Eufy (Anker's electronics brand) has announced a kickstarter campaign for a new line of security cameras.  These are similar to Logitech's Arlo line of cameras that have received some loving over at Sailbits

I realize this isn't a marine product but I suspect for many uses this would work well.  I'm really liking the idea of the receiver hub in the boat with recording capabilities and no requirement for a cloud subscription.  Not to mention $3 a month / camera if you chose to subscribe to cloud backup is awfully reasonable.  

The 3 camera / 3 entry sensor option is kind of calling my name.
