Doesn't recognize SD card



I have 3 cameras running. They all have SD cards and all recorded video for playback. This week they need firmware upgrades. Now they don’t record and the message is that there is no SD card installed. I restarted them many times but that didn’t work. Anybody else experience this? And any fixes?


Have you tried formatting the cards on a different machine, then reinserting them?


Others have reported that SD cards are no longer recognized. It appears that some Wyzecams cause SD cards to become permanently non-functional. Details here:

If reformatting the cards (as suggested by camera2) fixes your problem, please let us know.

I have refrained from updating my cams with the latest firmware update.



I have 5 cams with SD cards …class 10 32gb … 3 of them are bricked. Corrupt … will not reformat on Android or Windows etc … Silicon Power Elite from Amazon … I have other devices with them and they are fine.


Ok…same problem here…

I ordered my sd cards from Wyze so I hopefully wouldn’t have a problem.

Set up one cam with card. As I remember, it formatted ok. Couple days later I wanted to review what was recorded and nothing. Tried reformatting,…app says sd card not inserted or not found whatever. Unplugged the camera, restarted my phone, etc and still no luck. Last couple times tried it, message was format failed.

I inserted another sd into another camera, and would not work first several times, and finally did. I will check later to see if it is recording.

Very frustrating and a lot of money spent on Wyze cards.


Sorry to hear about the SD cards. This article might be useful for others, will add the link here for reference.


Thanks but the problem only showed up after updating the software version. The sd cards worked until then. Is there a way to go back to the previous software version in the cameras?


You can revert camera firmware by following the instructions here:


@offset123 Have you contacted Wyze support about the faulty card(s)? That’s probably your next best course of action.


In follow up to my previous post on Nov. 8.

Did some troubleshooting on the Wyze sd cards.

I purchased 5 cards.

2 cards work, 3 do not work.
I used 2 camsv2 to test.
The 2 cards that work, work in both cams tested.
The 3 cards that do not work, didn’t work in either cam tested.

So it appears to me that the 3 cards are defective.



If the Wyze cards are defective, the only way to get them replaced would be to file a support ticket. You can do so by clicking the Support link at the top of this page. Please be patient as there is currently a bit of a support backlog.


Thanks for your reply.

Much appreciated.



My v2 camera also has SD issues. I tried an off brand 512 GB first then a 32 GB Wyze brand and both freeze the camera and cause it not to connect or only show the live shot for a second. Very frustrating because I want to record!



I would click the Support link at the top of this page and run through the troubleshooting section. If that doesn’t do it, and if you don’t get other help here from the community, file a support ticket, preferably from within the app while the bad camera is connected so that the logs are captured. You might want to submit the ticket right away because there’s somewhat of a backlog. You can always let them know it’s already resolved when they contact you.


I am collecting some info on similar issues. If you still have this issue not solved, can you check something for me? When you format the card in camera, check the “SD card memory available” before and after formatting. Before formatting, do you have a low number (eg. 1.x GB) available out of 29.x GB? The camera may report “formatting complete” but afterwards, it still says 1.x GB available. If the formatting was really successful, it should show 29.x/29.x available (IOW, the card is empty).

If you are seeing the same low available space number after formatting, then I believe your card is damaged and will not be able to be formatted even on a computer. If you want, you can remove the card and try to format it using the tool here:

SD Assoiciation

SD Memory Card Formatter 5.0 for SD/SDHC/SDXC

The SD Memory Card Formatter formats SD Memory Card, SDHCMemory Card and SDXC Memory Card (respectively SD/SDHC/SDXC Cards) complying with the SD File System Specification created by the SD Association (SDA).

I think you will find it report errors and fail to format. In this state, you can copy off what’s still on the card, but cannot format the card or write new data to it.

Let me know if this is what you’re seeing. This is what I’m trying to track down.


Thanks I’ll give it a try.


Ive had that issue a few times. Just took out the sd card and formatted it in my computer then back in the cam.
