Getting Started
PTZOptics Voice Tracking is an audio-driven camera automation system that uses a supported microphone to detect where sound is coming from in a room and automatically directs PTZOptics cameras to the active speaker. When paired with a video switcher, it can also trigger live camera cuts, creating a fully automated, operator-free production. To set up Voice Tracking, you will need to activate the license on your camera, connect a supported microphone, and configure the system to recognize which zones in the room correspond to which camera presets.
Voice Tracking is accessed at http://[camera-ip]/voice-tracking or from the Voice Tracking link in the Horizon Web UI sidebar. It is a licensed add-on that requires activation before use.
How It Works
Voice Tracking connects three systems together:
Microphone → Voice Tracking Application → Camera(s) + Optional Switcher
- A microphone listens for audio and reports which zone(s) in the room are active.
- The Voice Tracking Application (running on the camera) evaluates zone activity against configurable thresholds to confirm a real speaker is present.
- The assigned camera recalls a saved preset position corresponding to that zone.
- An optional video switcher simultaneously cuts the live program feed to the active camera.
The result is a hands-free system where the camera follows the conversation automatically.
System Architecture
Single Camera, No Switcher
Mic → Voice Tracking Application → Camera (recalls preset per zone)
The simplest deployment. One camera moves between preset positions as different zones activate. Best for conference rooms, classrooms, or single-presenter environments.
Multi-Camera with Switcher
Mic → Voice Tracking Application → Camera 1 + Camera 2 + Camera 3
→ Switcher (cuts to active camera)
The most capable setup. Each zone maps to a specific camera and/or switcher source and preset. The switcher cuts the live output to whichever camera is covering the active zone. Ideal for studios, podcasts, panel discussions, and large conference rooms.
