Dahua camera accepts 128G micro SD card

[dana2]

The camera claims to accept "up to 128 gigs" micro SD card. Is this a hard and fast number (strictly enforced), or may I also use a micro SD card of 256 gigs?

Thanks!

Also, are there any requirements for speed (i.e. class)

The Samsung Evo plus has proven to be a good choice. No idea on the 256gb working.

Yeah, I was thinking about exactly the same brand/card. Hmmm, I have a 256gb in my cell, I guess I'm going to give it a try and see if it is working.

I’ve got two cams with 200gb in them. They recognised ~180gb on the web interface. So seems fine by me.

Yep, I confirm, recognizes my Samsung Evo Plus of 256gb.

I wanted to revive this thread because it helped me in selecting 256GB micro sd cards for 3 Dahua IPC-HFW2831T-ZS cameras I'm setting up

IPC-HFW2831T-ZS says its max is 128GB, but I've seen this with motherboards where the largest DIMM size when they're released is smaller than what they'll actually accept

So an actual test is very helpful. If the 256GB card doesn't work I'll just run to best buy and get some 128GBs.

Here's the 256GB I ordered (since samsung EVOs jumped to $45/ea!):

Silicon Power makes good SSDs so hopefully their sd cards are good, too. 5-yr warranty helps relieve skepticism.

Will report back with results

Edit: I've tested these 256GB micro-sd cards w/ the IPC-HFW2831T-ZS for over a week, and they work great. Pretty snappy for an sd card. Record worked immediately on insertion, didn't even require a format. Let's see how they hold up, they have a 5yr warranty, but they're up 18 ft in the air, so fingers definitely crossed.

i only ever use class 10 or higher for video / photo recording applications

Those are UHS-3 V30. Class 10 is one square down in the infographic on the SD card developer's spec page: Speed Class - SD Association

Should be fine.

4k IPC VBR rarely exceeded even 6-7 Mbps, i've had no lost data in my IPC-HFW2831T-ZS-S2 VBR writing to class 10 SDXC....and i did say, class 10 or higher....

Great, good to know, thanks
