I was recommended to buy a camera from Boyo, VT-series. I go to ebay and what I see is plenty of diffeent models: VT110, VT300, VT375, 4xx-something and etc... All of these have identical visual appearance: a license plate frame with a camera built-in on top of the frame, all share similar cost price.

What do these model numbers mean difference-wise?

is there not a boyo website you can go in and do some comparisons?
