Dahua Security Camera: 4MP Turret, 2.8mm, Lite (Black) - DH-IPC-HDW2431EMP-AS-0280B-S2-AUS-BLK

Description

This 4MP fixed-lens eyeball camera combines clear image quality, smart motion detection, and a built-in mic in a vandal-resistant housing. It's great for homes or small business security setups where two-way audio isn't needed but audio recording is a plus. The starlight feature improves night performance, and its tough IP67/IK10 rating means it’s ready for harsh outdoor use.

Key Features

  • 4MP Resolution – Clear video detail for faces, vehicles, and surroundings.
  • Starlight + IR Night Vision (30m) – Captures more color at night; IR for total darkness.
  • Smart Motion Detection (IVS) – Intrusion & tripwire help filter out false alerts.
  • Built-in Mic – Records audio for better event context and evidence.
  • Fixed 2.8mm or 3.6mm Lens – Choose wider view or more focused zone.
  • MicroSD Slot (up to 256GB) – Record locally even if the network goes down.
  • Strong Build – IP67 & IK10 – Weatherproof and vandal-resistant for outdoor use.
  • Smart H.265+ Compression – Saves storage and bandwidth without losing clarity.

   

Perfect For:

  • Front porches or doorways
  • Indoor/outdoor retail shops
  • Covered carports
  • Apartment block entries
  • Backyards and garden areas
  • Cafes or small office lobbies

Install Tips

  • Choose 2.8mm lens for wide-area viewing (e.g. front porch).
  • Choose 3.6mm lens for tighter monitoring (e.g. entry gates).
  • Use Smart PSS or DMSS app for easy remote monitoring and audio playback.
  • Install under eaves or ceilings for downward-angled views.

Extra Info

Starlight Low-Light Imaging – See Color Longer at Night

Equipped with Dahua’s advanced Starlight technology, this camera offers outstanding visibility in dim conditions. It captures full-color images longer before switching to black-and-white IR mode, unlike typical night vision cameras. This is essential for identifying important scene details such as clothing color, vehicle paint, or facial features, even when ambient light is minimal—making it perfect for alleyways, entrances, or early evening surveillance.

Smart IVS Motion Detection – Smarter Alerts, Less Noise

This model supports Intelligent Video System (IVS) functions, including tripwire and intrusion detection. These virtual boundaries allow you to define specific zones or lines in the camera’s field of view. When motion is detected in these zones—especially from a human or vehicle—the system triggers an alert. This helps eliminate false notifications from irrelevant movement like leaves, shadows, or animals, ensuring your attention is only drawn to real threats.

Built-in Microphone – Audio Included

The integrated microphone allows for ambient sound recording without the need for extra wiring. It’s ideal for areas like interview rooms, storefronts, or reception areas where voice recording or ambient sound can support incident verification, identify disturbances, or complement visual footage during playback.

Smart Codec with H.265+ – Efficient Video Storage

The camera uses Smart H.265+ compression, which dynamically adjusts based on motion and scene complexity. During calm periods, less data is recorded, and during activity, important details are preserved. This intelligent encoding helps reduce both bandwidth usage and storage requirements by up to 70%, making it a cost-effective solution for long-term recording or when using limited-capacity NVRs or SD cards.

Tough Exterior Protection – Built for Real-World Environments

With IP67 weatherproofing, the camera is sealed against rain, dust, and harsh climates, ensuring year-round outdoor performance. Meanwhile, its IK10-rated metal housing offers strong protection against vandalism or impact, making it ideal for public areas, building exteriors, or locations prone to tampering. It’s designed to perform reliably—even in rugged or high-traffic environments.
