Hollyland Mars 300 Pro Wireless Video Transmitter/Receiver Set

Wireless HDMI Video Transmission for Camera Monitoring

This wireless HDMI video transmitter and receiver set is designed to send high-definition video from a camera to monitors or mobile devices without running cables. It supports wireless transmission of video signals up to 1080p at 60 frames per second, making it well suited for mirrorless cameras, DSLR rigs, gimbal setups, and compact production workflows. The system allows crews to monitor video remotely while keeping camera setups lightweight and mobile.

Long Range Line of Sight Wireless Performance

The system provides reliable line-of-sight transmission up to 400 feet when sending video to the receiver and up to 300 feet when streaming to a compatible mobile app. This range supports flexible camera placement across film sets, event spaces, studios, and interview locations. Wireless performance is optimized for real-time monitoring, allowing operators and directors to view the image without noticeable delay.

HDMI Input Loop Output and Dual Receiver Outputs

The transmitter includes an HDMI input along with an HDMI loop output, allowing an on-camera monitor to remain connected while the video feed is sent wirelessly. The receiver features two HDMI outputs, making it possible to send the signal to multiple displays or recording devices at the same time. This configuration supports efficient monitoring for multi-person crews.

Mobile App Monitoring on iOS and Android Devices

Real-time video monitoring is available through a compatible mobile app on iOS and Android devices. The system can transmit to one receiver and two mobile devices simultaneously, or to up to three mobile devices without a receiver. This allows directors, focus pullers, and clients to monitor the live image using smartphones or tablets without additional hardware.

Compact Units with OLED Displays for Easy Setup

Both the transmitter and receiver feature compact housings with integrated OLED displays. These screens provide quick access to system information such as channel settings, signal strength, and power status. The small form factor makes the units easy to mount on camera rigs, cages, or stabilizers without adding unnecessary weight.

Flexible Power and Mounting Options for Production Use

Each unit can be powered through a USB Type-C connection or by optional L-series batteries using the integrated battery plates. Standard 1/4"-20 mounting threads allow secure attachment to camera rigs, cages, or mounting arms. Included accessories such as a shoe mount and expansion plate support a wide range of production configurations.
