There are also USB-C and DC inputs on both the TX and RX units. So you could have an HDMI source coming in and an SDI source going out on the TX unit for example. The RX has an SDI Out and an HDMI Out.īoth the RX and TX units have cross-conversion. The MARS 4K comes with the following items:īoth the MARS 4K TX and RX units feature SDI and HDMI ports. I personally think that the MARS 4K would be more at home on small to mid-sized digital cinema cameras as opposed to mirrorless hybrids, although you could use it on some of the larger-sized mirrorless hybrids, or something like a Canon C70. This weight and size may not make them overly suitable for small-sized mirrorless hybrids. I would say that they are around a similar size to other comparable SDI/HDMI systems. The TX and RX are not tiny, nor are they too big. The MARS 4K RX and TX both weigh 223g / 7.86oz without the antennas. Overall I think most people will be more than happy with the way it has been constructed. The On/Off switch is reasonably solid and tactile, as is the little joystick you use to navigate and make changes in the menu.

The SDI connectors are slightly recessed, but the HDMI isn’t. According to Hollyland, the Mars 4K features superior corrosion and wear resistance for outstanding durability. The exterior casing is robust and I wouldn’t think it is likely to break if you dropped it. I have reviewed a lot of wireless video systems over the years, and the build quality of even the most budget-friendly options has continued to improve. With a large array of ‘affordable’ wireless video transmission systems now flooding the market, Hollyland decided to make something that was a little different from the competition.Īs I already mentioned, the whole concept behind the MARS 4K was to offer uses an affordable, high-quality wireless video system that could send and receive UHD images.
