Voice-based PTZ camera control

  • Are you having difficulties following different speakers during the video recording of a conference?
  • Do you need to automate video and audio recording for presenters and panel discussions?


That is where Voice Based PTZ Control comes in!

When using Panasonic PTZ cameras with Sennheiser microphones for audio-based tracking, the PTZ cameras can automatically switch focus between different speakers. With automated and smooth camera panning, it’s ideal for online conferences, training courses or lectures when questions are asked from the floor, or a new person speaks at the conference table for example.

The solution uses Panasonic PTZ camerasTeamConnect Ceiling 2 (TCC2) microphones from Sennheiser and a special module development from Systemhaus Pauly. They are managed centrally by a controller via the network, using a media control system Such as the CP3 or CP4 from Crestron.

Audio-based tracking opens up a range of new possibilities and can be used in conjunction with Panasonic’s existing Auto-Tracking Software (AW-SF100 / AW-SF200). The systems are complimentary with each other, for example at a conference when a main speaker can be recorded via auto-tracking by a PTZ camera while other participants are filmed with a second camera when they speak using audio-based tracking.

The settings for the audio-tracking can be adjusted individually and saved as a preset. For example, priority can be given to individuals to avoid unintentional panning to conversations in the audience. Clip-on microphones can also be integrated into the AV recording schedule and prioritised accordingly. A slight time delay can also be set for the PTZ camera, so that it only pans once there is a permanent audio signal.

For speakers, this new solution makes things much easier. They no longer need any technical know-how, or a camera operator, or a mixer technician on site. The speakers can concentrate solely on their subject matter, while the speeches are recorded automatically.

Companies that already use PTZ cameras from Panasonic, Sennheiser microphones or Crestron media controllers can take advantage of the solution. Various different cameras and microphones can be combined depending on the size and use of the room. One Sennheiser TCC2 microphone can cover a room up to 60m2. Several microphones can be used for larger spaces.

The audio-based control of PTZ cameras increases the level of automation and makes handling more convenient. In addition to the broadcast-image quality of the PTZs, these are a huge advantages for the ever increasing needs from e.g. board members and politicians that are reliant on online formats and universities that are teaching digitally or in new hybrid settings.
