Descrizione
Specifications Dahua NVR IP 8PoE 8 channels 1U 12MP 1HDDs with AI WizSense NVR2108HS-8P-I2 adopts WizSense techhnology, independent AI chip and deep learning algorithm, focuses on human and vehicle with high accuracy, enabling users to fast act on defined targets. NVR2108HS-8P-I2 provides functions such as local live view, multi-screen display, real-time storage on local HDD, fast operation by mouse, and remote management and control. This product is suitable for face detection and recognition at entrances and exits, and perimeter protection of people and vehicles. Face detection feature detects if there is any human face appearing in the video. This technology adopts a deep learning algorithm to support face detection, tracking, optimization and capturing, and then output the best face snapshot. Dahua Face Recognition technology extracts the features of captured faces and compares them with those in face database to recognize the person identity.
Perimeter protections automatically filters out false alarms caused by animals, rustling leaves, bright lights, etc. Enables system to perform secondary recognition for the targets, improving alarm accuracy. With intelligent algorithm, Dahua Smart Motion Detection technology can categorize the targets that trigger motion detection and filter the motion detection alarm triggered by non-concerned targets to realize effective and accurate alarm. The NVR supports AI seach by metadata of different targets or uploading face pictures to device and comparing them with recorded faces by similarity. It enables operators to quickly and easily search through multi channels and long duration, efficiently find out when and where a person of interest appeard. The NVR is equipped with a smart fan to achieve high cooling efficiency. It automatically turns on or turns off according to CPU and ambient temperature. The fan is long-lasting and low noise, reducing maintenance costs and improving the user experience.
