The Hollyland Mars 400S PRO SDI/HDMI Wireless Video Transmission System adds up to 1080p60 wireless video transmission to your gimbal, mirrorless, or DSLR camera rig.

The transmitter has HDMI and SDI inputs, while the receiver has SDI and HDMI outputs. With line-of-sight transmission up to 120m to the receiver and up to 90m to the Hollyview Wi-Fi app, it has an extraordinarily low 0.08-second latency. The system features two external antennas on the transmitter and two on the receiver for a strong line-of-sight signal, with one spare antenna included.

The Hollyland Mars 400S PRO SDI/HDMI Wireless Video Transmission System allows you to monitor your video transmission in real-time via a Wi-Fi connection using the Hollyview app for iOS or Android, as well as a live stream directly from the receiver via your computer using a USB Type-C adapter. You can also install optional channel scanning firmware through the app, which allows you to quickly locate the strongest transmission signals.

The transmitter can send data to up to two receivers and two apps at the same time, or a total of four apps without the receiver. It has a redesigned body that makes it a low-profile addition to your rig, and it has multiple fan modes to keep it cool or quiet while you shoot.

The 400S PRO transmitter and receiver are small in size and come with a bright OLED display for configuration as well as an integrated shoe adapter with a 1/4"-20 mounting thread for a variety of mounting options. Each unit can be powered by a USB Type-C port, the included locking DC power adapter, or an L-series type battery connected to the integrated battery plate.
