Hi @jalynb2024,
A warm welcome here in the Roku Community, and thanks for the inquiry!
Please be advised that Roku Smart Home cameras all include motion detection alerts, they can't tell a tree from a person. A subscription includes Smart Detection to distinguish between a person, a package delivery, a vehicle, or a pet. This gives you the option to only receive alerts when a person is detected if you so choose.
You may also want to check out this support article here on how to use smart detection for your Roku Smart Home camera or video doorbell.
Hope you'll find this info useful. Let us know in case you still have any questions.
Kind regards,
John
