High pitched whistle on Video Doorbell Elite

Hi guys, I have a video doorbell elite and recently it has started to record a high pitched whistle when there is movement. It disappears when there is some other sound but otherwise is intolerable.

I have recently replaced my router, and the doorbell is connected via Ethernet cat 6.

AnY ideas/suggestions?

Is this sound coming from the Video Doorbell Elite itself, or is it only present in videos? Try power cycling the Video Doorbell Elite by powering off the PoE for a few moments, then powering it back on, ensuring the Video Doorbell also powers off and back on. Feel free to let us know how this goes! :slight_smile:
