Dahua 16-channel 4K ePoE Network Video Recorder

The Dahua DHI-NVR4216-16P-I combines Analytics+ algorithms with  Dahua's ePoE technology into an all-in-one network video recorder. This NVR uses a powerful multi-core processor to provide 4K resolution processing for applications where impeccable image details are required. In addition, the NVR can be employed as edge storage, central storage, or backup storage with an intuitive shortcut operation menu for remote management and control. The Dahua Analytics+ algorithms significantly improve accuracy and reliability, as compared to standard intelligent features, to achieve precision human facial analysis, and support two (2) channels of real-time face recognition based on a database that stores up to 20,000 faces. The NVR also offers advanced perimeter protection that distinguishes between human and vehicular violations on up to four (4) channels simultaneously. The DHI-NVR4216-16P-I is ideal for applications that require entrance/exit management, where knowing who is coming and going is a valuable asset.

Perimeter Protection

Dahua Analytics+ includes Tripwire and Intrusion functions that offer custom tripwires based on object type for automation in limited access areas. Perimeter Protection requires less pixels to detect an object to deliver improved accuracy and decreased false alarms due to lights, weather, trees, or animals. 

Real-time Face Recognition

Analytics+ performs real-time facial recognition on up to two (2) streaming video channels simultaneously. The server captures and analyzes facial features to determine gender, age, expression, glasses, moustache, and mask, and then can record the faces and store the associated structured data. The server also filters incoming video to display faces that match target features. 

Stranger Mode

The NVR supports two facial detection modes: Common and Stranger. In Stranger mode, when the NVR detects a face not stored in the device's database, it can trigger an alarm, a buzzer, take a snapshot, or initiate recording. It also incorporates a Similarity Threshold, where the server triggers an alarm for a face that does not match a minimum recognition level. The Stranger Mode and the Similarity Threshold are designed for critical infrastructure sites where access control is of vital importance.

Efficient Search

The NVR searches images by facial features to improve search efficiency. The server support uploading and storing 20,000 facial images for comparison with recorded faces. This search capability allows operators to quickly and easily search multiple channel recordings to determine when and where a person of interest appeared in a recording.

Face Database Management

In addition to the 20,000 facial images, the NVR database also stores names, genders, birthdays, nationality, address, and ID information associated with each facial image. The NVR also offers powerful and configurable database management features that can be applied to each face recognition channel independently. 

Smart H.265+

Smart H.265+ is the optimized implementation of the H.265 codec that uses a scene-adaptive encoding strategy, dynamic GOP, dynamic ROI, flexible multi-frame reference structure and intelligent noise reduction to deliver high-quality video without straining the network. Smart H.265+ technology reduces bit rate and storage requirements by up to 90% when compared to the H.264 video compression standard.
