Core Strengths & Setup Features
-
Dual Interfaces (HDMI & SDI): The transmitter features an HDMI input and a 3G-SDI input. The receiver handles HDMI and 3G-SDI outputs. This allows for cross-conversion (e.g., inputting an HDMI signal from a mirrorless camera and outputting SDI to a production monitor).
-
Flexible Monitoring Ecosystem: You aren't limited to just a physical receiver box. The system supports several flexible monitoring configurations via the HollyView App (iOS/Android):
-
1 Receiver + up to 2 Mobile Devices (tablets/smartphones)
-
0 Receivers + up to 4 Mobile Devices simultaneously
-
-
Smart Channel Selection: Upon startup, it performs an automatic frequency scan to identify and lock onto the cleanest, interference-free channel available.
-
On-Board UI: A small color LCD screen with a rocker-style joystick menu button replaces typical cryptic dip-switches, giving quick readouts of your signal strength, power state, and video format.
Power Flexibility: One of the best design aspects is its tri-power capability. You can run the units using Sony NP-F (L-series) batteries, a USB-C power source (5V/2.5A), or standard 6V–16V DC adapters.
