Dahua SD2C400NA-B-PV-PRO 4MP WizColor WizSense PT Network Camera

The Dahua SD2C400NA-B-PV-PRO 4MP camera is a smart pan-and-tilt IP surveillance camera designed for homes, offices, shops, warehouses, compounds, parking areas, and perimeter security where wider coverage, full-colour night monitoring, and intelligent detection are important. It records in 4MP 2560 × 1440 resolution, uses WizColor technology for brighter full-colour images in low-light environments, and supports pan-and-tilt movement to cover a larger surveillance area than a fixed camera. As part of Dahua’s WizSense range, it also features SMD 3.0, perimeter protection, Smart Tracking Lite, two-way talk, preset patrol, H.265 compression, and IP66 weather protection, making it a strong option for modern indoor and outdoor CCTV systems.

Product Features

4MP High-Definition Video Quality

The camera captures video at 2560 × 1440 resolution, delivering sharper and more detailed footage than standard 2MP surveillance cameras. This makes it suitable for entrances, compounds, shop fronts, office spaces, parking areas, and building exteriors where clearer subject detail is important.

WizColor Technology for Full-Colour Low-Light Monitoring

Dahua WizColor technology helps the camera produce brighter and more detailed full-colour footage in low-light conditions, improving visibility at night compared to conventional black-and-white infrared-only cameras. This is useful for compounds, gates, parking areas, and outdoor business security points where colour evidence matters.

Pan-and-Tilt Coverage for Wider Surveillance

Unlike a fixed camera, the SD2C400NA-B-PV-PRO supports PT movement, allowing it to monitor a broader area from a single installation point. This makes it a good choice for open compounds, retail fronts, warehouse surroundings, driveways, and reception areas where wider surveillance coverage is needed.

Smart Tracking Lite for Automatic Target Following

The camera supports Smart Tracking Lite, enabling it to automatically follow detected moving targets within its coverage area. This helps improve incident monitoring and can be useful in active surveillance environments where subjects move across the scene.

SMD 3.0 and Perimeter Protection

As a WizSense model, the camera supports SMD 3.0 and perimeter protection, helping distinguish relevant human and vehicle targets from general movement. This reduces false alarms and makes alerts more useful for home and business surveillance.

Two-Way Talk with Built-In Microphone and Speaker

The camera includes a built-in microphone and speaker, allowing two-way audio communication and audio recording. This is useful for gates, entrances, reception areas, and locations where live communication with visitors or staff may be needed.

H.265 Compression for Lower Storage and Bandwidth Use

Support for H.265 video encoding helps reduce storage requirements and network bandwidth consumption while maintaining clear image quality, making the camera more efficient for continuous recording on compatible NVR systems.

Supports microSD Card Storage up to 256GB

The SD2C400NA-B-PV-PRO supports microSD card storage up to 256GB, allowing local edge recording directly on the camera. This is useful for backup recording or installations where local storage is required.

Preset Patrol for Automated Monitoring

The camera supports preset patrol, allowing it to move automatically through saved viewing positions. This helps cover multiple important zones such as gates, driveways, compound corners, and entrances without manual repositioning.

IP66 Weatherproof Protection

Its IP66-rated housing helps protect the camera against dust and water, making it suitable for outdoor and indoor CCTV installation in exposed environments such as compounds, parking areas, building exteriors, and perimeter walls.

Flexible Installation with PoE and 12V DC Power

The camera supports 12V DC power and PoE (802.3af), giving installers flexible deployment options and helping simplify cabling in IP surveillance systems.
