Hollyland Mars 400S Pro II SDI/HDMI Wireless Video Transmission System

The Hollyland Mars 400S Pro II SDI/HDMI Wireless Video Transmission System is a professional wireless video transmission system designed for filmmakers, videographers, livestream teams, camera operators and production crews. It helps send video wirelessly from a camera to a monitor, making your setup cleaner, faster and easier to manage.

This system is ideal for film production, weddings, church livestreaming, interviews, events, YouTube production, corporate videos and studio monitoring. It is useful when the camera operator, director, producer or livestream team needs to view the camera feed without using long HDMI or SDI cables.

SDI and HDMI for Flexible Production

The Hollyland Mars 400S Pro II comes with both SDI and HDMI interfaces, making it suitable for DSLR cameras, mirrorless cameras, cinema cameras, professional camcorders, switchers and production monitors. Hollyland states that the Mars 400S Pro II is equipped with SDI + HDMI dual interfaces for wider device compatibility.

450ft Wireless Range and Low Latency

The system offers up to 450ft / 150m line-of-sight transmission range and low latency of 70ms in HD mode. This gives production teams a responsive monitoring experience for live shoots, interviews, events and moving camera setups. Hollyland notes that the 450ft range is based on interference-free laboratory measurements.

Clear 1080p60 Video Transmission

The Hollyland Mars 400S Pro II wireless video system supports Full HD video formats up to 1080p60 through HDMI and SDI. It also supports a 12Mbps data rate, helping deliver a clear and detailed monitoring feed for directors, focus pullers, livestream operators and production teams.

Monitoring on Multiple Devices

The Mars 400S Pro II supports flexible monitoring options. It can work with 1 transmitter and 2 receivers, 1 transmitter with 1 receiver and 2 app devices, or 1 transmitter with up to 4 app devices using the HollyView app. This is helpful for team collaboration when several people need to monitor the video feed at the same time.

Smart Channel Scan and Fan Control

The system includes Smart Channel Scan, which helps identify better frequency channels and reduce interference during production. It also has three fan modes: Auto, Low Speed and Off. This is useful when recording in quiet environments where fan noise needs to be minimized.
