Video analytics module installation
Flussonic Watcher supports video analytics functions including face recognition and ANPR (automatic number plate recognition). The video analytics module is not installed when you install Watcher, so you should install it manually only on the server(s) where the recognition will run.
The video analytics module can work both in Cluster and Single mode of Flussonic Watcher installation. In a Cluster installation, the recognition module works on a streamer where Flussonic Media Server must be installed first. If you use a Single server, install Flussonic Media Server and Watcher before you install the recognition system. See Watcher installation ways for details on the two installation modes.
Connect camera(s) to detect faces or vehicle numbers from to the streamer. System requirements to the server that runs video analytics are given below:
