I have two v3 Pro cameras that I “continuously record to Micro SD card on during daylight hours. On one camera when viewing live in the app in iOS or MacOS in portrait mode I can press the SETTINGS gear icon in the upper right window location and I see Micro SD Card in the list of settings. With another v3 Pro camera I do NOT see “Micro SD Card” under SETTINGS, but instead I have to navigate further into “Advanced Settings” to bring up the Micro SD Card “FORMAT” and other controls. The only difference I noticed beyond this is that one camera shows “Name” while the other shows “Device Name” to the left of my camera name in “SETTINGS”. Both cameras are at Plugin Version 3.9.0 and current Firmware 4.58.14.4178 1/2/2026
I am using Samsung Pro Endurance 128GB memory cards with some luck, but I typically have to reformat the SD Card at least once over the winter in each camera to avoid having cameras fail to reboot after an automatic firmware update, and to be able to play continuous recordings from the SD cards. In the past I have not found corrupt file structure on the cards on my laptop, but I do have to remove the SD card to be able to restart the camera which returns to usable after reformatting the SD card on a laptop using the scard dot org SD Card Formatter app.
This topic is primarily about the Wyze APP and why it places the MicroSD Card control in different locations for what should be identical cameras.
That’s very odd, they’re definitely both v3 Pro and one isn’t a regular v3? I mean if they’re the same firmware I guess they must be. That firmware references fixing a bug with microSD, I wonder if one of the cams didn’t update properly or something.
All my cams have the MicroSD card right under settings, not under advanced, but I’m on Android. Maybe try clearing your app cache (both within the app and in your OS).
I’m using the same Samsung cards and I can’t recall the last time I formatted them, definitely over a year ago. But my power is very reliable and I never power off the cam or remove the SD card without doing the “eject” function in the app. A power outage during a write can definitely corrupt a card and require a format.
Next time you have the cards out, try formatting them using the utility from sdcard.org. I use that on every new card, and on the cards in my dash cams (which do seem to get messy every 6 months or so and complain about slow write speed, and that utility solves it). Basically that’s the only way I ever format an SD card or thumb drive.
If you want to totally “refresh” the cards, do a full overwrite format. On a 128GB it will probably take 30-60 mins per card but can cure problems that the quick format can’t.
Both cameras are “Wyze Cam v3 pro”, and to reconfirm this they both have “2.5K” playback quality.
Agreed on sdcard.org tool - which I’ll use when I get back on-site in the spring.
I’m moving to the 256GB cards as that doubles the effective lifetime, but on paper the 128GB 800TBW spec is over a century at compressed 2.5K rates!
Agreed on a possible firmware update issue. I’ll start fresh in the spring and do a firmware update using reformatted cards. I turned off automatic updates for now as I know they can fail. I see I can force a firmware update using an SD Card, but the cam v3 Pro doesn’t have active links for firmware versions.
I have auto updates off on all my cameras and I never do remote firmware on any of my cameras at the cottage, just in case I need to manually interact with them after botched firmware update.
I don’t recall seeing an 800TBW spec on the 128 Samsungs, that seems unlikely, most of their SSDs can’t even do that. The Pro Endurance 128 are the ones I use, and when I calculated it out based on the wyze write speed, it was around 16 years of continuous writes (I forget what the TBW spec was). Reverse engineering that calculation comes out to about 64TBW which seems about right.
Samsung states the 128GB Pro Endurance card is good for 70,080 hours of continuous recording at HD (1920 x 1080) about 8 years. The 256GB Pro endurance is rated at 140,060 hours continuous recording HD (1920 x1080) about 16 years. I have both 128GB and 256GB cards and cams recording in both HD and 2.5K.
Yeah but if you read the fine print, they base that on 3.25MB/s which is much more than the Wyze cams record, so I had calculated out a much higher endurance.
But I guess that is where OP came up with the 800TBW number since that’s what it works out to at 3.25MB. Seems unlikely but I agree, I’ll be happy if they last the 5 year warranty period. Actually I’d prefer they die at like 4.9 years so I get fresh new ones
Flash memory is going to be expensive this year, but I’m well within the 5 years so hopefully wont have to be buying any.
