Hollyland Mars 4K Wireless Video Transmission System Set

The Hollyland Mars 4K Wireless Video Transmission System is a wireless video transmitter and receiver kit designed for real-time monitoring on set. It supports 4K UHD video transmission up to 30p via HDMI and Full HD up to 1080p60 via HDMI or SDI, depending on configuration.

The system operates on a dual-band 2.4 GHz / 5 GHz wireless platform, automatically selecting the most stable channel to minimize interference. Transmission latency is low (approximately 0.06–0.1 seconds), making it suitable for director, focus puller, and client monitoring, though not intended for critical focus pulling.

The Mars 4K supports a line-of-sight transmission range of up to approximately 150 meters, depending on environment and interference. It allows one transmitter to multiple receivers and also supports simultaneous monitoring via dedicated mobile apps on iOS or Android devices.

Power options include NP-F battery plates, DC input, or USB-C power, providing flexibility for camera-mounted or stand-mounted use. The units feature compact aluminum housings with integrated cooling and standard mounting points for rig integration.
