The Hollyland Wireless Tally System with 8 tally lights (WTS-8TL) adds wireless on-air indication to multi-camera productions, so presenters and camera operators can see which camera is live without running tally cables. The Tally Station connects to a vision switcher through DB25 or RJ45 tally ports or USB-C, and learns the switcher's tally sequence; the DB25 port supports up to 12 channels of dual-colour tally and the RJ45 port up to 16 channels. Adaptive frequency hopping avoids interference in busy RF environments, and line-of-sight range is up to 800 m, suiting churches, studios, sports and outside broadcasts. Each tally light is very light at 98.5 g with its battery, and a single detachable Li-ion 700 battery lasts over 8 hours. The 8-light kit includes the Tally Station, 8 tally lights, 8 Li-ion 700 batteries, an 8-slot charging base, two antennas, two DC power adapters, a USB-A to USB-C cable, number stickers and a hard-shell carry case. Check compatibility with your specific switcher model on Hollyland's list before ordering.
