replacing a Pro 3 camera

[itisme2]

Thank you for the helpful info on how to discover what kind of Arlo camera I have since I need to replace one that died.  I opened my camera & saw I have a Pro3. 

Please help me understand the last part of your info. You wrote: "If you purchased a while ago, you likely have legacy cameras, and will need to pick a different model.

Legacy cameras were sold with free 7 days of cloud storage, and all the recordings you see in the app and my.arlo.com are stored in the Arlo Cloud.  Currently sold camera models don't come with that feature...

If I buy a new camera to replace my broken one, will I be able to use it with my other cameras? Will it work & give me a video when it catches something? I don't understand. I will have to buy a subscription for that one camera? But will it still give me a 'hit' if I don't have the subscription? Please explain. Will I need to buy a whole new set of cameras & a new basestation since this one camera broke?
