Thank you for attending the Dante AV Webinar with Audinate.  Now, let’s answer some of your questions that are related to Bolin products!

  1. Please describe the network topology of a Dante joystick controller for their cameras.
    • Our Joystick controller supports Visca Over IP protocol and can directly connect to the Dante network switch to control the Dante AV PTZ camera.
    • Serial control and IR remote control via Dante network will be supported as well
  2. Is the video spec 4K 4:4:4, Is PTZ supported by Dante AV?
    • Yes, Dante AV supports PTZ cameras that have an integrated Dante AV module. The Dante AV codec supports video 4K 4:4:4, our PTZ camera supports 4K 4:2:2.
  3. No need for encoder and decoder for Bolin PTZ camera?
    • The Bolin PTZ camera has a Dante AV encoder built-in, so there is no need for an external encoder. However, it does need a decoder for displaying HDMI video signal.
  4. Do you just plugin the network cable and control from their proprietary software?
    • Yes. Once you plug-in your PTZ camera to the Dante AV network with a network cable, you can use Dante Controller software to route the video to the endpoint.
    • Please note, when you use the IR remote controller or PTZ keyboard controller to control the PTZ via Dante network, there is no proprietary control software.

  55. Does the Dante need to be run on a separate vlan on the network?
    • Only if you want it to.
    • Special network infrastructure or dedicated network infrastructure is not required for Dante AV network.
  56. Can you mix the Dante network with the corp network?

  60. How is Dante AV different from NDI ?
    • Dante AV camera seamlessly works with Dante Audio Over IP ecosystem. The Video codec is different. Dante AV uses JPEG2000, which provides low latency video and 100% synchronization with audio, that can be routed using Dante Controller within the Dante system.
  61. How would you compare Dante AV to NDI from Newtek?
    • Dante AV camera seamlessly works with Dante Audio Over IP ecosystem. The Video codec is different. Dante AV uses JPEG2000, which provides low latency video and 100% synchronization with audio, that can be routed using Dante Controller within the Dante system.
  62. What’s the advantage of getting a Bolin 4k PTZ if the video is going to be compressed? Why not make them 1080p?
    • The compression is remarkably transparent. 4K looks like 4K, and 1080p looks like 1080p. You can easily reduce resolution to fit applications.
