Understanding OAK 4 S camera capabilities

Chetan_Barker

This was my question to one of your colleagues,

"It’s mentioned that the USB interface supports up to 10 Gbps. Does this mean that from the host IPC I can achieve video transfer speeds of up to 10 Gbps from the camera?"

Answer:

Yes and no. Our newest devices, the OAK-4 / RVC4, do support up to 10 Gbps speeds. However, with the current DepthAI implementation and OAK-4 / RVC4 devices, we do not support video streaming directly through USB; it is currently only available via Ethernet/PoE+. We are planning to add USB video stream support later this year.

jakaskerl, so I can't use USB C interface from the host PC to stream video? Please confirm.

Hi @Chetan_Barker

Chetan_Barker so I can't use USB C interface from the host PC to stream video? Please confirm.

You will be able to use it in November. It's not ready yet. Note the "future tense" used in my replies.

Chetan_Barker Is there any other way then connect USB C and getting ADB into device? Bcz, when carrying the initial setup of camera during blue light flashing, there is an option for static IP setup. I have used that, and it was unsuccessful. May I know this option I can't use or am I doing it wrong?

You can do a local setup (https://setup.luxonis.com) and manually set the IP there. Then scan the QR code.

Thanks,
Jaka

jakaskerl The devices will be updated to support link-local as well, but for now - ADB into the device and set the IP using agentconfd - https://docs.luxonis.com/hardware/platform/deploy/oak4-deployment-guide/#OAK4%20Getting%20Started-Advanced (IP should be in the range 169.254.x.x/16).

jakaskerl USB will likely support streaming, but I would assume it won't support visualizer (device-side webserver) unless it is also connected to the internet (ETH)..

Can you elaborate this? I can't use USB C for streaming you mean?

this is not working if I use static IP address option. It is flashing yellow light quite long and after that to red

You can do touch /etc/resolv.conf and then retry. It should work offline as well.

jakaskerl typo

Still doesn't work.

Also, I have tried to update OS to 1.19.x like you mentioned in our call (Emage Vision). It shows no firmware updates available

You need to be in root mode first - that is why you get permission denied.

oakctl adb root
oakctl adb shell

For unreleased versions:

ENV=STG oakctl device update

Thanks,
Jaka

Chetan_Barker

jakaskerl oakctl adb root
oakctl adb shell

This worked for me. Thank you.

jakaskerl ENV=STG oakctl device update

Shows not recognized as above

jakaskerl

Chetan_Barker
Ah windows. To set the environment variable there, you can do set ENV=STG. Then run the oakctl command again.

Thanks,
Jaka

I have tried, but update failed.

Chetan_Barker
Any chance you can plug the device into internet and try that again?

The update currently tries to pull the file inside the device - the fix is in the making. oakctl device flash -s with that environment variable should work. It will boot the device into EDL mode and then you can reflash it.

Thanks for the patience,
Jaka
