FlexTally is a tally lamp system that consists of one station unit connected to the video switcher and four lamps attached to each camera. One station unit can have up to eight lamps connected (sold separately). When shooting with multiple cameras, such as when recording live programs or live streaming, each FlexTally lamp automatically lights up according to the video switcher’s switching operations, helping the performer to recognize which camera is being used.
