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

The Hollyland Mars 400S Pro 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 allows you to transmit video wirelessly from a camera to a monitor, making your shooting setup cleaner and more flexible.

This system is ideal for film production, interviews, weddings, church livestreaming, YouTube production, corporate videos, documentaries, events and studio monitoring. It helps remove long HDMI or SDI cables from your setup while still giving your team a clear live video feed.

Professional SDI and HDMI Connection

The Hollyland Mars 400S Pro supports both SDI and HDMI connections. The transmitter has HDMI and SDI input, while the receiver has HDMI and SDI output. This makes it useful for DSLR cameras, mirrorless cameras, cinema cameras, professional camcorders and production monitors. Hollyland also notes that the receiver can output through SDI and HDMI at the same time.

Clear 1080p60 Wireless Video

The system supports video transmission up to 1080p 60fps, giving production teams a clean Full HD monitoring signal. It uses a 12Mbps data rate, helping preserve detail during wireless monitoring. This makes it suitable for directors, focus pullers, livestream operators and clients who need to view the camera feed during production.

Long Range and Low Latency

The Hollyland Mars 400S Pro wireless video system offers up to 400ft / 120m line-of-sight transmission range. It also has 0.1s low latency, helping the video feed stay responsive during live monitoring.

This is useful for event coverage, outdoor shoots, studio work and moving camera setups where the monitor needs to stay away from the camera.

Mobile App Monitoring

The Mars 400S Pro also supports monitoring on mobile phones or tablets through the HollyView app. This allows crew members to view the camera feed without needing a separate monitor. Hollyland states that up to 4 mobile phones or tablets can be used for monitoring at the same time.

The app also provides useful monitoring tools such as frame marking, zooming and brightness histogram, making it helpful for small crews and mobile productions.

Flexible Power Options

The Hollyland Mars 400S Pro supports multiple power options. It can be powered using an NP-F battery, power bank, USB-C charger or DC adapter. This gives creators more flexibility when shooting in studios, events or outdoor locations.
