The Hollyland MARS400S Pro is a state-of-the-art HD image transmission system from cameras/devices with SDI/HDMI output to monitors/devices with SDI/HDMI input as well as to iOS devices, Androids, smartphones, and tablets. It stands out for its particularly small and practical size, its excellent quality metal construction, and its ability to be powered (transmitter and receiver) by common Sony L-type batteries (F770/F970). Additionally, it features an OLED screen for comfortable device status overview.

It transmits HD images with high reliability and low latency (<0.08 sec) over a distance of 100+ meters. Special algorithms during image transmission ensure that it is transferred with minimal noise.
