Hi @Michelle66,
Thanks for the inquiry, and welcome to the Roku Community!
Please be advised that you can add a Roku camera to your Roku account without subscribing to the full home monitoring system; however, you will only be able to access basic features like live streaming and basic motion detection alerts without a subscription, and you won't have access to cloud recording or advanced features like person detection.
We hope this helps!
Best,
The Roku Community Team
