Perfect but almost nonexistent documentation

This kit is perfect but there is no documentation worthy of the name. Installation is simple once we have understood that it is imperative to plug in the ethernet box car wifi CPL that does not work that great.
As against the road up there is a hassle because the doc explains nothing, fortunately there has ADVANCED USERS Google to help us.
In addition there are 3 or 4 days there has been a big shift on the android app, operation changes but again we are left with no doc with very little explanation. On holiday period is very limited.
This explains the 4 stars if not for the rest it is a good product, we are delighted simple and hopefully effective
