On one hand if someone says a certain card works and on the other, 1000 people say that it works, both do not guarantee smooth operation of the card. But I'm more likely to be successful if I rely on the experience of the 1000 people. Wouldn't you agree?
If there is no certainty of card efficacy across all brands, then no one should entertain the idea of an aftermarket card as that would be futile. However, Thinkware, a company who doesn't even make chips, has managed to maintain internal consistency.
So, no. This is not voodoo magic cursing the cards and the f750 can only descriminate cards based on whether its formatted correctly and writes fast enough. Nothing else is happening. It's a sh1tty, cheap, dashcam made by a company who probably thinks they are the market leader of all the other providers with their particularly sh1t products. Thinkware along with every other dashcam provider is generally garbage, in quality of manufacturing and operation.
No dashcam around looks good, they are all ascetically ugly. No dashcam takes advantage of state of the art mobile tech, it could easily stream using 802.11ac or have inbuilt storage. They are all overpriced for garbage decade old 1080p. I bet someones got a 4k out there and it's 1500 and looks like an 80s modem stuck on your windscreen. I should be able to connect via wifi, press one button to transfer all content from the dashcam to the connected device. But no, it's garbage, screwing about with memory chips.
This industry is a deadend, as you know. In the near future cars will come with this functionality as standard, and they will be designed to look and function just like radios in cars of today. They use to be optional and now are ubiquitous.
Thank goodness. I will fondly recount these annoying but necessary dashcam escapades with my kids in 10 years' as that dark time when in order to prove some imbecile ran into you, you needed to spend $800 bucks to stick an irritating and poorly functioning box on your windscreen. The only reliable feature is the recording, everything else, collission warning is hilariously dumb along with lane departure, it also runs batteries flat even with the 60 bullsh1t add on so must be unplugged in the garage. Even the 32gb thinkware card that came with it died after 6 months.
