The Mars 4K also supports FHD and HD formats at varying frame rates such as 24, 30, and 60p. With H.264 encoding, it can achieve 8-20 Mb/s bit rate in HD/Balance/Speed scene mode.
Using the Hollyview app for iOS or Android, you can monitor your video transmission in real time via a Wi-Fi connection to your tablet or smartphone. The units also feature a built-in frequency scanner to select the clearest frequency for your transmission. The Mars 4K transmitter and receiver are compact in size, feature a bright touchscreen LCD display for configuration, and are built with a corrosion-resistant housing.
Long Range and Low Latency
The Mars 4K achieves a long line-of-sight range of 450′ and an ultralow latency of 0.06s. Its upgraded dual-core codec chip is capable of a 12 Mb/s default data transfer rate and it supports ranges from 8 to 20 Mb/s.
HDMI and SDI Interfaces
The Mars 4K supports HDMI and SDI input and output for expanded connectivity and compatibility. The SDI ports provide expanded frame rate flexibility for broadcast and production frame rate standards and compatibility through production and postproduction.
Broadcast and Production Frame Rate
The SDI and HDMI input interfaces of the transmitter both support 23.98/29.97/59.94 fps decimal point frame rate input. The receiver’s SDI and HDMI outputs can be output simultaneously. The 3G-SDI port supports broadcast and production standards frame rate output (23.98/29.97/59.94 fps) for professional equipment like video switches.
Form Factor
The Mars 4K features corrosion and wear resistance for durability. The design form factor optimizes operational functionality for fast configurations with wiggle-free, bullet-styled antennas attached.
Smart Channel Scanning
Channel assignment options allow for interference-free transmission. A stable connection is possible automatically upon startup. An intelligent channel scan helps determine which ones are occupied and selectable. The Mars 4K system is pre-pared upon delivery.
Multiple Power and Connectivity Options
The Mars 4K supports various DC power options: 6 to 16 VDC coax input, L-series/NP-F batteries, and USB-C chargers. The USB-C port on the Mars 4K device can be connected to a USB drive for upgrading.
Color Touchscreen LCD
The Mars 4K features a color touch LCD with a user-friendly UI design that enables quick configuration and status checks. Its gamepad-styled button dramatically improves the operational setup experience. Information such as channel, device signal, battery life, video format, application mode, and more are displayed on the screen.
