Hey @stg-ring. Thank you for taking the time to write about what is happening with your Floodlight Cam and sharing this video! There could be a concern with the wiring or the device to make it produce this loud buzzing sound. To confirm this and troubleshoot further, please give our support team a call at one of the numbers available here. We’re taking additional steps to protect our team and help reduce the spread of COVID-19. This has resulted in longer than normal wait times. If you are outside of the US, please read our response to COVID-19 here to see how to contact support. Please come back and let me know how this goes!
