  1. Studio Monitor is not finding my PTZOptics camera(s)

(Note this also applies for Upgrade Tool discovery issues)

  1. Different Subnets
  2. mDNS is not configured
    • Typically only an issue with more than 1 switch
    • (Note a router with switch built in counts as one switch)
    • May require static entries in the NewTek NDI® *.json for each camera (PTZOptics NDI® JSON Generator)
  3. Network Configuration (VLANs, subnets, segmentation, etc…)
    • Attempt to launch NDI® Test Patterns on a separate PC connected to the same network as the PC with Studio Monitor; if you are unable to see the test patterns, NDI® source, you must contact your network administrator for further help.
    • May require ports 49152 - 65535 to be opened noting if NDI® devices are used on networks with firewalls positioned on the internal network, configuration to allow for traffic between devices in this port range is required.
  4. If you are still having problems getting Studio Monitor to detect your camera, please see the article on using the Access Manager
  1. Studio Monitor finds my PTZOptics camera(s) but only displays a black screen
    1. Multicast Issues
      • Network is not properly setup for multicast
        1. Disable multicast on the PTZOptics camera until the network configuration can be resolved
        2. Note this will limit the NDI® source to only be pulled to one station at a time.
      • ®More than one (1) camera has the same multicast address
        1. Check the multicast address of each PTZOptics camera and make sure they have a unique multicast address
    2. Video Settings aren’t configured properly
      • Make sure the NDI® Mode is enabled (High / Medium / Low)
      • Make sure that the i-Frame interval is set for double (2x) the current frame rate (fps)

    1. IP Conflict
      • Make sure no other camera has the same IP address as the camera you’re trying to connect to
      • Make sure if multicast is enabled that each camera has a unique multicast address 231.1.2.XX
  3. Studio Monitor finds my camera(s) slowly but takes a long time to connect and or eventually crashes studio monitor or causes the camera to reboot
    1. Typically occurs when the VISCA ID has been changed via the WebUI
