Abstract: Systems and methods for communicating using both radio frequency (RF) communication and light communication (LC) are disclosed. An example device comprises radio frequency communication circuitry, a light communication transmitter; a light communication receiver; a processor for controlling the device according to executable code; and memory for storing data and executable code, wherein the executable code comprises instructions for causing the processor to establish RF communication with an RF access point using the RF communication circuitry; and to establish LC communication with an LC access point using the LC transmitter, the LC receiver, or both.

Abstract: Video communications of residents of a controlled-environment facility are monitored to detect instances of non-verbal communications within the video, such as the display of written messages and hand signals. Residents may participate in live video visitation sessions with non-residents. Video recordings are generated for each video feed of the live video visitation. During the live video visitation, indications of non-verbal communications displayed in the live video are detected. If indications of non-verbal communications are detected in the live video, the recorded video is annotated to specify the locations of the detected indications in the recording. Upon completion of the video visitation session, post-processing of the recorded video detects additional indications of displayed non-verbal communication. The additional indications may be detected at proximal locations to the annotations and may be detected based on sampling frames of the recording to detect changes in the color balance indicating the display of a message surface.
