Hollyland Mars 4K 450ft 4K UHD wireless video transmission

Hollyland Mars 4K — 450ft 4K UHD wireless video transmission with 0.06s ultra-low latency

The Hollyland Mars 4K delivers 4K UHD wireless video transmission designed for filmmakers and production crews who need high-resolution monitoring and low delay. It combines multi-format video support, flexible connectivity, and multiple power options into a compact transmitter/receiver system that aims to offer reliable performance at an accessible price point.

4K UHD video support and frame rates

The Mars 4K transmits 4K UHD video at 30fps for high-resolution production workflows. In addition, it supports FHD and HD formats across common production frame rates. Specifically, the system supports 24p, 30p and 60p frame rates to match a variety of shooting standards and styles.

Range, latency and data throughput

The Mars 4K achieves a line-of-sight (LOS) range of 150 m and an ultra-low latency of 0.06 seconds. It uses an upgraded dual-core codec chip capable of a 12 Mbps data transfer rate, which contributes to its low-latency performance and stable video feed.

*The LOS range of 150 m is based on interference-free laboratory measurements.

HDMI and SDI dual interfaces

The system provides both HDMI and SDI input and output for broad compatibility with cameras, monitors and recorders. SDI support adds expanded frame rate flexibility and compatibility with broadcast and production decimal-point frame rate standards, which helps integrate the Mars 4K into professional production and postproduction workflows.

Flexible monitoring options for crews

The Mars 4K supports multiple simultaneous monitoring configurations. You can use up to two dedicated receivers or connect up to four mobile devices running the Hollyland app. This enables the director, producer, lighting or audio personnel to view the live feed at the same time, improving on-set collaboration.

Operational design and durability

The transmitter features superior corrosion and wear resistance for increased durability in production environments. Its disassembly-free, bullet-styled antennas stay attached for quick deployment, and the overall form factor focuses on operational efficiency for fast setups on set.

Smart channel management

Smart channel scan and selection streamline wireless setup by detecting occupied channels and choosing interference-free options. In addition, the Mars 4K can establish a stable connection automatically on startup when suitable channels are available, reducing configuration time before rolling camera.

Color LCD and rocker-style control

A color LCD with a user-friendly interface provides fast status checks and configuration. The unit uses a gamepad-styled rocker button to simplify menu navigation and improve the setup experience during shoots.

Multiple power supply options

• Supports a wide DC input range: 6V to 16V
• Accepts NP-F style batteries
• Can be powered via USB Type-C chargers

This variety of power options lets you adapt to different on-location power setups and battery workflows.
