Hollyland Mars 400S PRO SDI/HDMI Wireless Video Transmission System

The Hollyland Mars 400S PRO SDI/HDMI Wireless Video Transmission System allows you to add up to 1080p60 wireless video transmission to your gimbal, mirrorless, or DSLR camera rig. The transmitter provides HDMI and SDI inputs and the receiver offers SDI and HDMI outputs. It features extremely low 0.1s latency with line-of-sight transmission of up to 120m to the receiver and up to 91m 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.
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 Type-C adapter. The app also allows you to install optional channel-scanning firmware to find the strongest transmission signals easily. The transmitter can simultaneously transmit to up to one receiver and two apps, or to a total of four apps without the receiver. The redesigned body makes it a low-profile choice for your rig, and it features multiple fan modes to keep it cool or quiet when you are shooting.
The 400S PRO transmitter and receiver are compact in size, and feature a bright OLED display for configuration, and an integrated shoe adapter with a 1/4"-20 mounting thread for different mounting options. Each unit can be powered using a USB Type-C source, the included locking DC power adapter, or by using a separately available L-series type battery using the integrated battery plate.
 

 Wireless Video Transmission to the Next Level
With a brand-new design, 12Mbps ultra-high data rate, SDI & HDMI dual ports and other features built for professional filmmaking the Hollyland Mars 400S PRO brings video transmission to the next level, empowering filmmakers, crews, and content creators everywhere.
12Mbps Data RateAt an updated data rate of 12Mbps, the system can easily handle video transmission at 1080p60, ensuring the quality of live broadcasts and preserving the details of every picture.
120m Transmission Distance with 0.1s LatencyNumbers that matter. With transmission distances up to 120m and latency less than 0.1s the transmission stays uninterrupted even if the studio is as big as a soccer field.

SDI & HDMI Dual Ports
With the classic SDI+HDMI dual ports, you can choose either port for input or output, and there is no need to use the same type of ports for both input and output. Whether it is a DSLR, mirrorless or professional camera, you can connect it to the input. You can send output with both the SDI and HDMI ports at the same time
1x Transmitter x 2 Receivers for Efficient Monitoring Made Easy
One transmitter can work with up to two receivers. So, the system allows two parties (director, investor, etc.) on the set to simultaneously monitor the shots with high picture quality at a 12mbps data rate and ultra-low latency.

3 Cooling Modes
Three different cooling modes are available: Auto, Low and Off. The higher the fan speed, the lower the temperature of the device casing. While the fan produces very low noise at a maximum noise level of 55dB you can select the best mode for your shooting environment.

Auto mode | The fan speed is automatically adjusted according to the temperature of the device to ensure rapid heat dissipation.
Low speed mode | The fan speed is reduced to a minimum to reduce fan noise while keeping temperatures stable.
Off mode | This mode eliminates fan noise by turning the cooling off. Use this mode if you need an absolutely quiet environment.

Intelligent Channel Scan
Smart channel scan can be activated with a single key press. You can find out which channels are occupied at a quick glance and select an interference-free channel to use for the connection. Note: The optimum channel is automatically selected after startup and no manual selection is required.
Multiple Power Supply Options
The Mars 400S PRO can be supplied via a USB-C power bank, DC adapter or run of NP-F style batteries. The multiple powering options let you ensure a continuous power supply in all kinds of situations.

Easy Monitoring via Mobile Devices
The system supports monitoring with an app on a phone or tablet. The app acts like a monitor and provides 9 auxiliary functions such as brightness histogram, frame marking, and zooming. Any additional monitoring persons required temporarily can directly connect to the app without installation for more convenience and you can connect up to 4 phones or tablets for monitoring at the same time.
