Dahua NVR4104-EI Introduced by Dahua Technology, WizSense is a series of AI products and solutions that utilize an independent AI chip and a deep learning algorithm. It focuses on humans and vehicles with high accuracy, allowing users to quickly act on specific targets. Based on Dahua's advanced technologies, WizSense provides intelligent, simple, and inclusive products and solutions. Face Detection: The face detection function detects whether a human face appears in a video recording. This technology utilizes a deep learning algorithm that supports face detection, tracking, optimization, and capture, and then generates the best facial snapshots. Face Recognition: Dahua's facial recognition technology extracts features from captured faces and compares them with those in a face database to recognize the person's identity. Perimeter Protection: Automatically filters out false alarms caused by animals, rustling leaves, bright lights, etc., enabling the system to recognize secondary targets. Improves alarm accuracy. SMD Plus: Using an intelligent algorithm, Dahua Smart Motion Detection technology can categorize targets that trigger motion detection and filter motion detection alerts triggered by other targets to provide effective and accurate alarms. AI Search: Supports AI search by metadata of different targets or uploads face photos to the device and compares them with recorded faces for similarity. Allows operators to quickly and easily search multiple channels and long durations, effectively identifying when and where a person of interest appeared. Heat Map via Camera: Dahua's heat map technology displays crowd density and the probability of people appearing. Export and display crowd status in different colors. Generally speaking, crowd status is a statistic of the number of people in spatial and temporal dimensions. Quick Pick: Dahua Quick Pick technology allows users to quickly select targets of interest, such as people/vehicles, making it easier to search for SMD events.
