To be fair the dominant markets are Russia, Korea and Taiwan so the products are aimed at those markets and the requirement is much different to what is preferred in western markets, most (99%) are happy just to chase those markets and if they pickup business outside of that then consider it a bonus, for me I'd never try and compete in those markets as they are spoilt for choice already with more than enough products to choose from, the requirement they like is not what I personally believe makes a good product so they're products that I wouldn't particularly want to be involved in anyway, it's not about the money
I've found a few manufacturers that I felt had potential to do good product for our market and offered to work with them to develop product but none have been interested in doing that, they seem to be quite happy just chasing the existing markets and aren't worried about the emerging markets, sure the big three (Russia, Korea, Taiwan) represent big numbers but they're competing with many more suppliers, the growth potential is much higher in western markets where they are only just now beginning to wake up to the idea of dashcams, now is a good time to be getting into the other countries, some get it, most don't
