System Overview
With advanced chip, image sensor and deep learning algorithm, Dahua Ultra-AI Series network camera supports various intelligent functions and meets customers’ requirements in different scenes. Adopting excellent image processing technology, Dahua AI network camera performs well in WDR and low illuminance environment. For intelligent functions, it supports face detection, people counting, perimeter protection, video metadata (vehicle, non-motor vehicle, person detection and snapshot). The camera provides better solution to image processing and intelligent application.

People Counting
People counting adopts deep learning algorithm to detect human body target, and tracks the target in real time, which realizes independent statistics of entry number and exit number. And the accuracy rate is up to 98%.

Video Structurization
Video metadata adopts deep learning algorithm to detect vehicle, non-motor vehicle and people in the image, track the target in real time, and then capture the target and extract attributes.

Ultra WDR
Standard WDR/HDR camera can provide 120 dB dynamic range. How-ever, for some scenes with wider contrast range, 120 dB is slightly insuf-ficient. By adopting the latest technology, Dahua Cameras can provide an amazing dynamic range up to 140 dB.

Smart H.265+
Smart H.265+ is an effective coding method based on H.265. Com-paring with H.265, smart H.265+ improves efficiency more than 70% through auto scene judgement, dynamic ROI and dynamic GOP. Smart H.265+ provides better solution to save storage, bandwidth and power consumption

Dahua ePoE technology, designed internally, adopts advanced 2D-PAM3 coding modulation from physical layer, and realizes full duplex transmis-sion over 800 meters at the speed of 10 Mbps, or 300 meters at the speed of 100 Mbps via Cat 5 or coaxial cable media. Besides, it supports PoE and PoC power supply technology which has greatly simplified construction and wiring. Dahua ePoE technology offer a new way to accomplish long distance transmission between IP camera and network switch. It allows more flexible surveillance system design, improves reli-ability and saves construction and wiring cost.

Face Recognition
Once facial features are extracted from captured faces, they are stored in a database where they can be easily searched and compared against other images. Once a successful match is found, the system outputs the result. The Dahua Face Recognition camera supports a built-in database that stores up to 200,000 facial images, helping the camera achieve real-time face capture and comparison.

Perimeter Protection
Dahua’s Perimeter Protection functions significantly improved accuracy.Perimeter Protection reduces false alarms and decreases pixelcount requirements for object detection. Perimeter Protection featurescustom tripwires based on object type for automation in limited accessareas such as pedestrian or vehicle-only zones. This combination ofadvanced AI analytics and real-time alerts to a desktop or to a mobileclient reduces system requirements and resources resulting in greatersurveillance system efficiency.
