FindFace Multi Data Storages

In this section:

List of Storages

FindFace Multi uses the following data storages:

• Tarantool-based feature vector database that stores object feature vectors and events.

• PostgreSQL-based main system database ffsecurity that stores internal system data, cards, user accounts, and camera settings.

• The /var/lib/findface-security/uploads directory that stores uploaded card photos, video files, full frames of events and counters, and object thumbnails.

• The /var/lib/ffupload/ directory that stores such event artifacts as normalized object images.

  Note

  It also stores video chunks if you are using Video Recorder.

• (Only with Video Recorder) MongoDB-based database that stores meta-information of the video chunks, including their exact location in the storage, /var/lib/ffupload/.

Feature Vector Database Galleries

There are the following galleries in the Tarantool-based feature vector database:

• ffsec_body_events: feature vectors extracted from bodies detected in the video.

• ffsec_body_objects: feature vectors extracted from body images uploaded to the card index.

• ffsec_body_clusters: centroids of body clusters.

• ffsec_car_events: feature vectors extracted from cars detected in the video.

• ffsec_car_objects: feature vectors extracted from car images uploaded to the card index.

• ffsec_car_clusters: centroids of car clusters.

• ffsec_face_events: feature vectors extracted from faces detected in the video.

• ffsec_face_objects: feature vectors extracted from face images uploaded to the card index.

• ffsec_face_clusters: centroids of face clusters.

• ffsec_user_face: feature vectors extracted from the FindFace Multi users’ photos for face-based authentication.
