Thank for the post.
Can you please clarify your inquiry? In order for a camera to be linked to another Roku account, the camera would need to be factory reset and then re-activated. In addition, to view a Roku Smart Home device, a user would need to have access to the Roku account that the Smart Home device is linked to.
With more detailed information, we will be able to assist you further.
Thanks,
Danny
