QLHS: Revolutionizing Court and Interview Room AV Control

We are thrilled to introduce QLHS: the Liberty Recording Plugin for Q-SYS that seamlessly connects Liberty Court Recorder (LCR) and Liberty Interview Recorder (LIR) to Q-SYS Designer. This new plugin enables effortless real-time control and monitoring of Liberty recorders, unlocking new possibilities for courtrooms, interview rooms, and high-security recording environments.

By leveraging Liberty Helper Service (LHS)—our TCP-based communication bridge—QLHS brings flexible, scalable recording control directly to Q-SYS users, without overcomplicating AV workflows.

Why Q-SYS?

For those unfamiliar, Q-SYS is an industry-leading audio, video, and control (AV&C) platform from QSC. It is widely used in courtrooms, conference centers, legislative chambers, and corporate AV deployments because of its flexibility, scalability, and reliability.

Unlike traditional AV systems that rely on hardware-based DSPs and dedicated control processors, Q-SYS is a software-based platform that runs on standard IT infrastructure, making it:

✅ Highly customizable
Design your own user control interfaces (UCIs) tailored to any application.

✅ Scalable for any room size
From single-room setups to multi-courtroom deployments with centralized AV control.

✅ Network-based
Uses standard IP networking, eliminating complex wiring or proprietary hardware.

✅ Built for automation
Integrate cameras, microphones, lighting, and recording into a single workflow.

With Q-SYS, courts and interview rooms can simplify their AV ecosystems while maintaining powerful automation and control. And now, with QLHS, users can fully integrate court and interview room recording into their Q-SYS AV workflows—all within the same unified interface.

How QLHS Solves Modern Courtroom Challenges

🔹 Bench & Clerk Station Control
Judges can have a minimalistic Start/Stop interface at their bench, while clerks have full recording control at a nearby workstation or tablet.

🔹 Scalable UCI Integration
The plugin’s controls can be reshaped and mapped to any Q-SYS-style user control interface (UCI), allowing AV designers to create interfaces custom-tailored to each courtroom's needs.

🔹 In-Room Recording Time Display
The plugin can display real-time elapsed recording time in the room, helping attorneys and litigants take accurate notes on key moments (modernizing the old courtroom clocks from the 1980s).

🔹 Future-Proofing Court AV Systems
Both Q-SYS and Liberty software can be deployed as a centralized platform so that courtrooms of any size can implement smart, scalable recording solutions without adding unnecessary complexity.

Bringing Smart Automation to Interview Rooms

Interview rooms often rely on outdated, manual controls (light switches, push-button panels, or multiple devices operating independently). QLHS streamlines this by combining recording control with room automation.

Example: A Single Button to Control the Entire Room
A small 5-inch Q-SYS touch panel can replace multiple switches with a single button:

“Room On” — which can simultaneously

• Activate lights and A/V equipment

• Create a new recording file

• Start recording automatically

This level of automation ensures compliance, consistency, and ease of use—all while integrating seamlessly into existing AV infrastructure.

Liberty + Q-SYS: A True Two-Way Integration

If integrating Q-SYS control with Liberty through QLHS excites you, you’ll be thrilled to know that Liberty natively records Q-SYS IP streams over the network—no additional hardware or capture software required.

While Q-SYS video capture is already available, QLHS will soon be accessible through the Q-SYS Designer Asset Manager, streamlining integration like never before.
