Smart channel scan

At startup, the Mars 400S Pro II automatically selects the best frequency channels. Manual channel scanning can be done using the receiver or the HollyView App, which provides a visual representation of signal interference levels on each frequency. The app allows you to install optional channel scanning firmware so you can easily find the strongest transmission signals.

Monitoring on up to 4 devices

The Mars 400S Pro II provides flexible solutions to meet monitoring needs, including team collaboration, multi-team monitoring, and multi-member collaboration. Using the Hollyview app for iOS or Android, you can watch the video transmission in real time over a Wi-Fi connection, as well as stream live from the receiver directly through your computer using a USB-C adapter. The transmitter can broadcast to up to one receiver and two apps simultaneously, or to a total of four apps without the receiver.

Flexible fan control

Each Mars 400S Pro II is equipped with a three-speed fan (Auto, Low Speed, Off). Thanks to the intelligent cooling design, the device performs optimally in different usage scenarios by lowering the device temperature and ensuring stable signal transmission.
