Extra Info
Starlight Technology
This camera is equipped with Starlight low-light imaging technology, allowing it to capture clear, colorful video in dim environments where other cameras would switch to black-and-white IR mode. Its high-sensitivity sensor works with ambient light to deliver better detail, reduced noise, and improved clarity—ideal for parking areas, hallways, or exterior entrances at night.
Smart H.265+/H.264+ Compression
Using advanced video compression algorithms, the camera dynamically adjusts bitrate and frame settings based on scene motion and complexity. Smart H.265+ can reduce storage and bandwidth requirements by up to 70% without sacrificing image quality, making it cost-effective for long-term recordings and remote streaming—especially useful in multi-camera setups or where data limits apply.
Wide Dynamic Range (WDR)
Thanks to its WDR support, the camera effectively balances exposure in scenes with both very bright and very dark areas. This makes it especially effective in environments like storefronts, entrances with large glass windows, or warehouse loading bays, where direct sunlight or shadows can otherwise obscure important details.
Built-In Intelligent Video Analytics (IVS)
The camera includes Intelligent Video System (IVS) features like tripwire and intrusion detection, which allow you to set up custom monitoring zones. These features can trigger alerts or recording events when a person or vehicle enters a defined area—ideal for perimeter security, hallways, or parking areas where proactive monitoring is needed. These analytics are fully configurable to match your specific security priorities.
Powerful Yet Affordable
Despite its rich feature set, this camera is designed to fit mid-range budgets. It delivers high-resolution video, smart motion detection, intelligent analytics, and audio support at a cost-effective price point—making it a perfect choice for schools, small businesses, offices, and residential complexes seeking professional-grade surveillance without overextending their budget.
While the IPC-HDW2831EM-AS-S2 does not feature built-in AcuPick, it supports AcuPick search functions when connected to an AI-capable Dahua NVR. The camera sends AI metadata (e.g., face detection, people counting, perimeter classifications) that the NVR uses for smart filtering and playback search.
Benefits via AI NVR Integration:
- Search by human or vehicle presence
- Filter playback using traits like mask, gender, or clothing
- Skip irrelevant footage and jump to key events instantly
- Use AI-driven logs and smart snapshots from camera metadata
