I have the reolink RLN8-410 with cameras attached to it. I don't see any way to upgrade the CAMERA firmware through the NVR. Is it possible? I have updated the NVR firmware to latest available.

From google:

"On May 30, you may lose access to apps that are using less secure sign-in technology.
To help keep your account secure, Google will no longer support the use of third-party apps or devices which ask you to sign in to your Google Account using only your username and password. Instead, you’ll need to sign in using Sign in with Google or other more secure technologies, like OAuth 2.0."

Reolink NVR uses smtp to send alert emails but these will not work after may 30. Can you offer a solution for NVR users?
