Hollyland Mars 4K – 150m LOS and 0.06s Ultra-low Latency 4K UHD Wireless Video Transmitter
The Hollyland Mars 4K wireless video transmission system delivers 4K UHD video to on-set monitors with a 150m line-of-sight (LOS) range and an ultra-low latency of 0.06s. Designed to combine high performance and reliable quality at an affordable price, the Mars 4K targets filmmakers and production teams who need high-resolution transmission with dependable connectivity.
4K UHD video transmission and supported frame rates
The Mars 4K supports 4K UHD video transmission at 30 frames per second (30fps). It also handles FHD and HD formats across common production frame rates, including 24p, 30p, and 60p. This makes the unit suitable for high-resolution shoots while remaining compatible with standard broadcast and production workflows.
Range, latency and data throughput
The system achieves a 150m LOS transmission range and an ultra-low latency of 0.06s, enabling near real-time monitoring on set. An upgraded dual-core codec chip powers the Mars 4K and supports a 12 Mbps data transfer rate. Note that the 150m LOS figure is based on interference-free laboratory measurements.
HDMI & SDI dual interfaces for flexible connectivity
The Mars 4K offers both HDMI and SDI input and output. Use HDMI for compatibility with a wide range of cameras and monitors. Use SDI when you need expanded frame rate flexibility or decimal-point frame rate standards required in broadcast and production environments. These dual interfaces help ensure compatibility through production and postproduction workflows.
Flexible monitoring options for the whole crew
You can connect the Mars 4K transmitter to up to two dedicated receivers or allow up to four mobile devices to view the feed via the Hollyland app. Allowing four mobile devices to connect means key personnel—such as the director, producer, lighting technician, and audio engineer—can monitor the shoot simultaneously from their phones or tablets.
Operationally efficient design and durable construction
The Mars 4K features a design focused on field efficiency. It uses disassembly-free, bullet-styled antennas that stay attached for fast setups. The housing provides superior corrosion and wear resistance for outstanding durability, supporting repeated on-set use and rough handling.
Smart channel scan and automatic selection
Smart channel scan identifies occupied channels and suggests the best channel assignment for interference-free transmission. The Mars 4K can automatically establish a stable connection on startup, helping reduce setup time and minimizing the need for manual channel adjustments during a shoot.
Color LCD and exclusive rocker-style button for quick control
The unit includes a color LCD with a user-friendly UI that lets you check status and make quick configuration changes. An exclusive gamepad-styled rocker button simplifies navigation and speeds up operational setup, especially when working alone or on fast-moving shoots.
Multiple power supply options
The Mars 4K supports a wide range of DC power inputs from 6V to 16V. It also accepts NP-F batteries and can be powered by USB Type-C chargers, giving you flexible options for power on location or in the studio.
