Exceptional design

The redesigned chassis should make the system more streamlined when mounted on camera platforms. When I first saw the design, it reminded me of the old Ricoh WG-60 waterproof digital camera.

Personally, I'm not a fan of the way these look. Somewhat ironically, the Mars 400S Pro appears to be more consumer-friendly than the Mars 400S.


The difference between MARS 400S and MARS 400S PRO

The biggest difference between Mars 400S Pro and Mars 400S is the appearance. There aren't many changes. Both TX modules have SDI and HDMI inputs and both TX modules have SDI and HDMI outputs.

The Mars 400S Pro TX and RX units weigh 206g making them slightly heavier than the Mars 400S RX and TX units.

Hollyview app

With the Hollyview iOS or Android app, you can monitor video transmission over Wi-Fi connection. One of the most important features of the device is the live broadcast from the receiver via your computer using a USB Type-C adapter.

The app also lets you to install optional firmware to scan channels allowing you to easily find the strongest transmission signals. A transmitter can transmit simultaneously to up to one receiver and two applications, or a total of four applications on four phones without the receiver.
