  • [POE] Recommended speed of wifi to use full features from POE camera

Hey all,

So far, I have been having a painful time with OAK-D-POE and OAK-D-POE-PRO cameras. I cannot even capture a frame in 12MP resolution. When I run the script to get 12MP image, the program simply dies with this message, "Ping was missed, closing the device connection". I thought it can be an issue with their firmware, but I have to think about different factors and check they make differences or not.

I would like to check with you that what the recommended wifi speed is. Just did internet speed test the google provides (https://www.google.com/search?channel=fs&client=ubuntu&q=internet+speed+test) and got 58.7 Mbps for download and 31.8 Mbps for upload speed. Are they good enough to utilize the full features from POE camera?

I am using Ubuntu 20.22 LTS and maybe the insufficient buffer size occurs the connection drop?

I really want to make these cameras work for my project. Would much appreciate your feedback.

    Hi GeonsooKim ,
    The error you are getting is very likely due to WiFi connectivity. We recommend using ethernet cable instead, especially for large frames like 12Mp. You can calculate the bandwidth required for streaming of 12MP and then determine whether wifi is ok. Thoughts?
    Thanks, Erik

      @erik you mean use ethernet cable between host pc and router?

      Currently the POE cameras are connected to ethernet switch and the switch is connected to router.

        GeonsooKim Yes exactly, to have the computer (host pc) connected via ethernet cable to the router. Could you try that?
        Thanks ,Erik

            erik I need to buy a “usb-c to ethernet” adopter, so it might take a couple of days. How about connecting host pc to the etherent switch? Does connecting directly to router make difference compared to connecting to switch from host pc?

                Hi GeonsooKim , I don't think there should be any difference if you connect to router or switch. Perfect, let us know if it will work as expected🙂
                Thanks, Erik

                  Will do. Thank you so much for your feedback.

                  Best regards,
                  Geonsoo
