May I assume that you can sign-up for Cam Plus after you have installed your cameras?
Yes, give up the money and you can get CP anytime.
You can upgrade to Cam Plus at anytime. More information can be found here:
I want to sign up two v3 cameras to Cam Plus. When I follow the link, it takes me to a page where I am logged in but I don’t see where / how I can specify which of my four cameras I want to sign-up for Cam Plus. Any ideas?
After you’ve subscribed and activated from a code you receive via email, you can select from within the app which cameras get the Cam Plus subscriptions.
The nifty thing about this, I can change which cameras have Cam Plus, depending on what I need to monitor for the day or week.
