Architecture overview

Integration between the SmartFace facial recognition platform and Nx Witness VMS is performed through the SmartFace Analytics plugin and SmartFace Camera services installed on Nx Witness server.

SmartFace Analytics plugin running within Nx Witness is responsible for the communication and transformation of data received from SmartFace. SmartFace Camera services installed on Nx Witness server sends processed frames into SmartFace Platform. The Camera services perform also lightweight processing in form of tracking of detected faces. SmartFace Platform detects faces on incoming frames, extracts demographic data from the detected faces and matches the faces against watchlists stored in SmartFace. All information obtained by SmartFace is sent back to Nx Witness. SmartFace Analytics plugin then processes data coming from SmartFace Platform, so that Nx Witness can display it.

For the integration it is necessary that the SmartFace Platform is also properly configured. For more information how to install and configure the SmartFace and NX Wintess integration, see Installation of Nx Witness integration.
