The Hollyland Mars 4K SDI and HDMI Wireless Video Transmission System can operate up to 450 feet range in line-of-sight and offers ultra-low latency of 0.06s. The Mars 4K is designed to combine high performance and reliable quality at an affordable price.

4K UHD Video Transmission

The Mars 4K supports 4K UHD video transmission at 30fps for the discerning videographer looking for high-resolution production capability. It also supports FHD and HD formats at varying frame rates of 24p, 30p, and 60p.

450 Feet Line-of-Sight Range and 0.06s Ultra-Low Latency

The Mars 4K achieves an incredible line-of-sight range of 450 feet (based on interference-free laboratory measurements) and ultra-low latency of 0.06s. Its upgraded dual-core codec chip is capable of a 12 Mbps data transfer rate.

HDMI and SDI Dual Interfaces

The Mars 4K supports HDMI and SDI input and output for expanded connectivity and compatibility. The SDI provides expanded frame rate flexibility for both broadcast and production frame rate (decimal-point frame rate) standards and compatibility through production and postproduction.

Flexible Monitoring Options

The Mars 4K transmitter is compatible with up to two receivers or four mobile devices with the app installed. Up to four mobile devices with the installed app allow a maximum of four parties (such as the director, producer, light control personnel, and audio personnel) on the site to monitor the shooting at the same time.

Operational Efficient Design Form Factor

The Mars 4K features superior corrosion and wear resistance for outstanding durability. With disassembly-free, bullet-styled antennas attached, the well-thought-out design form factor optimizes operational functionality for fast configurations.

Smart Channel Scan and Selection

Channel assignment options allow for interference-free transmission. A stable connection is possible automatically upon startup. Smart channel scan helps determine which ones are occupied and selectable.

Color LCD with an Exclusive Rocker-Style Button

The Mars 4K features a color LCD with a user-friendly UI design that enables quick configurations and status checks. Its uniquely designed gamepad-styled button greatly improves the operational setup experience.

Multiple Power Supply Options
