A bit of advice to anyone using a dashcam. I see a lot of people complaining that theirs is playing up, and other advice to regularly reformat the card – which seems to get a lot of people recording again. I strongly believe that part of the problem is with the card, and not the dashcam. Specifically, people are using the wrong cards.
I have always used SanDisk Extreme cards in my dashcams, and I have not had any problems. Extreme cards are not the cheapest, either. They’re pretty high spec. However, I recently wrote to SanDisk and asked them if Extreme cards were OK to use in such applications. Here is what they replied:
Thank you for contacting SanDisk® Global Customer Care. Please allow me to inform you that for Dashcams & security surveillance cameras, we recommend to use SanDisk® High Endurance Memory Cards since these cards are specially developed for high endurance applications and continuous read & write cycles. These cards are built for and tested in harsh conditions and are temperature-proof, shock-proof and waterproof.
Also, please be informed that using Extreme or Ultra line memory cards on these devices void their warranty.
So, using Extreme cards puts them under stress that they’re not designed for. It voids their warranty, but – more importantly if you read between the lines – there is a good chance they will malfunction or play up. I don’t know much about cards from other manufacturers, but I would lay odds that most people with dashcams are using the cheapest card they can find, and they certainly won’t be paying the extra few quid that goes along with high endurance types. Most of the time I see people asking what dashcam to choose they always want a cheap one, and the one they end up buying often costs them less than I pay for a SanDisk Extreme card – so there’s no way they’re going to buy a card even close to that.
I have a GoPro camera that records in 4k video. I bought a high capacity SanDisk card designed for 4k that I had to import from the USA because they weren’t available over here, but before I got it I tested a normal SanDisk Extreme card and the video was as choppy as hell. It wasn’t the card’s fault directly – it just wasn’t fast enough for 4k, and it wasn’t supposed to be. I’m fairly certain that this is one of the problems people experience when they use a card that simply isn’t up to the job in their dashcam.
NextBase insist that Extreme cards are compatible with their devices, and their own cards appear to be rebranded SanDisk ones. I don’t disagree that they work well for me, and probably for everyone else when they’re new. But the niggling problems people keep reporting might not be doing NextBase any favours, because I firmly believe that a lot of them are down to the cards protesting at being used outside of their specification, but the user blames the dashcam.
SanDisk high endurance cards only go up to 64GB, though other manufacturers produce higher capacity units.
