The Dahua IPC-PDW31259-A180-AS-PV-ANZ-S2 is an advanced 12MP TiOC Duo panoramic network camera engineered to monitor wide areas with fewer cameras and fewer blind spots. Using two 6MP image sensors and dual 2.8mm fixed lenses, the camera produces a seamlessly stitched 5000 × 2500 panoramic image with an exceptionally wide 180° horizontal and 78° vertical field of view.
This wide-area coverage makes the camera ideal for building frontages, driveways, loading areas, warehouses, retail premises, schools, commercial facilities, car parks and other locations where a conventional single-lens camera may not provide sufficient coverage. By replacing multiple standard cameras in suitable applications, it can help simplify installation, reduce cabling and provide operators with a more natural overview of the monitored area.
Detailed 12MP Panoramic Imaging
The camera outputs a maximum 12MP resolution of 5000 × 2500 at up to 20 frames per second. Its large F1.0 aperture and sensitive 1/2.5-inch CMOS imaging system are designed to capture detailed footage across challenging lighting conditions.
A 120dB Wide Dynamic Range helps preserve detail when bright and dark areas appear in the same scene, such as entrances, loading bays and areas facing direct sunlight. Additional image-processing features include 3D digital noise reduction, backlight compensation, highlight compensation, defog, scene self-adaptation and configurable regions of interest.
Smart Dual Light with 30-Metre Range
Dahua Smart Dual Light technology combines infrared and warm-white illumination in the same camera. Both illumination modes provide a maximum range of approximately 30 metres.
The camera can operate using discreet infrared illumination during normal night-time monitoring and activate its warm lights when an intelligent event occurs. This allows the camera to capture useful full-colour evidence when a person or vehicle enters a monitored area while limiting unnecessary continuous white-light operation.
WizSense AI Detection
The IPC-PDW31259-A180-AS-PV-ANZ-S2 incorporates Dahua WizSense artificial intelligence to provide more accurate event detection and reduce unwanted alerts.
SMD 4.0 can distinguish people and motor vehicles from other movement, helping to filter out false alarms caused by animals, moving vegetation, rain and changes in lighting. Its intelligent perimeter-protection functions include:
- Intrusion detection
- Tripwire detection
- Stay detection
- Loitering detection
- Human and vehicle classification
- Full-image face detection
- Motion and scene-change detection
- Audio abnormality detection
The camera also supports electronic PTZ functionality, allowing it to enlarge and track targets associated with intelligent alarm events within the panoramic image.
AcuPick Intelligent Search
When used with a compatible Dahua AcuPick recorder, the camera can assist operators in quickly locating people, animals and motor vehicles within live or recorded footage. This can substantially reduce the time required to review recordings after an incident compared with manually searching through hours of video.
Smart Search support also enables compatible Dahua NVRs to refine intelligent event searches and merge related event footage for more efficient playback and investigation.
Active Deterrence
Rather than only recording an incident, the camera can actively warn an intruder that they have been detected. Its TiOC active-deterrence functions include flashing red and blue warning lights, built-in speakers and configurable audible alarms.
The warning-light duration and flashing frequency can be adjusted to suit the installation. The camera includes multiple alarm sounds and also supports imported custom audio messages, allowing site-specific warnings to be played when an intelligent event is triggered.
Two-Way Audio
Built-in dual microphones capture sound around the camera, while the integrated speakers support audible warnings and two-way communication. When configured with a compatible Dahua recorder or platform, an authorised user can listen and speak through the camera using supported software or the DMSS mobile application.
The camera also provides separate audio input and output connections for integration with compatible external audio equipment.
Flexible Recording and Integration
Efficient H.265, Smart H.265+ and AI-based compression technologies help reduce bandwidth and storage consumption while maintaining image quality. The camera supports three video streams, allowing separate settings to be used for recording, live viewing and remote access.
Recordings can be stored on a compatible Dahua network video recorder, network-attached storage device, FTP server or a locally installed microSD card with a capacity of up to 512GB.
ONVIF Profile S, G, T and M support provides broader integration with compatible third-party video-management and recording systems. For the full range of intelligent functions, active deterrence and AcuPick capabilities, pairing the camera with a compatible Dahua WizSense or WizMind NVR is recommended.
Built for Outdoor Installation
The camera has a robust metal enclosure with an IP67 weather-resistant rating, protecting it against dust and water ingress. It is designed to operate in temperatures ranging from -40°C to +60°C, making it suitable for a broad range of Australian indoor and outdoor environments.
Power can be supplied through 12V DC or PoE+, allowing video, audio, data and power to be carried over a single compatible network cable.
