Is there a true 4K dash cam?
Picking out a fit dash cam can be really tricky. Do you know that there’s interpolated 4K and true 4K out there in the market? Yes, although some dash cams claim that they offer 4K UHD resolution, in fact, they do not. I guess for most dash cam users, they may not pay such detailed attention to distinguish if it’s real 4K. But if you need to, you can check the image sensor. For example, with the Redtiger F77, the image sensor is Sony IMX678, and it’s TRUE 4K. Rest assured with our F77 dash cam—the real 4K dual dash cam, true front and rear!
Is it worth getting a 4K dash cam?
Definitely, if it’s a true 4K dash cam, I think it’s worth the choice. The price of a 4K dash cam is relatively higher than that of lower-resolution dash cams, but if we’re getting one, I suppose we intend to use it for years. And the biggest factor people consider when choosing dash cams is clarity. So, imagine you’ve perfectly installed a constant recording dash cam in your car, and somehow it captures a very decisive moment, but when you play back the video, you can’t clearly see the license plate because the dash cam isn’t 4K clear. That’s an even bigger bummer than not having one in the first place.
How much memory does a 4K dash cam take?
Normally, a 128GB card can hold about 8 hours of recording. But here’s a little heads-up: the memory card in this Redtiger wireless 4K front and rear dash cam isn’t a standard SD card—it’s eMMC storage. The advantages of an eMMC storage card are obvious.
First of all, it’s a built-in card, so the stability is uncanny. Even if you encounter a crash, you won’t lose any video evidence. Second, the write speed of eMMC is 150MB/s, which is a massive 400% improvement compared to a normal SD card’s 30MB/s.
If you don’t immediately notice the performance difference in the firmware, just take a look at the durability: the eMMC card lasts for 10 years, far longer than traditional TF cards.
How long can you record in 4K?
We know that with its ultra-clear resolution, the recording content needs more space than lower-resolution footage. For a real 4K dash cam, the recording time is around 2 hours and 48 minutes with a 128GB card. If you’re using an SD card dash cam and need to save the videos, you may need to remove the SD card to transfer them. With an eMMC card, a USB transfer will do since you can’t take out the card.
Here’s one obvious disadvantage of a real 4K dash cam: the storage fills up so much faster, and you’ll have to decide whether the recordings need to be copied very often.
