Product Description
Hollyland HL-Mars 4K Wireless Video Transmission System
The new Hollyland Mars 4K wireless video transmission system is capable of a 450ft (150m) LOS range and 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.
*The Mars 4K also supports FHD and HD formats at varying frame rates–24p, 30p, and 60p.
450ft (150m) LOS Range and 0.06s Ultra-low Latency
The Mars 4K achieves an incredible LOS range of 450ft (150m) and ultra-low latency of 0.06s. Its upgraded dual-core codec chip is capable of a data rate ranging from 8 Mbps to 20 Mbps, with 12 Mbps as the default.* The LOS range of 450ft (150m) is based on interference-free laboratory measurements.
* The latency of 0.06s is based on test data when 1080p60 signals are transmitted in a laboratory.
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
Operational Efficient Design Form Factor
The Mars 4K is featured with 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-Styled Button
The Mars 4K features a color LCD with a user-friendly UI design that enables quick configurations and status checks. Its uniquely designed rocker-styled button greatly improves the operational setup experience.
Multiple Power Supply Options
The Mars 4K supports a wide range of DC power options–6V to 16V, NP-F batteries, and USB Type-C chargers.
