Looking to purchase Arlo for boat. Not model is best. Recommendation?

[DanDanBoatMan]

Hi all - I'm looking at purchasing an Arlo for our boat - unsure which is the best model.  The boat is big, 75ft.  so we are looking at 3 cameras. The camera that will be facing the back, will be placed inside and Im hoping that if directed correctly the camera will film through glass. 

Im looking for recommendations for the best and easiest camera... I will be linking it to my iPhone.

Most of the Arlo camera will NOT work thru glass as they use a PIR detection...

Only the Q cameras will work thru glass as it uses pixel detection ( when view changes )

Also they do not directl link to an iphone, the based Arlo cameras need ethernet connection and the Q cameras need a wifi access point
