Hollyland Mars 300 PRO HDMI Wireless Video Transmitter/Receiver Set (Enhanced)

The Hollyland Mars 300 PRO HDMI Wireless Video Transmitter/Receiver Set (Enhanced Edition) is a compact, HDMI-only wireless video system designed for mirrorless and DSLR camera configurations.

The defining feature of the Enhanced Edition is the addition of removable, external "bullet" antennas on the transmitter module. While the standard model utilizes internal antennas on both ends, the Enhanced transmitter's external antennas provide superior signal propagation, stronger penetration through obstacles, and reduced dropouts in high-congestion environments like crowded convention centers or busy production sets.

Core Hardware & Signal Routing Strengths

• HDMI Loopout Monitoring Architecture: The transmitter features an intuitive dual-port array. Rather than ingesting two video feeds, it acts as a high-fidelity splitter: the HDMI Input captures your raw camera signal, while the HDMI Loopout sends that exact feed directly back out to an on-camera operator monitor or EVF without requiring standalone splitter hardware.

• Dual HDMI Outputs on Receiver: The receiver module provides two independent HDMI outputs. This allows you to simultaneously route the wireless video signal into two separate devices, such as a client monitor and a director's cage or a live streaming production switcher.

• 300ft Robust Reception Footprint: Transmits uncompressed HD video cleanly up to a 300-foot (90-meter) Line-of-Sight (LOS) operational radius over a secure 5 GHz digital frequency band.

• Side-Mounted OLED Telemetry Screen: Replaces legacy hardware dip-switches with a bright, high-contrast digital display matrix. Managed via a single clickable thumbwheel, it provides real-time information regarding channel frequency selection, active input format resolution, and current battery cell voltage.

Versatile Monitoring & App Integration

The Mars 300 PRO Enhanced kit effortlessly balances dedicated hardware configurations with mobile monitoring environments. Through the HollyView App (iOS/Android), you can split your real-time video distribution across three distinct field paths:

Dual Power Interface Architecture

To seamlessly adapt to shifting location variables, both the transmitter and receiver modules feature dual input power channels:

1. Sony NP-F Battery Plates: Integrates standard Sony L-Series slots (such as NP-F550, F750, or F970) directly on the rear face for total, untethered wireless mobility.

2. 5V/2A USB-C Power Interface: Allows both devices to be continuously driven by common portable smartphone power banks, USB multi-device bricks, or camera rig power distribution blocks.

💡 Smart Frequency Channel Scan: When troubleshooting signal dropouts on a busy set, you don't have to guess which frequency is clear. Clicking the thumbwheel button on the receiver pulls up an internal spectrum scanner that maps localized RF noise and recommends the absolute cleanest channel available to ensure a stable, artifact-free feed.
