Thanks for posting here in the Google Nest Community.
This is not the experience that we wanted you to have, let me help you out. A few things: is it a Nest camera? Were there any recent changes made before the issue started? What is the distance between your Nest camera and your WiFi router/repeater? Do you have other cameras linked? If so, are they doing the same thing?
You can reboot your camera and your WiFi router to refresh both devices and WiFi signal, then observe if this will make any difference.
Looking forward for your response.
