Lumens VC-TR60A 4K Dual Lens Speaker Tracking Camera incorporates an array of directional sound sensors that detect the location of active human voices. The camera head moves and zooms to shoot the current speaker, re-framing as other voices enter the discussion. VC-TR60A supports a reference audio input (USB or line in). This eliminates remote side audio interference, ensuring precise and reliable voice-tracking of speakers within the room. VC-TR60A features sophisticated auto-tracking and framing modes. Its intelligent human detection algorithms deliver smooth tracking for conferences, presentations, meeting rooms, classrooms and studios. VC-TR60A can combine the two video images in a picture-in-picture display with output over HDMI and USB. This allows the audience to watch a composite video that incorporates both the wide-angle view and the tight shot. This function can be activated independently, or at the same time as running motion or voice tracking. VC-TR60A generates two video streams from its panoramic fixed camera and the robotic zoom head. These can be delivered over IP into a media processor, IP-based production software or a lecture capture system to provide two camera angles from a single unit.
