Since Cam Plus is a single-license plan that only covers a single Wyze Cam on your account, and Cam Unlimited is an account-level plan covering all Wyze Cams on your account, Cam Unlimited will override Cam Plus.
Note: On May 8th, 2024, existing Cam Plus Unlimited users were automatically switched to a Cam Unlimited plan with all the new features included. This includes a self-monitoring security mode and no limit to the number of cameras covered by your plan. It's truly unlimited!
