Flexible Monitoring Options

The Mars 4K transmitter is compatible with up to two receivers or four mobile devices with the app installed. Up to four mobile devices with the app installed allow a maximum of four parties (such as the director, producer, light control personnel, and audio personnel) on the site to monitor the shooting at the same time.

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.
