    Hi kle
    You have missed a ping 🙂. What is your networking like? Monitor thread can usually shutdown connection on events when bandwidth and/or network stability isn't adequate. Make sure to double check that you have adequate 1Gbit link between you host and the device (preferably no WiFi in between).
    Really, any data loss could shut down the connection to the device.

    Thanks,
    Jaka

        Hi jakaskerl
        The camera is connected directly to Raspberry Pi4's ethernet port. Pi4 has a dnsmasq which provide a static IP to camera based on camera's MAC.
        Could it be that the camera is too busy for replying the ping?

            kle What's the CPU usage of the OAK camera? If it's above 90%, then that's likely the issue.
