WyzeCam "eating" micro SD cards?

You would only be able to view the 12 second clips and live view. Any stored video other than the events in the cloud would not exist.

I’ve had four wyze cams (2 wyze cam, 2 wyze cam pan) running for over 6 months now. I’ve bricked 3 SD cards. One of the Pan’s bricked 2 cards and one of the non-Pans got the other one.

All four cameras have been set to “continuous recording” mode since they were installed.

To be fair the non-Pan that bricked a card is working outside of the recommended environment. It’s mounted under a covered porch outside of the house. It doesn’t get wet but it is exposed to cold (below freezing) temperatures.

I plan to fill out the support form posted by WyzeGwendolyn a few weeks back.

I continue to use the two cameras that eat SD cards but I do not have SD cards installed in them. It’s not an ideal situation, I’d like to have continuous recording.

Have you tried the format utility

“Sd Card Formatter” 5.0.1 by Tuxera?
link
Also what size/speed/brand cards are you using?
/edit - what capacity? where did you format them? (pc, ios, android, wyze)

The outdoor wyzecam had a 16gb SanDisk Ultra UHS speed class 1 , HC I. The Pan cam has a 16gb SanDisk Ultra Plus UHS speed class 1, A1, HC I. I don’t have the first card handy that the Pan ate but I’m pretty sure it was a Samsung 32gb EVO UHS speed class 1.

I’ve tried the 5.0.1 program on the two SanDisk cards, no luck. I’ve also tried the gparted program under linux with no luck.

I don’t remember how they were initially formatted, probably as fat32 with a windows 10 machine. They all worked for a while and then stopped working.

hey @Ken

some cards just aren’t made for continuous read/writes. many of sandisks actually list security cameras as a cause for voiding their warranty.

when you get a minute check this topic out, we are trying to gather a list of good and “bad” cards for our cameras.

make sure when you buy cards, buy “endurance” cards that are made for things like our cameras or dash cams that do continuous reads and writes, they will withstand what our cameras will put them through

As @Bam just said, most micro SD cards are not designed to be used in Security Cameras. You need one that is specifically designed for extended video monitoring such as the Transcend High Endurance microSDXC card (TS32GUSDHC10V). I use these in dash cams that hammer other micro SD cards and destroy them in a matter of hours.

I guess it’s time for us to reconsider different SD cards. Thanks for your input☺

I purchased four of these Samsung cards you are recommending - I am afraid to actually use them, though . . . !

Get the Wyze brand SD cards, if they die they are warrantied by Wyze - They just shipped a replacement for my dead SD card the other day…

just put it in the camera, format it when you get it in there and you should be set. I’ve had all of mine except one using the Samsung card for months and haven’t had any issues.

I have been using Sandisk 16GB chips in 4 cams. Sure enough a couple of the chips went bad. One went into permanent write-protect mode. The other became unreadable.

But I utilized the Sandisk warranty RMA process, and sure enough they swiftly sent me replacements.

Reformatting these chips is tricky. I experimented, and noticed that while using the Windows 10 format dialog, it was important to use the “default” block size (whatever that value may be), otherwise the cam could not wake up.

The block size affects the number of allocation units on the chip. Small block entail more allocations. There seems to be a threshold which tanks the cam’s OS.

i bought a couple of Cam V2 a few months ago and was about to set them up (yeah, i’m a procrastinator!). and then i came across this thread so i’m a little nervous about getting my new SD cards trashed.

  1. is there any indication about how pervasive this issue is?
  2. is the SD Memory Card Formatter 5.0 that has been referenced been able to resurrect the SD card or is it gone for good?
  3. what would be the recommendation - leave the cards out until the issue is resolved, only record events, reformat the card every so often, etc.?
  4. has there been any indication if this is a hardware issue, firmware issue, etc.?

thanks!

To echo what some other users have said, high endurance sd cards are a must if you are using continuous recording. Samsung Pro Endurance are specifically designed for this and the 128 GB version will last through 5 years of continuous recording.

Excerpted from https://www.samsung.com/us/support/service/warranty/MB-MJ64GA/AM is Samsung’s alleged warranty. It appears that the 128 GB is 5 years, but that card is #pricey #lotsadough

Why do you think the 128GB is “pricey”? It is about the same $/GB as the 32GB. Now if it would work RELIABLY with the Wyze it might be worth it. But I’ve tried 2 cards > 32GB and they didn’t work well.

Just a follow up… I had said the first memory card that the Pan cam ate was a Samsung 32gb EVO UHS speed class 1… and I was correct, it was. Just to be accurate, the camera did not totally destroy the card, it just made it seem toasted. While at the camera location this weekend and using a windows 10 laptop I was able to reformat the card in the laptop. It took a long time to format…after 15 minutes of formatting I went on to do other things and when I returned 4 hours later the card was formatted and I was able to copy a file on to it and read the file back.

So in the end only two SD cards were destroyed. One a SanDisk Ultra and the other a Sandisk Ultra Plus.
