Hollyland announced the new

. This is the company's follow-up action

.

The redesigned body should simplify the system when it is installed on the camera. When I first saw the design, it reminded me of the old Ricoh WG-60 waterproof digital camera.

I personally don't like these appearances. Ironically, the Mars 400S Pro looks more productive than the producer Mars 400S.

The biggest difference between Mars 400S Pro and Mars 400S is appearance. Nothing has changed. Both TX units have SDI and HDMI inputs, and both TX units have SDI and HDMI outputs.

The Mars 400S Pro TX and RX units weigh 206 grams (0.5 pounds), which is actually slightly heavier than the Mars 400S RX and TX units.

In terms of physical dimensions, the dimensions of the Mars 400S Pro RX and TX units are 4.3 x 2.8 x 1.32 inches / 11 x 7.2 x 3.35 cm. Mars 400S RX and TX are 4.41 x 2.56 x 0.94 inches / 11.2 x 6.5 x 2.4 cm

The original 400S and 400s Pro have the same claimed range when using RX and TX units, with a maximum range of 400', while when using TX and Hollyview Wi-Fi apps, the maximum range is 300'.

The delay time of 400S Pro is said to be 80 milliseconds. The sender can send at most one receiver and two applications at the same time, or send a total of four applications without the receiver. Through SDI or HDMI input, it can output up to 1080p60. This is exactly the same as Mars 400S.

In addition to the redesigned shell, compared with the original Mars 400S, there is indeed no obvious improvement.

Using the Hollyview app for iOS or Android, you can monitor the video transmission through a Wi-Fi connection, or you can use a USB Type-C adapter to monitor the real-time stream directly from the receiver through the computer. The app also allows you to install optional channel scanning firmware to easily find the strongest transmission signal. The sender can send at most one receiver and two applications at the same time, or send a total of four applications without the receiver.

The 400S PRO TX and RX have bright OLED displays for configuration; integrated hot shoe adapters with 1/4" -20 mounting threads for different mounting options.

You can use the USB Type-C power supply, the included lock-type DC power adapter to power each unit, or you can use a single-use L series battery with integrated battery board.

The retail price of Hollyland Mars 400S Pro is

, Which is $80 higher than the current price of Mars 400S on B&H ($569).
