I propose a simple: all names have to be lowercase; words are separated with underscore.
Lowercase names are more compatible in general case.
There is a lot style blending, even in a single table... For example "created_time", "accessLevel", "lastIP", "pcIp" columns in accounts table. It's some salad of styles

It really doesn't look pretty for me as for programmer.
