 metres and warm white light up to 30 metres, delivering genuine full-colour footage in low-light conditions. With Auto Tracking Lite, two-way audio, 300 preset positions, and an IP66-rated housing rated from -30 degrees C to +60 degrees C, this camera handles demanding outdoor deployments across the full range of Australian conditions.
Key Capabilities
5x Optical Zoom with Wide DORI Coverage
The 2.7-13.5mm motorised varifocal lens spans a horizontal field of view from 95.6 degrees down to 30.0 degrees. DORI distances reach 270 metres for detection and 27 metres for identification, giving operators genuine subject-level clarity at range without the need for a second camera.
Smart Motion Detection 3.0
Deep learning AI classifies moving objects as human or vehicle targets only, filtering out animals, foliage, and environmental triggers that cause nuisance alerts on conventional motion-based systems. This keeps monitoring practical on busy outdoor sites such as warehouses, car parks, and construction yards.
Active Deterrence
Built-in red and blue strobe lights trigger automatically on breach detection, supported by up to 11 sound alarm types including 10 customisable voice messages. This visible and audible response interrupts an intrusion in progress rather than simply recording it, which is a material advantage over passive cameras at perimeter-critical sites.
Smart Dual Light Technology
The camera automatically selects between IR illumination up to 50 metres for low-power monochrome coverage and warm white light up to 30 metres for full-colour night footage. Colour night imaging aids identification of clothing, vehicle colour, and distinguishing physical features in a way that standard IR cannot.
Auto Tracking Lite
On detecting a confirmed human or vehicle target, the PTZ mechanism tracks the subject continuously across the scene without operator input. For unmanned sites or after-hours monitoring, this keeps a moving subject in frame for the duration of an event rather than capturing a brief entry and losing them to a static field of view.
Two-Way Audio
A built-in microphone and speaker allow security personnel or site managers to communicate directly through the camera in real time. This supports live verbal warnings to trespassers, remote visitor management at entry points, and coordination with on-site staff without requiring a separate intercom device.
Best For
Warehouse and Distribution Centres: The 5x zoom and wide pan-tilt range allow a single SD3E405DB-GNY-A-PV1 to cover expansive floor areas, with auto tracking keeping moving targets in frame across large distances without additional fixed cameras.
Outdoor Perimeter Monitoring: IP66 weather resistance and an operating range of -30 degrees C to +60 degrees C keep performance consistent across harsh Australian outdoor environments, including coastal, tropical, and alpine conditions.
Retail Stores and Commercial Premises: Active deterrence strobes and audio alarms respond immediately to after-hours breaches, offering a proactive response layer that recording-only installations cannot provide.
Car Parks and Public Access Areas: Smart Motion Detection 3.0 filters vehicle and pedestrian movement from environmental noise, keeping alert volumes manageable in areas where conventional motion detection would generate constant false positives.
Remote and Unmanned Sites: Customisable voice warnings and auto tracking allow this camera to respond autonomously to intrusions, making it suited to construction sites, rural holdings, or facilities with no permanent on-site security presence.
Why Choose the SD3E405DB-GNY-A-PV1
A fixed camera records what enters its field of view. The SD3E405DB-GNY-A-PV1 tracks, deters, and communicates, consolidating three security functions into a single weatherproof unit. The 5x optical zoom with DORI detection reaching 270 metres means this camera provides usable situational coverage across large sites where multiple fixed cameras would otherwise be required. The Smart Dual Light system delivers genuine colour night footage when scene conditions allow it, rather than falling back to flat monochrome IR imagery as cheaper alternatives do. Up to 300 presets and PoE+ (802.3at) support make integration into existing IP networks efficient. The 10 customisable voice alarm messages allow site-specific warnings to be programmed in, which is a level of flexibility rarely found in compact PTZ units. Security Wholesalers supplies the SD3E405DB-GNY-A-PV1 as part of its curated Dahua TiOC range, ensuring trade and commercial buyers receive genuine stock backed by accurate technical support for Australian installations.
Buyer Decision Tips
Buyer Tip: This camera requires PoE+ (802.3at) to operate at full capacity, with a maximum draw of 15W. Standard PoE (802.3af) is capped at 15.4W delivery but can operate unreliably near this threshold. Confirm your switch or injector is 802.3at rated before installation. Undervolting can suppress active deterrence functions including the strobe and audio alarm outputs, which defeats a key feature of this unit.
Buyer Tip: Warm white light illumination covers up to 30 metres for full-colour night footage. IR extends to 50 metres but produces monochrome output. If colour identification at distances beyond 30 metres is a requirement for your site, factor this into your mounting height and positioning plan before installation. Adjusting PTZ camera placement after installation is significantly more involved than repositioning a fixed unit.
Key Features & Technical Specifications
Image Sensor
1/2.8-inch 4 Megapixel CMOS
Resolution
2560 x 1440 (4MP)
Lens Type
Motorised varifocal, 2.7mm to 13.5mm (5x optical zoom)
The 5x optical zoom combined with pan and tilt movement across 355 degrees allows a single camera to monitor large floor areas and switch between wide-scene views and close-up identification without physical repositioning, reducing the total number of cameras required on large sites.
Retail Stores and Commercial Properties
Built-in strobe lights and customisable audio alarms activate automatically on breach detection, providing an active deterrence response to shoplifting and after-hours intrusion attempts without requiring security staff on-site to manage the event.
Outdoor Perimeters in Harsh Environments
IP66 weatherproofing and an operating temperature range of -30 degrees C to +60 degrees C sustain performance across tropical, coastal, and inland Australian climates, including exposure to rain, dust, and extended periods of direct heat that cause early failure in lower-rated housings.
Car Parks and High-Traffic Outdoor Areas
Smart Motion Detection 3.0 classifies targets as human or vehicle before generating an alert, reducing the alert volume that conventional motion-based cameras produce in environments with variable vehicle movement, wind-affected vegetation, and changing light conditions.
Unmanned and Remote Sites
Auto Tracking Lite keeps confirmed human and vehicle targets in frame autonomously, while customisable voice messages deliver site-specific verbal warnings without operator intervention. This suits construction sites, rural properties, and facilities that are not permanently staffed overnight.
Choosing the Right Model
Choose this model if: You need a compact outdoor PTZ with active deterrence, AI-filtered human and vehicle detection, full-colour night imaging, auto tracking, two-way audio, and weatherproof construction in a single unit for perimeter or large-area monitoring.
Choose a different model if: Your site requires coverage of a fixed, narrow angle only and PTZ movement is not needed. A fixed turret or bullet camera at a lower cost per unit would be more efficient for single-point coverage where tracking and zoom adjustment provide no practical benefit.
FAQs
What is the difference between the IR range and the warm white light range on the SD3E405DB-GNY-A-PV1? This camera carries 2 separate illuminators. The IR illuminator reaches up to 50 metres and produces monochrome footage in complete darkness. The warm white light illuminator reaches up to 30 metres and delivers full-colour footage in low-light or dark conditions. The Smart Dual Light system selects between them automatically based on scene brightness, so both operate independently rather than simultaneously.
Does this camera work with a standard PoE switch? No. The SD3E405DB-GNY-A-PV1 requires PoE+ (802.3at), which supports up to 30W per port. Standard PoE (802.3af) is limited to 15.4W and cannot reliably deliver the 15W maximum draw this camera requires under full load. Using a standard PoE port risks instability and may prevent active deterrence features including the strobe lights and audio alarms from operating correctly.
How does Auto Tracking Lite work on this camera? Once the WizSense AI engine identifies a human or vehicle target in the field of view, the PTZ mechanism automatically pans and tilts to keep the subject centred in frame as they move. This operates without manual input. Tracking is limited to confirmed AI-classified targets rather than any motion event, which reduces unnecessary camera movement on busy outdoor sites.
Can the audio alarm messages be customised to suit our specific site? Yes. The active deterrence system supports up to 11 sound alarm types, which includes 10 customisable voice messages. Site managers can record and upload location-specific warnings such as trespass notices, site entry restrictions, or emergency instructions. This replaces generic alarm tones with targeted messaging relevant to the installation.
How many preset positions does the SD3E405DB-GNY-A-PV1 support? The camera supports up to 300 preset positions. Presets allow operators to define specific viewing angles and move the camera to those positions instantly on demand or as part of an automated patrol sequence. For multi-zone sites with several areas of interest, this reduces operator workload and speeds up incident response.
Is this camera suitable for outdoor installation in Australian conditions? Yes. The IP66 rating confirms full protection against dust ingress and powerful water jets from any direction. The operating temperature range of -30 degrees C to +60 degrees C covers the full spectrum of Australian climates, including far north tropical regions, arid inland zones, and cooler southern and alpine environments.
What video compression formats does this camera support, and which should I use? The SD3E405DB-GNY-A-PV1 supports Smart H.265+, H.265, Smart H.264+, H.264H, H.264B, H.264, and MJPEG for sub-stream. Smart H.265+ delivers the most efficient compression, reducing storage consumption and network bandwidth significantly compared to standard H.264 while maintaining comparable image quality. This is the recommended setting for sites with limited NVR storage capacity or constrained network infrastructure.
Where can I purchase the SD3E405DB-GNY-A-PV1 and access technical support in Australia? This camera is available through Security Wholesalers, which supplies it as part of a curated Dahua TiOC range for trade and commercial buyers. Purchasing through a specialist distributor ensures you receive genuine stock with access to accurate technical guidance on compatibility, PoE+ power requirements, and NVR integration rather than relying on generic product listings without local support.
