Feature Limits

• Multiple Body Point Module (Live Tracking): Maximum four arenas per computer. In principle it is possible to track in more than four arenas, but it depends on the apparent size of the subjects in the video image (in pixels). Sample rate must be 25 samples/s or higher.

• Multiple Arena Module: Maximum 100 arenas. The number of arenas may be limited by other factors, for example the number of subjects in each arena and the tracking of multiple body points. Contact Noldus if you wish to work with more than 100 arenas.

• Social Interaction Module: Maximum 16 subjects per arena. If subjects are unmarked, there may be subject identity swaps.

• CognitionWall (Sylics): Four arenas, only center-point tracking; up to 72 h recording. In case of recordings longer than 24 h, we advise to restart the PC after each trial. A workstation is required.

• Behavior Recognition: One subject per arena; one arena (live tracking), up to four arenas (offline tracking). Requires the Multiple Body Point module. Camera must be overhead. Camera frame rate must be at least 25 fps with no missing frames. Cannot work together with Deep Learning-Based Tracking. The PC must be a workstation. See Behavior Recognition: Requirements.

• Deep Learning for Nose-Tail Base Tracking: One or two subjects per arena (up to four arenas). See Deep Learning: Requirements.
