No worries. My 128GB SD cards last for:
- Averages almost exactly 14 days in a V2
- Averages just over 11 days in a V3 (on my most recent test; though it only shows up to like 119GB available on a 128GB card)
A good rule of thumb I’ve found in my experiments is that a V2 seems to use just over 9GB/day, and V3’s use just over 10GB/day (in earlier tests…it was like 10.3 or something…so 128GB cards give about 119GB usable, and 10.3GB/day ended up being close to 11.5 days - just verified on my front V3 today). The difference is presumably due to the higher FPS rate on the V3 (from 15FPS on the V2 to 20FPS on the V3 during daylight recording, which is a 30% upgrade, so I would’ve expected it to use roughly 12GB/day, but maybe it just has better compression or something, IDK, they do seem to function a little differently depending on how much action is on-screen, though I am not sure why.
Those were both tested under the same conditions (no Night Vision). If you have it set to automatic, and they switch to nightvision with IR and lower FPS at night, then in theory your card could last different lengths of time depending on some of those factors.
Additionally you can set it up to only record events instead of continuous and it should last A LOT longer, depending on your sensitivity settings, detection zone, activity in the area, when the activity takes place (night/day) etc.
So there are a lot of things that can make a difference in how long an SD card lasts and how much it records, and those numbers can change over time as Wyze gives updates, but that is what I found the last time I tested my V2’s and V3’s under similar conditions a few months ago…Wyze has done some firmware upgrades since then, and while I don’t think those times have changed much, it is always possible.
And incidentally, you can sometimes just throw a card in and it will work, but sometimes it will go in and out of functionality if it isn’t set to FAT32…so it may seem like it’s working, then go out and not record some events, and that sucks. Best to make sure it works right basically all the time.
Hope that helps
