Greetings @Chrisdaman
Welcome to the Roku Community and thanks for the inquiry of how many cameras can be connected at the same time.
Please be aware that if you have a Roku Smart Home subscription, the subscription will only cover up to 99 cameras linked on your Roku account. If you have more than 99 Roku Smart Home Cameras that you would like to be linked to a Roku Smart Home subscription, you would need to create another Roku account and have an additional Roku Smart Home subscription for another 99 cameras to be covered.
For more information about Roku Smart Home subscriptions, visit our Support page here: Roku Smart Home Subscription—Unlock Cloud Recording
Happy Streaming,
Danny
