Incredible Range, Low Latency. This Hollyland Mars 400S PRO II SDI/HDMI Wireless Video System provides a single transmitter and a single receiver to transmit 1080p60 wireless video to your dedicated rig from up to 500 feet away. An ultra-low latency of 70ms delivers minimal delay in transmission, outperforming the OG Mars 400S Pro by 30%. The Pro II system supports a 12 Mb/s data rate that delivers rich, crisp HD video transmission across the spectrum.

SDI and HDMI. Both components of this system offer SDI and HDMI interfaces, with the transmitter offering inputs, and the receiver offering outputs. This allows the system conveniently connect to a wide range of devices, whether you’re rocking with a DSLR, a professional film camera, or gimbal rig.

Smart Channel Scan and Monitoring. As soon as this system starts up, smart channel scanning is activated and promptly finds the best frequency channels to work through. Manual scanning can be done using the receiver or the good ole HollyView App, which will give you a good look at signal interference at each frequency. Additionally, the app has a downloadable channel-scanning firmware so you’re always on top of the strongest transmission signals. As far as monitoring needs go, the Mars II Pro offers flexible solutions to multi-person viewing. Using the aforementioned HollyView App, you can transmit to one receiver and monitor from up to two app-compatible devices with just one transmitter, or up to four app-compatible devices without a receiver.

Keepin’ It Cool. Mounting this system to your rig is a breeze thanks to the simple shoe adapter with a 1/4"-20 screw. When the cameras are rolling and the system’s putting in work, the intelligent three-speed cooling system keeps the devices working in proper order and ensures a safe device temperature.
