Dahua IPC-HDW3449H-AS-PV-S5 - 4MP 2.8mm Dual Light WizSense IP Camera 

Dahua IPC-HDW3449H-AS-PV-S5 4MP 2.8mm Dual Light WizSense IP camera 

Optics and image sensor

This camera is equipped with a 2.8 mm fixed lens combined with a 1/2.7" CMOS sensor, offering an optimised compromise between a wide field of view and usable details for detection and identification. The horizontal viewing angle of 101°, vertical viewing angle of 53° and diagonal viewing angle of 120° allow large areas to be covered with a single camera, reducing the number of cameras required. High sensitivity, with a minimum illumination of 0.003 Lux at F1.0, ensures usable images in very low light conditions, reducing the systematic use of infrared and improving the reproduction of night scenes.

Resolution, video stream and compression

The maximum resolution of 4 MP (2688 x 1520) is available at up to 25/30 fps, ensuring smooth motion reproduction, suitable for environments where detailed analysis is essential. The camera supports up to three simultaneous streams, allowing bandwidth and storage to be optimised by adapting the definition to each use (recording, live viewing, mobile viewing). H.265, H.264, H.264H, H.264B and MJPEG codecs ensure high integration flexibility, with a significant reduction in bandwidth consumption and storage capacity requirements, while maintaining high image quality.

Low-light performance and integrated lighting

The camera incorporates an infrared illuminator and a warm light, each with a range of 30 metres, to ensure uniform coverage in total darkness. The combination of an IR LED and white light allows the lighting to be adapted to the scenario: discreet infrared vision or visible lighting for deterrence and colour enhancement. The minimum illumination of 0.003 Lux at F1.0 allows the camera to switch to night mode later, providing a colour image for longer in very low-light environments.

Image enhancement and processing

Advanced processing features include 120 dB WDR, 3D NR noise reduction, BLC backlight compensation, HLC highlight compensation, and a rotation mode to accommodate vertical or narrow scenes. 120 dB WDR ensures effective management of high dynamic range scenes, such as building entrances or mixed indoor/outdoor areas. 3D NR optimises the signal-to-noise ratio in dark scenes, reducing video noise and the weight of compressed streams. Digital watermarking enhances the integrity of recordings for traceability and compliance purposes.

Artificial intelligence and video analysis features

The camera incorporates intelligent analysis functions such as line crossing, intrusion detection in an area and scene change detection, enabling proactive surveillance and the generation of targeted alerts. AI and SMD 4.0 support enables more accurate classification of targets (people, vehicles, other objects), reducing the number of false alarms related to irrelevant movements. The one-click arming and disarming function facilitates operational management, quickly adapting the level of surveillance to the temporal or contextual needs of the site.

Audible and visual alarm and active deterrence

The device is equipped with an audible and visual alarm, with integrated red and blue lights, to reinforce deterrence when events are detected. This visual and audible signalling complements the intelligent analysis, transforming the camera into an active element of the security system. It allows for immediate response to intrusions or abnormal behaviour, alerting individuals present locally while generating alerts to the supervision station.

Mechanics, settings and environment

The camera offers great installation flexibility thanks to its comprehensive mechanical adjustment options: pan from 0° to 360°, tilt from 0° to 78° and rotation from 0° to 360°, allowing the field of view to be precisely adjusted regardless of the mounting method. The housing meets IP67 protection standards, ensuring resistance to dust and temporary immersion, making it suitable for demanding outdoor environments. The operating temperature range of -40°C to 60°C ensures high reliability in extreme climates without compromising performance.

Power supply, consumption and connectivity

The device can be powered by 12 V DC or PoE, with a maximum power consumption of 3.7 W or 4.8 W depending on the configuration, simplifying integration into existing network infrastructures and reducing cabling costs. The audio and alarm interfaces each offer one input and one output (Audio I/O 1/1, Alarm I/O 1/1), allowing the integration of microphones, external speakers, sensors and actuators. This connectivity expands the possibilities for scenarios such as intercom, voice message broadcasting, siren triggering or additional lighting devices.

Storage, compatibility and system integration

A micro SD card slot, compatible with up to 256 GB, allows for local video recording, either as a backup solution in case of network connection loss or as the primary storage for decentralised installations. ONVIF compatibility (S/G/T profiles) and the CGI interface ensure easy integration into most video surveillance systems and VMS platforms, promoting interoperability with equipment from different manufacturers. This compliance with standards allows the camera to be deployed in existing architectures without any particular constraints.

Physical characteristics and dimensions

Measuring 11.09 cm x Φ12.2 cm and weighing 0.75 kg, the camera has a compact design that makes it easy to install on walls, ceilings or poles, while offering sufficient volume to ensure good heat dissipation and mechanical robustness. Its physical characteristics allow for discreet integration into most professional and residential environments, while ensuring stable and durable mounting.
