It features an extremely low 70 ms latency and a high 12 Mb/s data rate with line-of-sight transmission up to 500′ to the receiver and to the Hollyview Wi-Fi app. For a strong line-of-sight signal, the system includes two external antennas on the transmitter and two on the receiver, and one is included as a spare.

Greater Range, Lower Latency

Crisp Clarity with High Data Rate

The system supports a high 12 Mb/s data rate, enabling high-definition video transmission and delivering clear, refined image quality with rich details.

Ultra-Low Latency

The Mars 400S Pro II raises the bar with a very low latency of just 70ms. It outperforms Mars 400S Pro by reducing latency by 30% and providing a stable signal transmission range of up to 500′. This ensures high-definition image quality and an immersive low-latency experience. It is also compatible with Mars 400S Pro, allowing them to be paired and used together.


Equipped with both SDI and HDMI interfaces, the Mars 400S Pro II provides enhanced device compatibility and convenient connections to various types of equipment. Whether it’s a DSLR or professional film camera, the Mars 400S Pro II can fulfill your connectivity requirements.

Smart Channel Scan

Upon startup, Mars 400S Pro II automatically selects the best frequency channels. Manual channel scanning can be conducted using the receiver or the HollyView App, providing a visual representation of signal interference levels at each frequency. The app allows you to install optional channel-scanning firmware, enabling you to easily find the strongest transmission signals.

Monitor on up to 4 Devices

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

Flexible Fan Control

Each Mars 400S Pro II unit is equipped with a three-speed fan adjustment feature (Auto, Low Speed, Off). Its intelligent cooling design allows it to perform optimally in various usage scenarios by reducing device temperature and ensuring stable signal transmission.
