Hollyland Mars 400S Pro SDI/HDMI Wireless Transmission System

Awake to the Power

Get up to 1080p60 wireless video transmission on your gimbal stabilizer, mirrorless or DSLR camera rig with the lightweight Hollyland Mars 400S PRO SDI/HDMI Wireless Video Transmission System. The transmitter provides HDMI and SDI inputs and the receiver offers SDI and HDMI outputs. It features extremely low 0.1s latency with line-of-sight transmission up to 122m to the receiver and up to 91m to the HollyView Wi-Fi app. For a strong line-of-sight signal, the system includes two external antennas on the transmitter and two on the receiver, and one is included as a spare.

The redesigned body makes it a low-profile choice for your rig, and it features multiple fan modes to keep it cool or quiet when you are shooting.

Scan channels to find out which channels are occupied at the press of a single key. Select any interference-free channel at a glance and rest assured that you have a stable connection when transmitting. The optimum channel is intelligently (automatically) selected after startup and no manual selection is required. The app also allows you to install optional channel scanning firmware enabling you to easily find the strongest transmission signals. 

Using the Hollyview app for iOS or Android, you can monitor your video transmission in real-time via a Wi-Fi connection as well as live stream directly from the receiver via your computer using a USB Type-C adapter. The transmitter can simultaneously transmit to up to one receiver and two apps, or to a total of four apps without the receiver

Each unit can be powered using a USB Type-C source, the included locking DC power adapter, or by using a separately available L-series type battery using the integrated battery plate.
