Extra Info
Specialized Corner-Mount Design
Unlike typical dome or bullet cameras, this model is purpose-built for corner installation, allowing it to provide true wall-to-wall and floor-to-ceiling visibility. Its unique design eliminates typical blind spots found in corners, making it ideal for elevators, holding cells, psychiatric facilities, or small retail rooms where full coverage and discrete placement are critical.
Anti-Vandal & Tamper-Resistant Housing
With an IK10+50J rating, this camera goes beyond standard vandal resistance. It can endure high-impact force and resist tampering attempts, ensuring uninterrupted operation in high-risk environments like correctional facilities, transit stations, or public areas prone to vandalism or abuse.
940nm Invisible IR Illumination
Equipped with 940nm infrared LEDs, the camera provides covert night vision capabilities. Unlike 850nm IR, this wavelength is completely invisible to the human eye, enabling discreet surveillance in low-light or dark conditions without drawing attention or disturbing occupants—especially important in residential, clinical, or sensitive environments.
Advanced AI Analytics
Featuring deep learning AI, this camera accurately detects and classifies humans and vehicles, significantly reducing false alarms caused by irrelevant motion like wind, animals, or shadows. It also supports people counting and queue analysis, making it suitable for crowd control, occupancy monitoring, or commercial insights in spaces like hospitals, government offices, and retail counters.
Smart Video Compression
Using Smart H.265+ and H.264+ compression, the system dynamically adjusts encoding based on motion and scene complexity. This allows up to 70% reduction in storage and bandwidth usage, helping you maintain high-quality footage while reducing costs—ideal for systems with long retention periods or limited bandwidth availability.
AcuPick – Smart Search (With AI NVR)
While the camera itself doesn’t process AcuPick, pairing it with a compatible Dahua AI NVR unlocks this intelligent search function. AcuPick uses AI-classified human or vehicle presence to help you instantly find critical moments in surveillance footage—no need to scrub through hours of video.
Benefits with AI NVR Integration:
- Search by person or vehicle in seconds
- Filter by color or shape traits (e.g. red shirt, white car)
- Skip irrelevant footage and reduce review time
- Ideal for retail, driveways, public areas, or gated entries
