I followed all steps including different SD cards but I keep getting the message “SD card not found”. I purchased the Wyze Pro Battery 3 weeks ago. Any suggestions?
Thanks
Can you clarify which camera - the battery cam pro?
If no SD cards work in it, it may just be defective, and probably makes sense to exchange it. Did you format the cards before trying them - my preference is to use the formatter from sdcard.org as it will remove any special formatting that some other devices can put on cards.
Welcome to the Forum, @alan69700! 
What did Support say when you contacted them? If your Battery Cam Pro isn’t recognizing cards after following their troubleshooting recommendations, then they might offer to replace it since it’s a new purchase for you.
I have v3 cameras on Cam Plus Lite too. I get the error “Microsd card not found” when trying to view the SD card from the Events screen using App version 2.50.
I can view the problem v3 SD card from the Events screen using App version 3.10.6.753.
What App version are you using?
I don’t know if viewing from Events while using a Cam Plus Lite subscription is part of the issue or not, but Wyze has been soliciting user data in this topic for a while now:
You might want to take a look at that if you haven’t already read it. I think @StevenA’s app version question is a good one, too. 
Bear in mind if you want to continue using the 2.5 app you’ll need to disable firmware updates and probably downgrade if you’re running the latest one.
Though I’m not sure what extra step in viewing events you’re referring to. I use micro SD card and just use the forward and back buttons to jump between events. Does that not work with cloud clips?
Just wondering… which firmware version came loaded on your new Cam v3 s?
Keep in mind Wyze requires app version 3.8.5 or above to use Cam v3 firmware AFTER 4.36.14.3497.
I am still on 4.36.14.3497 and have one device on App 3.10. I have been using App version 2.50 for so long is why I prefer the user interface.
When stable new v3 firmware is released I plan on moving all of my devices to App version 3.xx at that time.
Wyze app Home > your Cam v3 > wait for live stream > Settings (gear icon upper right) > Device Info > Firmware Version
Your choice of 32-bit Wyze app is not compatible with latest firmware updates that reportedly address your issues. Wyze cannot update and publish 32-bit app versions due to Google and Apple restrictions. I’d suggest updating to the latest 64-bit app which will also allow you to update your v3 cams’ firmware to the latest version. If you choose not to take that path, you’ll need to downgrade (flash) your cams to older firmware. 32-bit app support ended 2 years ago.
Perhaps the older cameras formatted the older cards differently, or some setting/bug only exists if the card was inserted/formatted after a certain firmware edition.
Given the oddities and inconsistencies of this bug, not sure any of us can figure out what the issue or explanation is. But you have to realize that the 2.5 app is gradually losing functionality and is going to give you more and more problems.
I realize that’s speculation, and I think it’s an interesting idea. One of my observations with this problem on Cam Pan v3 (apologies to @alan69700 for the diversion from battery-cam-pro) has always been that the Cam where I’ve had consistent issues with microSD card recognition, recording, and playback is the device with the more recent Activation Date. After reading your comment, I do wonder if Cam Pan v3 firmware released after a certain date writes something weird to an inserted microSD card that becomes problematic. The microSD card in my older Cam Pan v3 has been there since I set it up, and I’ve never had a compelling reason to reformat it. Now your comment makes me wonder if trying an in-Cam reformat (or doing something like ejecting and re-inserting the card) would hose that one, but I’m not curious enough to risk it. 
Not all Cam v3s are the same. Same goes for a lot of cam models and not just Wyze cams. The older the model of any electronics still being sold, the more likely some board level component required a change due to unavailability of original component.
You could update your app and the firmware on one problem cam and retest the one cam. If it doesn’t prove fruitful, delete app, reinstall 2.50.9.512 and flash your problem cam back. Keep in mind that if you try that test with the latest app, you may not be able to access your other Cam v3s unless you also update those to the latest firmware. And if you do that and then determine that you can’t live with the 3.11.0.758 app and want to go back, you’ll have a lot of cams to reflash.
Since it seems to persist after a format with sd card formatter, I suspect maybe something gets saved in the cam itself or even in the cloud. Some bad index of the card or something, saved in the tiny bit of cache that the SD controller has? As you say, total speculation (heck I wouldn’t even give it that much credit, more like guesswork).
Have you tested the firmware and software that came out today (or the betas previously), did that solve it?
Those are good questions, and I have not. I got tired of trying to get the microSD card issues addressed for that one Cam Pan v3 months ago and so haven’t prioritized that problem, as I’ve had plenty of other things to keep me busy. Plus I had the RTSP β firmware installed on that Cam for a few months—before that was included in the mainstream production firmware channel—so that Cam’s been primarily for test use.
I saw the new Android app offered to me earlier in Google Play Store with a date of 16 March 2026, and then I saw the Wyze News announcement publish a while later, but I haven’t yet updated that, either, so the newest production app I’m currently running is 3.10.6.753 (which, as you noted, does not have the Automatic Update toggle for Cam OG). I’ll have to update that prior to applying some firmware updates, and I’ll probably watch and wait at least a few days to see how that’s shaking out for other users.
That’s a good point, because I have done --overwrite formats with that tool and the Cam still had card problems after that. I should’ve considered that before posting earlier. It’s such a weird problem. I hope they’re making some progress with it.
Lol Arlo is crap. Not sure what reviews you’re looking at, but they’re obviously sponsored, which also explains why other brands might be excluded.
I would have gotten the v4 cams if you liked the v3s. the OGs are fine but the v4 is a better cam.
They identified the SD problem and fixed it for many users with the latest firmware and app, but it appears you are not willing to use that firmware and app that fix it……
V4’s and the OG cameras that @AAcustomer ordered are not compatible with cam plus light. I highly suspect @AAcustomer is not going to be happy with his new cameras.
V3’s can still be found on Amazon for nearly $40. Worth it if you want to use what was originally promised to work FOREVER. Of course that is ancient WYZE history at this point.
Correct, no cameras after the v3 are compatible with cam plus light. Hence suggesting the v4 over the OG as neither one has that benefit.
But if they aren’t willing to use the 3.x app none of the cams are going to work for very long, at least not if they have current firmware.
