Hollyland MARS 400S SDI/HDMI wireless video transmission system unboxing and first test. In this video, I go cover the unboxing, setup, short test, and why I invested in this wireless video transmission system.
Why I Bought The Hollyland MARS 400S
Long story short, I wanted to increase my ability to not needing my cameras located in one spot. With this system, I can operate a camera from a good distance. Projects I will be using this system will be for graduations, weddings, and events. The more I use this system, the more I will report on the experience. 
Is there anything you would like to know about my experiences with the Hollyland MARS 400S?
First Impressions
Upon opening and tinkering with the MARS 400S, it was super easy to setup. I used my Sony FS5 Mark II for the camera to link up with Ecamm and everything went well. Simply plug in, turn on, and everything synced up. There seems to be a slight delay, but I can adjust the audio and video syncing in Ecamm.
Other than the slight delay, everything looks great. I can’t wait to use this some more in the field.
