The N8 Series AcuPick NVRs offer outstanding performance and highgrade recording technology that make it ideal for IP video security applications. Its powerful processor supports high access and forwarding bandwidth and strong decoding capabilities to produce unimpeded streams. Thanks to its built-in analytics chip and Dahua's advanced deep learning algorithms, the NVR supports a variety of analytics functions, such as AcuPick, high-precision Face Detection+, and Perimeter Protection to shorten the response time to events and make videos more interactive. This NVR is compatible with numerous third-party devices, making it a great solution for security systems that work with Video Management Software (VMS).
Dahua effectively utilizes both front-end and back-end intelligence to realize AcuPick. AcuPick technology is a true video search engine that can quickly locate the information you need. Use it to find a lost individual, locate a specific vehicle, or pinpoint evidence of a suspect who's damaged another's property.
Dahua Analytics+ includes Tripwire and Intrusion functions that offer custom tripwires based on object type for automation in limited access areas. Perimeter Protection requires fewer pixels to detect an object to deliver improved accuracy and decreased false alarms due to lights, weather, trees, or animals.
The NVR uses Local Fisheye Dewarp for up to 4 channels2 and Web Fisheye Dewarp3 to reduce distortion from circular panoramic perspectives. These features provide customized modes for various configurations, amplifying both live and playback footage and providing scene modification options. Each dewarping method offers different options for fine-tuning each scene.
Face Detection technology captures a human face in a digital image and then selects the best image and outputs a snapshot of the face.
Face Detection+ technology identifies, tracks, and captures a human face in a digital image and then selects the best image and outputs a snapshot of the face. This technology identifies key facial features and obtains the contours of detected faces.
The built-in IVS features people counting and heat map functionality, advanced features that add business intelligence to your security system. Intelligent Analysis tracks and stores daily, weekly, monthly, and yearly people flow through a defined scene and produces a configurable report. The system uses this data to produce a Heat Map, a two-dimensional representation of data that provides an immediate visual summary of activity. People Counting and Heat Maps can identify the most active areas of a retail space providing valuable data analysis for commercial applications.
Automatic License Plate Recognition
The NVR automatically captures and stores vehicle license plate images from a dedicated license plate capture camera connected to the NVR. During playback, an operator can perform a license plate search by Time and Date to view thumbnail images of all plates captured during the specified time period. License plate capture technology offers effective entrance/exit management, traffic monitoring, and parking lot monitoring.
Smart Motion Detection+
Smart Motion Detection, a component of Dahua's Analytics+ technology, improves alarm accuracy and decreases the number of false alarms. The advanced SMD algorithm analyzes a scene for human or vehicle motion, while filtering out other motion due to trees, leaves, animals, weather, and triggers an alarm when detected.
