The Face Big Data Module uses the analysis capabilities of intelligent face devices to compare face images analyzed from videos against the face database, matching the images to specified similarities, and releasing alarms. It supports recording and searching through all face images to quickly identify a person, releasing early warnings for detected fugitives and key persons for police officers to effectively combat criminals. At the same time, it uses face clustering technology to generate a face big data pool, which can produce one archive for each face, excavating the behaviors of key persons for early warning and effective control.

> Search by image: Search for the face image in the face database, passerby database, passerby archives, and more, and have results returned in seconds.
> Redlist: People added to the redlist cannot be searched and found. This helps protect the privacy of special groups of people or designated people.
> Person arming and control: Add face images to the face database for arming and control. When the face recognition succeeds, an alarm record will be generated, and the record will be sent to the face big data module in seconds.
> One face one archive: Create an archive for each image of the same face, differentiate each image with time, space and identity information to analyze the movement path and the frequency with which a person produces certain activities.
> Abundant tactics: Uses one face one archive and big data analysis technologies to calculate and analyze massive amounts of face records, and to search for results that meet your requirements, such as companion search, frequency analysis, gathering analysis, analysis based on space and time, and analysis of first appearance, disappearance in N days, and on vehicles that only come out in the night.
