Understood. Do you have other smart devices connected to your Google Home? If so, can you control it using your speaker? Try removing and adding your devices from its native app. Resetting your speakers might help too. If the issue persists, we'd suggest contacting your camera manufacturer for additional assistance.
Thanks for the update! Glad to know that it's working!
