Video Metadata & PPE Detection

What is Video Metadata & PPE Detection?

Metadata refers to "data that provides information about other data". In other words, it is “data about data. ”Metadata has various purposes. It helps users find relevant information and discover resources.

Dahua Video Metadata technology with deep learning algorithm can detect, track, and capture images of people, vehicle and non-motor vehicle. It selects the best images and extracts attributes of targets to locate them immediately. In order to better enhance the value of its functions, We have added targets direction analysis and data statistics technology in version 2.0, which can be used for business analysis. We also added PPE Detection technology to detect PPE wearing and alert security personnel if necessary.
