How many Cameras...

Allegedly the current version of the App and online dashboard will handle 10 cameras, and they are "free" with the $25 a month monitoring plan

Cabers have one time charge.  seven is saying free monitoring of up to 10 cameras with $25 a month monitoring plan.

The cameras are not free, but there is no monthly charge for up to 10 cameras if you have the top monitoring plan.

C'mon, guys, make it simple. lol.  

If user has standard monitoring plan (14.99/mo) + one camera (4.99 subscription charge/month) = 19.99/month total.

If user adds a second camera, that's an automatic upgrade to the interactive monitoring plan* (24.99/month total) which can support up to 10 cameras at no additional charge.

*Cameras purchased separately.
