Thanks for reaching out. Could you tell us the type of Nest camera you have? Also, do you have an active Nest Aware subscription? If so, try the steps below and let us know how it goes.
Its a battery Nest Doorbell, and yes have an active Subscription
I already have some faces detected, and new faces have popped up ie Postie leaving a parcel.
I have a specific person that the face is not detecting.
I have already tried switching face detection off/on and have done it again.
The other thought I have is a maybe a device reset
Thank you for bringing up the concern you're experiencing, I would love to look into this further for you. The first troubleshooting step that I'd recommend would be to restart your device. This process should keep all your settings, and reconnect it to the same Wi-Fi network. This is helpful if it ever freezes, has connection problems, or isn't working normally.
I just wanted to follow up to see if you still need our help. Please let us know as we would be happy to answer any questions you may have.
I appreciate the help, Brad.
As we got our resolution here, I'm going to mark this thread as resolved. I'll be locking this thread if we won't hear back from you again in 24 hrs. Should that happen, feel free to create a new one if you have more questions or have other concerns in the future.
