The standard package of FlexTally contains one station unit that connects to a video switcher and four lamp units that are to be attached to each camera, each lamp illuminates automatically according to the switching operation. The Tally Lamp System can be used for recording or live streaming with multiple cameras. Without a professional broadcasting studio camera setup, on camera performers or presenters have no way to know which of the multiple cameras is active. Using a tally lamp system, an indicator lamp called a “tally lamp” is set near the lens of each camera and the tally lamp with a pilot lamp to show which camera is active.

Since its launch, FlexTally has been well received by professional and individual users around the world for its ease of use and simple operation.
