Hollyland Mars 400S Pro II

The Hollyland Mars 400S Pro II is a professional wireless video transmission system that sends a clean, real-time video feed from your camera to monitors, phones and tablets without cables. Built for filmmakers, directors and video crews, it lets everyone on set see exactly what the camera sees, instantly and reliably.

On a shoot, this transforms how you work. The transmitter and receiver send crisp 1080p video up to around 150 metres with very low latency, so directors, clients and focus pullers can monitor the shot in real time. It supports both SDI and HDMI connections for flexible camera and monitor pairing, and a free app lets multiple crew members watch on their own devices at once.

It proves invaluable across professional productions. Directors monitor framing and performance from a comfortable distance, clients review shots live on a tablet, and gimbal operators keep an eye on the feed while moving freely. Compact and quick to set up, it fits neatly onto any rig without adding bulk.

For any serious video production, the Mars 400S Pro II removes the limits of cables and makes collaborative, professional monitoring effortless. It keeps the whole team on the same page in real time, helping everyone nail the shot together and streamlining the entire filmmaking workflow.
