The Hollyland Mars 4K is a wireless video transmission system designed for professional video production, offering robust and reliable performance for various shooting scenarios. This quick guide provides an overview of its functions, features, and basic setup, enabling users to quickly integrate it into their workflow.
Function Description
The Mars 4K system facilitates wireless transmission of high-quality video signals, supporting resolutions up to 4K at 30 frames per second. It comprises a transmitter and a receiver, working in tandem to send video from a camera to a monitor or other receiving devices. The system is designed to minimize latency, ensuring that the transmitted video is nearly in real-time, which is crucial for monitoring and critical focus pulling on set. It supports both HDMI and SDI inputs and outputs, offering versatility for compatibility with a wide range of professional cameras and monitors. The transmitter takes video input from a camera via HDMI or SDI, encodes it, and sends it wirelessly. The receiver then decodes the signal and outputs it via HDMI or SDI to a monitor. This setup eliminates the need for long, cumbersome cables, providing greater freedom of movement and flexibility on set. The system also supports monitoring via a mobile app, allowing additional team members to view the feed on their smartphones or tablets.
Usage Features
The Mars 4K system is engineered for ease of use and efficiency in demanding production environments.
- High-Resolution Video Transmission: The system supports 4K 30fps HDMI input and output, ensuring that high-quality video can be transmitted without compromise. This is particularly beneficial for productions requiring detailed monitoring and precise visual feedback.
- Versatile Connectivity: Both the transmitter and receiver feature multiple input/output options. The transmitter includes SDI and HDMI inputs, while the receiver offers SDI and HDMI outputs. This broad compatibility allows the system to integrate seamlessly with various professional cameras, camcorders, and monitors, reducing the need for additional converters.
- Smart Channel Selection: Upon power-on, the Mars 4K intelligently selects the optimal wireless channel, minimizing interference and ensuring a stable connection. This automatic feature simplifies setup and helps maintain consistent video quality throughout a shoot. Users can also manually select channels using the rocker-styled button on the device.
- Low Latency: With a transmission latency of just 66ms, the Mars 4K provides near real-time video monitoring. This low latency is critical for applications such as focus pulling, camera operation, and director monitoring, where immediate visual feedback is essential for making timely adjustments.
- Extended Transmission Range: The system offers an impressive wireless transmission distance. For the receiver, it can reach up to 450ft (150m) in line-of-sight (LOS) conditions. When using the mobile app for monitoring, the range is 260ft (80m) (LOS). These ranges provide ample flexibility for various shooting locations, from small studios to large outdoor sets.
- Multiple Power Supply Options: The Mars 4K can be powered in several ways, enhancing its adaptability on set. It supports DC power input, NP-F type batteries (compatible with NP-F970 and similar series), and USB-C power supply. This flexibility ensures continuous operation, even in environments where traditional power sources are limited.
- Color LCD Display: Both the transmitter and receiver are equipped with a color LCD display, providing clear and intuitive access to critical information such as signal strength, power supply status, USB connection, video format, channel display, device Wi-Fi ID, and application mode. This display allows users to quickly monitor the system's status and make necessary adjustments.
- Intuitive Menu Options: The device features a menu button that, when pressed and held for 3 seconds, allows users to access and change various settings. The rocker-styled button can be used to navigate through the menu options, making configuration straightforward.
- Mobile App Monitoring (HollyView): The Mars 4K integrates with the HollyView mobile app, allowing users to monitor the video feed on their smartphones or tablets. This feature provides additional monitoring points for crew members, such as directors, producers, or script supervisors, without requiring dedicated monitors. Connecting to the app is simple: users find the device's Wi-Fi ID ("HLD+DEVICE ID") on their mobile phone, enter the default password (12345678), and connect.
- Expansion Accessory Mounting Hole: The devices include an expansion accessory mounting hole, allowing for the attachment of additional accessories, further enhancing their utility and integration into existing camera rigs.
- Robust Design: The physical design of the units is compact and durable, suitable for the rigors of professional production. The inclusion of a cold shoe mount allows for easy attachment to cameras or other equipment.
Maintenance Features
While the manual primarily focuses on usage, some aspects touch upon maintenance and care.
- Antenna Installation: Proper installation of the antennas is crucial for optimal performance. Users are instructed to install the antennas as shown in the provided diagrams, ensuring a strong and stable wireless connection.
- Battery Management: The system supports NP-F batteries, and users are advised to install compatible batteries (e.g., NP-F970 or similar series). Monitoring the battery indicator on the LCD display helps in managing power and ensuring uninterrupted operation.
- Secure Mounting: The receiver can be installed on a stand using its 1/4 threaded hole, ensuring stable positioning during operation. The transmitter can be mounted on a camera via a cold shoe. Secure mounting prevents accidental damage and maintains optimal signal transmission.
- Cable Management: Users are instructed to connect the transmitter to the camera using appropriate HDMI or SDI cables. Proper cable management, including using self-locking DC adapters, helps prevent accidental disconnections and ensures reliable power and video input.
- Environmental Considerations: The manual includes safety precautions, advising users not to place the product near or inside heating devices to prevent overheating and potential battery explosion. This highlights the importance of operating the device within suitable environmental conditions.
- Accessory Usage: The guide emphasizes using original charging cases, cables, and batteries to avoid potential hazards such as electric shock, fire, or explosion. This underscores the importance of using approved accessories for safety and optimal device performance.
- Troubleshooting Guidance: Although not explicitly detailed as maintenance, the support section provides contact information for technical assistance, implying that users can seek help for any operational issues or problems encountered with the product. This includes a user group, social media channels, email support, and a website.
- FCC Compliance: The device complies with FCC regulations, and users are informed about measures to correct potential interference, such as reorienting antennas, increasing distance between equipment, or connecting to different power outlets. This information helps users maintain optimal signal integrity and resolve common interference issues.
In summary, the Hollyland Mars 4K is a high-performance, user-friendly wireless video transmission system designed to enhance flexibility and efficiency in professional video production, with features that prioritize signal quality, range, and ease of operation.
