The v4 specs show that the cam can support up to a 256K SD card, but the FAQs state that it can support up to a 512K SD card. Does anyone know which is accurate? Also, do you know approximately how many days of 24/7 recording can be stored on each size card? First post. Thank you all for your he…

The 256 GB cards have 238 GB of usable space and last about 3 weeks on my V4 cams with continuous 24/7recording. All the cams record a different amount during the same period but 21 days is the average.

One more thing to consider is Wyze Cloud Event Videos auto delete after 14 days. It would be tedious to try to find SD card video older than 14 days unless you knew the exact day and time you want to view.

Welcome to the Forum, @stephenmjoseph ! :wave: When Cam v4 launched, the marketing and product page indicated support for microSD cards up to 512 GB (I think that may have been the first official mention of support for that size of card for a Wyze Cam), but that has since been changed to 256 GB for…

I wouldn’t be surprised if 512GB or even 1TB worked fine. But given the cost of memory these days, it is probably way overkill. Much more important to buy a good brand, endurance rated card. My 128GB Sandisk Pro Endurance cards give me like 9-11 days (depending how much motion, what time of year/…

I just bought 3 different 512 gb cards from China. One was supposed to be really good one. Not one worked. Tried everything. They were $10 each. But I really don’t think 512s work in them cause it says up to 256 g. On the site. So I just ordered one 256 and one 128 to try.

They can handle 512 fine. As @crease said, they may be counterfeit. Only buy name brand cards from reputable sellers (shipped from/sold by amazon, not 3rd party for example, or direct from the manufacturer). Try to stick with higher end brands like Samsung or Sandisk, or at least mid range ones l…

[IMG_5504] Ya probably a scam but they look really good. I’m trying this one and a 128 gig $7. lol worth a try anyway. If not I’ll buy a reasonable priced name brand. Like a 64 gig Amazon I’ve had two 32 gigs ones in my older Wyze cams for a quite a few years. Just ones I had laying around. Ma…

Lenovo doesn’t make (or have their own white-label brand) SD cards so those are probably from Ali and are re-labeled from some cheap brand. So test them fully and don’t use them for any critical data.

If anyone is buying non-name brand SD cards, it is wise to check the card with this freeware program called ValiDrive. https://www.grc.com/validrive.htm

ValiDrive can only tell you if you bought say a 256GB card but it really only has about half of that storage.
