We have a Foscam that was purchased 2 years ago, model number FI9821P V2 , version 2.2. We will need to register for / buy a 2nd one for baby #2. Are the newer foscams compatible with the same app? I know that sounds like a dumb question, but I'm not a techie-type person.

The Foscam we have doesn't have motion detection pictures or video storage - like, we can take pics or videos ourselves if we are watching, but it doesn't take or store videos or pics by itself if something were happening in the crib/room. It also can't zoom in. I'd like both of those features, if possible, for a decent price.

I was looking at these 3 and wasn't sure if the extra features were worth the money?
