store video on Oak-d localy?

CodingArcher

is it possible to store the video recordings on the DepthAI device itself first and then when recordings are complete that it then downloads to a host?

Reason for this is i am trying to connect
3x OAK-D POE
AND
3x OAK-1 POE
from which i am trying to collect all of the video streams (mono and rgb) cameras, thus giving me alot of data stream which is a big botleneck. I do not require a live feed even though it would be nice if that would be possible do advice me of a senario where i can do this.

cheers

Hello CodingArcher,
so the only real solution here would be to save (encoded) video streams on the SD card. POE devices have an SD card slot, but unfortunately we don't have support for it yet. We are thinking to expose SD card support via Script node (which supports running python scripts on the device), since it has file system support. There's no ETA for this support yet, but we hope to have alpha release of this out in the next few weeks.
Thanks, Erik

Yeah i did notice the Sd card slot as i had a sneak peak inside of it 😉

Hmm do you think it is possible to have all 6 devices record simultaneusly without losing frames?

CodingArcher I wasn't sure about it either so I checked as well 😃

Do you mean on the SD card or by streaming all streams to the host and writing it on an SSD there?

If SD card, yes; you could have as many devices as you would want to, since there wouldn't be much/any communication with the host, so there wouldn't be any bottlenecks.
If you meant on the host SSD, that really depends on the frame size - what frame resolutions are you trying to stream? I believe your computer's ethernet can quickly become the bottleneck here.

Hi erik ,
yeah idealy it would be best to have the SD card to store them as a temporarily location before transfering it to the host. I guess i have to wait till you guys give the SD card option aviable in the alpha 😃

I would be looking at high FPS and also good resolution to be able to see minute details.

Cheers,
Markus

CodingArcher makes sense, we will try to push its priority higher. I believe that would work, especially with the help of encoding.
Thanks, Erik
