Hollyland PYRO 4K Set 1:2 (TX+RX+Pyro 7Monitor RX) includes a Pyro S transmitter on camera, the Pyro7 Monitor as directors monitor and an external receiver for applications such as a client monitor. We also offer additional receivers to expand the set. Furthermore, mobile devices can be used as monitors via the Hollyland app. Pyro S is a groundbreaking addition to Hollyland's Pyro range, redefining wireless video transmission. Pyro S supports HDMI and SDI input/output and can transmit to up to four receivers simultaneously. It offers a range of up to 400 meters with a minimal latency of just 50 ms. Pyro S employs advanced ADH technology (Auto-Dualband Hopping) to ensure reliable transmission and features selectable modes tailored to your real-world shooting needs. Lighter and more durable than traditional models, Pyro S's magnesium alloy casing makes it easier to transport and operate. It is ideal for multi-user monitoring in dynamic shooting scenarios such as film production, live events, and ENG/EFP applications.
