so increase the specification, improve the support and distribution, and lower the price and they'll sell more, did I miss anything??
No, but nice commercial sarcasm...
1. It's seems to be missing a few specs for carcam use which are frequently wanted from purchasers from here and are mostly software related eg parking mode.
2. An optional capacitor pack, wouldn't go amiss although no reason why this couldn't be either an accessory or 2 versions of the camera - it's only a matter of putting something different in the box, and price wise, I would bet a li polymer battery costs more to supply than a capacitor pack.
3. It's expensive as car cameras go - one way around this might be 2 versions as I touched on above, a wide angle sports cam with battery pack and a carcam version with 90 degree longer focused lens and capacitors. That way provided the margins are there, you could sell the carcam version much cheaper without losing the greater profit margins from the sports cam market as a narrow angle, longer focused capacitor equipped version wouldn't be of any use for sports use other than maybe drone applications.
4. As for support, touched on this before, many (I would suggest most) Western European citizens don't want to buy from Chinese web retailers because there's often poor support and no legal protection.
eg In the EU, if you buy a product over the web, and don't like it, then you are entitled to return it even if nothing is wrong, even if opened and used (provided still in a new like re-saleable condition - if packing was unavoidably damaged opening it eg memory card in rigid plastic sealed enclosure, sealed plastic bags opened, then damaging the packaging in that way doesn't prevent the return). Also, it's illegal for the retailer to charge restocking or handling fees, and they have to refund the full price of the item including the outbound postage, and the return postage if the terms at checkout didn't exclude the return postage refund (the retailer can't exclude the refund of the outbound postage in any event, he has to accept the loss of that as a business expense). If the product is defective, then again the consumer has a whole raft of legally enforceable rights in respect of replacements or returns that give the consumer quality rights for up to 6 years after purchase.
You get none of that from China, long turn around times for repairs, plus return postage to China is expensive.
That's why EU consumers are often reluctant to buy direct from China.... quite simply no enforceable consumer rights, import taxes and customs issues.
