Is my Internet not fast enough for an indoor camera?

I have a new SS system,  Orbi 54 gig router, but my connection to the internet is 50/10  over radio signal to tower with some latency, but not so bad that I can't do online gaming.   I lowered my camera to 480p but it says my connection is weak. The camera is 25 feet from my router and 4 feet from the SS hub.  I have a second camera, but I am concerned it would crush my bandwidth, so I haven't installed it.  

Is my setup too slow to have cameras?  

Do the cameras monitor all the time or only when in alarm setting and/or when I choose to view live?  

Also, it seems to drop the connection often.
