The Hollyland Wireless Tally System (4 Tally Lights) is a wireless tally kit for multi-camera productions, letting camera operators and presenters see which camera is live or in preview without running tally cables. The kit includes a Tally Station base with two antennas and four battery-powered Tally Lights that mount on cameras. The station connects to switchers from brands such as Blackmagic Design, Roland, Datavideo, Panasonic and Sony, as well as vMix, and has a sequence-learning function to simplify setup. It uses 2.4 GHz LoRa transmission with adaptive frequency hopping, reaching up to 800 m line of sight with under 150 ms delay, and supports up to 16 tally channels. Each light runs over 8 hours on a swappable Li-ion 700 battery pack that is also compatible with Hollyland Solidcom C1 intercom systems. A tally light measures 77.8 x 50.5 x 37.4 mm and weighs about 85 g. In the box: Tally Station, four tally lights, hard-shell case, DC power adapter, two antennas, 4-slot charging base, four Li-ion batteries, USB-A to USB-C cable, number stickers and documentation.
