Wireless 4K transmission for a professional video chain

Hollyland Mars 4K is a standalone on-camera transmitter with HDMI and 3G-SDI. It carries video up to 4K30 over 150 m line of sight while combining low latency with a clear colour display.

4K30 transmission at about 0.06 seconds

The dual-core codec works at 8–20 Mbps and preserves detail for monitoring and production control. HDMI supports 4K UHD up to 30 fps, while 3G-SDI extends compatibility with professional equipment.

Smart selection of a cleaner channel

Mars 4K scans available channels at startup and selects a more suitable frequency. The colour LCD reports interference and link status, allowing adjustments directly on set without another device.

Video for monitor, video village, and mobile viewing

The transmitter can work with two receivers, four mobile devices, or one receiver plus two phones or tablets in the HollyView app. One link can therefore serve the camera operator and additional crew members.

The exact configuration for its role

The standalone TX accepts HDMI or SDI from the camera and sends it to receivers or the HollyView app. Power can come from an NP-F battery, 6–16 V DC, or 5 V / 2.5 A USB-C.
