The Hollyland Mars 400S Pro II is a video radio link with SDI and HDMI interfaces and a transmission range of up to 150 metres with a direct line of sight. The latency time is only 70 milliseconds. The Mars 400S Pro II offers stable and reliable signal transmission of high-quality HD video, supporting data rates of up to 12 Mbps.

In addition, monitoring of up to four devices is possible in the following constellations: the transmitter can either transmit to up to two receivers or it can transmit to one receiver and two mobile devices or to up to four mobile devices without a connected receiver. This provides a flexible solution for individual collaboration between several employees or crew members.

The video wireless link is also characterised by an intelligent fan design with three different modes to ensure optimum performance for different applications. Depending on the scenario, the noise level is adjusted as follows: an automatic adjustment of the fan speed depending on the temperature, a low fan speed for a low noise level or switching off the cooling system in absolute silence.

The Mars 400S Pro II is connected to the desired device via the integrated accessory shoe with 1/4" thread, so that no further installation steps are required.
