In a typical setup for video recording, cameras are placed above, and in some cases to the side or below, the behavioral arena (Figure 1). The cameras send data to a computer and can be integrated with inputs from behavioral devices using custom-written programs using popular libraries such as OpenCV (Bradski, 2000), open-source data collection systems such as Bonsai (Lopes et al., 2015), or software included with many common commercial video capture boards (loopbio Motif).
