Hollyland Mars 300 Wireless Video Transmission System

The Hollyland Mars 300 is a wireless video transmission system designed for filmmakers, videographers, camera operators, directors, livestream teams and production crews. It allows you to send HDMI video wirelessly from a camera to a monitor, making it useful for film shoots, interviews, events, church media, YouTube production and professional video monitoring.

This system includes a transmitter and receiver, helping remove the need for long HDMI cables between the camera and monitor. It is a practical option when the director, producer or focus puller needs to view the camera feed from a distance.

Wireless HDMI Video Monitoring

The Hollyland Mars 300 supports wireless HDMI transmission with up to 300ft line-of-sight range. It supports video signals up to 1080p60, making it suitable for Full HD monitoring during video production.

This makes it useful for camera crews who need a cleaner and more flexible setup on set. Instead of running long cables across the floor, the Mars 300 sends the video feed wirelessly to a compatible monitor.

Low-Latency Performance

The system is designed for low-latency video monitoring. Published specifications list the transmission latency at less than 0.1 seconds, which helps give a more responsive viewing experience during shoots.

This is helpful for directors, camera assistants and clients who need to follow the shot in real time.

HDMI Input, Loop Out and Dual HDMI Output

The Hollyland Mars 300 video transmission system includes HDMI connection options for flexible production setups. The transmitter has HDMI input and HDMI loop out, allowing the camera signal to be sent wirelessly while also connecting to an on-camera monitor.

The receiver has dual HDMI outputs, allowing the received video signal to be sent to monitors, switchers or other compatible HDMI devices.

Good for Film, Events and Live Production

The Hollyland Mars 300 is useful for many video production setups. It can be used for weddings, events, interviews, church livestreaming, music videos, corporate videos, documentaries, YouTube shoots and studio recording.

It is especially helpful when the camera needs to move freely while the monitor remains in a fixed position.

Compact and Production-Friendly Design

Both the transmitter and receiver are compact and lightweight, making them easy to mount on cameras, monitors, cages or stands. The system supports Sony L-series style battery power and also has a DC input voltage range of 6–16V DC, giving production teams flexible powering options.
