Hollyland Mars 300 PRO HDMI Wireless Video Transmitter

The Hollyland Mars 300 PRO HDMI Wireless Video Transmitter comes with an HDMI loop out to meet the needs of monitoring shots near the camera.

Broader Coverage, Less Latency 

The 120m transmission distance supports a larger working range. The 0.1s ultra-low latency ensures instant transmission, allowing the cameraman to collaborate more efficiently with the director, lighting technician, etc. in the shooting or live-streaming team. 

One-for-All Thumbwheel Switch 

The function menu is operated by a thumbwheel switch. You can choose the desired function or channel by turning the thumbwheel switch. The thumbwheel switch is used to configure all settings, which effectively reduces the number of buttons on each device, making it more elegant and integrated. 

HDMI Port and Loop Out Support 

To allow you to connect more devices, the transmitter provides an HDMI port, which supports input. The HDMI port on the transmitter is a loop out, which can output video to a small monitor on the camera, and allow the cameraman to see the shots. 

All Key Info at a Glance 

The high-definition side OLED display clearly shows all necessary info including signal strength, remaining battery power, and channel. Whether the device is installed vertically or horizontally, the screen will face you, and you can see what is displayed without lowering the device.

Your Phone is Your Monitor 

You can monitor the shots with an app installed on your phone or tablet. The app provides additional functions including 3D LUTs, focus peaking, zebra, and zooming. By turning phones into monitors, multiple team members can collaborate on a cost.

Quick and Easy Firmware Upgrade Via App 

Once you have connected to the device using the mobile app, you can start the firmware upgrade by tapping a single button. It's so simple that even a newbie can easily complete the upgrade.
