Similar to this issue here, I have gone through several micro SD cards of varying brands over the past few weeks. Brands include Lexar, SandDisk, Silicon Power and TOPESEL. I have tried on continuous record as well as event-only and they’re still dying. This happened on my interior OG as well as my exterior.
What is wrong with these cameras?
That is the wildest thing I have never experienced. 
I have used µSD cards since 2019 in Wyze cameras without issue. I wonder why yours dies. The reports seem to be increasing but why are they dying? A true mystery.
I would try a High Endurance Card that is at least 128GB and see if that solves the problem. At worst, you’d get it replaced through the SD Card warranty.
Non-endurance cards technically aren’t rated for smart camera use due to the rigorous constant recording (so their warranty isn’t valid if used in a smart camera), but I’ve still never had any of my cards go bad in any of the camera models. I’m not sure why these reports seem to be increasing and I still have 50 cards in cameras of every model, many since 2019 or since a particular model launched, still going strong. But if this was happening to me, I’d be switching to High Endurance and getting free replacements when it happened.
It has still continued to happen to mine. I have put various cards in those cameras and they last less than a month. I mean, there’s nothing I can do so I put those cameras in less important places and hope for the best. And put the V3 cameras that I have in areas where I actually need the camera to work when I’m gone for six months at a time. It’s a shame.
Maybe Wyze can acquire the dead cards to see why they are selectively dying. I am curious to learn the cause, but that’s just me.
What kinds of various cards - good brand (Sandisk/Samsung) endurance cards?
Something you said in your original post caught my interest,
“event only” should last basically forever. If you are seeing failures while in this mode then I would be getting nervous.
@ssummerlin suggested sending some failed cards to Wyze. Good idea.
Maybe a maven can use their superpowers to facilitate this.
As others have posted, I to have been using Sandisk/Samsung cards for years without a failure. Just recently started to use High Endurance cards as the price has come down.
My brain is busy trying to think if an environmental condition could cause this. So far nothing comes to mind unless you have lightning bolts surrounding your property.
Depends where it is, some of mine, even if they were on event only, would be recording motion pretty much constantly (even if not tagging it as events except for every 5 mins).
Good point @dave27,
Only going by my experience. I have a WBCP that has been running “events only” for almost a year. It gets about 10 events a day. The 128gbyte SD card shows 4gbytes used. I do not believe it has ever rolled over.
Compare that to my other 9 cameras that record continuous - - and roll over in days to a couple of weeks, depending upon card size (32gbytes to 128gbytes).
I keep seeing this issue pop up from time to time, it has made me curious and a bit nervous.
how do you know the cards are ‘dead’?
There have been issues reported with cameras not recording to cards or recognizing cards recently, Started with Pan V3, but has moved to OG’s I’ve seen recently.
Maybe a firmware issue? … Or even an App issue? I haven’t tried to remove my card and see if there’s anything actually on it. But pretty sure I can read it
I don’t ever remove my card since I see it works fine through the app. My photos and downloads sync over to my gallery.
Your spot on.
When the SD card has run out of “writes” it is supposed to “Write Protect” the card thus preserving the data on the card. You should be able to see the data on the card. Since this has never happened to me I can only speculate that you have to remove the card and put it into a PC. I doubt if Wyze allows you to view the SD card as it may consider it defective as it cannot control it. If your data is there then I would submit that the card just ran out of “writes” and did what it was supposed to do.
If however you are not able to read the card than the card has neen bricked.
What could cause this.
Fake card–used to be a big problem, but at least the biggies (Amazon, New Egg, etc) have gotten rid of the bad actors.
Card electronic failure–it happens
Environmental issue - - to hot
Design flaw–possible but doubtful considering the number of units installed.
Anyway. If your seeing this problem let us know if the card is readable in a PC.

The cards are no longer recognized by the PC. They’re definitely dead.
My cards have been dying before reaching capacity and without having been used prior to putting them in the camera.
I wonder if they make a diagnostic program for micro sd cards?
Is it write-protected?
Can it give an error code?
Is format disturbed?
Was it burned by a power surge?
Is it physically damaged?
And…
Why does Steve have no issues with micro sd cards? 
Thanks for the update. I’m going to dwell on this for a while. I have noticed some anomalies with the OG’s on this forum. I want to think it through before replying.
Good question about diagnostic program. Back in the day there were extreme read/write/seek tests for spinning disks. I am not aware of any diags for testing a SD card–especially if you can’t read it at all. Time permitting I may look to see if such a program exists. Forum members–if you know of such a diagnostic program chime up
My card is fine, I’ve tried multiple cards and they’re always fine. My pan V3 just won’t record to the microSD. Sometimes it says the card is unsupported and sometimes it just doesn’t write.
Seems my problem is different then the problem YOU’RE seeing
That would be great to find something and get to the root cause.
It would be cool it you could check resistance between the connections to find an equivalent short or open. Something. Anything.
I’m not the one having the issue. Like you trying to help narrow it down.
If I’m reading @JamesT6 posts he is seeing bricked SD cards on pan Scan v3’s and OG’s.
I hate to say this but I wish one of my SD cards would brick–so I could at least have a sample😬
Sorry if I implied that. I might have meant we instead of you specifically.
I feel the same way of getting a bad cam to work on, but then who needs problems.
My cards are dead as a doornail. They don’t work in the Wyze camera, and when I plug it into the PC it’s like it’s not even there. I tried all kinds of things recommended for corrupted SD cards when this first started happening back in February, but I really don’t remember what all the things were now. I’ve tried various brands of card, the first couple were Samsung and Sandisk. Among other cheaper brands. The same cards that I’ve been using in Wyze cameras since I first started buying them back in the beginning. It’s worth noting that not all of my OG cameras do this, however, they were all bought at the same time close to the release date. It has happened at two different locations 2000 miles apart, so I don’t think it’s a power issue.
