Need help with camera notifications

Hi ive had numoris issues with my cameras turning off notificatiins turning off the camera setting times it stops notifying me and im wondering
Can I go into the code remove the turn off notifications and turn off camera buttons/actions in the app
So my cameras run continuously without beibg shut down remotely or other then me unplugging them?
Also anyway to encrypt the application on my andriod device so it requires a key or code to get into it?
