Cerevo announces the global availability of “FlexTally”
A wireless tally lamp system, competitively priced and easy to set

Cerevo Inc., an Internet connected consumer electronics manufacturer headquartered in Tokyo, Japan, announces “FlexTally” that supports both wireless and wired connections will be available for pre-order from 1st December 2017 (EST) at the Cerevo Official Store for US$529.00, and will begin shipping in January 2018.

“FlexTally” is a competitively priced and easy to set up tally system for small & professional crews. Cerevo also makes available additional lamps for purchase separately for US$129.00.




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.

If you use FlexTally in combination with Cerevo’s live streaming video switcher LiveWedge, no advanced setup is required and users can easily complete installation without special knowledge of video equipment or network connections. The station unit can be connected to LiveWedge by simply connecting to the same Ethernet network as LiveWedge. It is also possible to connect directly to LiveWedge without going through a router.*1 In addition, FlexTally is compatible with other brands’ switchers*2 such as Blackmagic Design’s ATEM series, NewTek’s TriCaster series etc. as well as other switchers that support GPIO-capable connections.

Built-in batteries in the lamps eliminate the need for multiple power cables. They use the 433MHz wireless band*3 which is resistant to obstacles and interference from other wireless signals. The wired connection uses a standard RS-485 serial connection.
