**Hi everyone,** I’d like to confirm whether the OAK-4 S camera supports the USB-C interface for both powering the device and data transfer/programming. (Windows 10 OS) And also, possible to achieve 30 fps with full res of video quality? (Providing all the required hardware) Any help would be greatly appreciated. Thanks!

Hey @"Chetan_Barker"#3548 When connected via USB-C, the OAK-4 will enumerate as a standard USB device and can be accessed through ADB (Android Debug Bridge). This is handy for debugging and development, but it **does not support** running DepthAI pipelines or tools like `oakctl`. Also note: the OAK-4 can draw up to 25 W peak, so powering directly from a computer USB port isn’t supported and may cause crashes. The Y-Adapter is also incompatible due to the high power demand — we recommend PoE+ (802.3at, 30 W) injector/switch for stable use. More info here under 4. ADB: https://docs.luxonis.com/hardware/platform/deploy/oak4-deployment-guide/ Thanks, Oskar

Hey @"OskarSonc"#p31386 Thanks for the response. Noted I will try out as per suggestion. How about "And also, possible to achieve 30 fps with full res of video quality? (Providing all the required hardware)" ? Kindly advise. Thanks & Rgds, Chetan

Yep — OAK-4 S uses the IMX586 and supports 48 MP (8000×6000) at up to 30 FPS at the sensor level, but full-res streaming is only practical with on-device encoding.

Full-res streaming is only practical with on-device encoding means? compressed video? Also, to program the camera from host IPC/machine, I can't use ADB right? this is for just debugging purpose only.

@"Chetan_Barker"#p31395 > Full-res streaming is only practical with on-device encoding means? compressed video? Yeah, taking the full resolution and piping it through the integrated videoencoder. Otherwise the 2.5gpbs bandwidth will quickly fill up. You can program the camera, but you **currently** won't be able to run it through USB (to stream images and such). Thanks, Jaka

@"jakaskerl"#p31414 1. USB-C Interface: 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? (Setup will use a USB-C PCIe card with 10 Gbps per port, following the connection guidelines in the OAK web setup documents.) 2. Interfaces & DepthAI: After setting up the USB-C connection, will the DepthAI library automatically detect all available devices and handle firmware and pipeline loading, as described in the documentation? In that case, can we use DepthAI and its pipelines to communicate with the camera in a similar way as with the Ethernet interface? 3. PoE Interface: I’ve come across two different specifications for speed 1 Gbps and 2.5 Gbps. Could you please confirm which one is correct? And also, I was trying to connect camera with static IP address but couldn't connect. Can you please guide me? Facing connection issues when try to connect multiple cameras. I don't want to use DHCP.

@"Chetan_Barker"#p31417 > @"Chetan_Barker"#p31417 USB-C Interface: Yeah, the USB supports up to 10gbps (gen2). You will be able to do that, though keep in mind there is always overhead with USB so the effective numbers will lower. > @"Chetan_Barker"#p31417 After setting up the USB-C connection, will the DepthAI library automatically detect all available devices and handle firmware and pipeline loading, as described in the documentation?

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).. > @"Chetan_Barker"#p31417 I’ve come across two different specifications for speed 1 Gbps and 2.5 Gbps.

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). Thanks, Jaka

@"jakaskerl"#p31432 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"#p31432, so I can't use USB C interface from the host PC to stream video? Please confirm.

@"jakaskerl"#p31432 > @"jakaskerl"#p31432 The devices will be updated to support link-local as well, but for now - ADB into the device and set the IP using agentconfd - (IP should be in the range 169.254.x.x/16). 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?

> @"jakaskerl"#p31432 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?

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.

jakaskerl

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

Possible without internet? If not, I will try to connect and do it

Need internet or is this without internet?

Also, I would like to confirm if the following CAT 6 cable connections are acceptable:

CAT 6: Host PC → Network switch
CAT 6: Switch → Power injector
X-coded M12: Power injector → Camera

Will there be any performance drop when using CAT 6 cables? Do you have any recommendations?

Thanks…..

Chetan_Barker Possible without internet? If not, I will try to connect and do it

It's possible, but you have to use this - Update From Device (keep data).

Chetan_Barker Need internet or is this without internet?

Without internet. But this will do a FULL flash. EDL should work, but it's a bit finicky on older devices because of USBC.

Chetan_Barker Will there be any performance drop when using CAT 6 cables? Do you have any recommendations?

That's fine. No drop should be visible, the bottleneck is the CAT5e cable likely so you won't see a difference.

Thanks,
Jaka

Hi Jaka, I have tried both methods and failed. I have connected internet while doing it.

I have tried this as well "agentconfd update https://luxonisos-rvc4.fra1.digitaloceanspaces.com/OTA/full_update_luxonis_ext4-1.19.1+faee171cd8b76431317459de8a995d406e990cd6.zip"

Any way to stream the high-resolution raw camera frames without putting much load on the host CPU?

Rgds,

I have successfully pushed and updated the OS.

Camera IP was 192.168.55.14
OS update was successful.
Rebooted the camera
IP was empty after reboot. It was not updating the IP address automatically from the PC port or switch.

jakaskerl For OAK4 the only supported outputs seem to be the ones indicated in the error message.

Noted, thanks

Chetan_Barker

I have run the example code snippet from the OAK website, it is throwing error "[166697679] [192.168.30.11] [24197.817] [Camera(0)] [error] Resizer encountered an error: Only supported Camera node output formats are: NV12 (most performant), GRAY8 (very performant), RAW8 (very performant), RGB888i (middle performant), BGR888i (worst performant)"

Chetan_Barker
RAW as in unbayered? Host cpu shouldn't be "too" bothered by the frames, but it depends what you are doing with them.

As for the error - as suggested - you are trying to request a planar RGB output RGB888p, and it is not supported.

Thanks,
Jaka

Even after a reboot? A new OS is public now (1.20.5), in case you wish to update.

Thanks,
Jaka

Chetan_Barker

jakaskerl

Yes, even after reboot.

I’ve updated the device to OS version 1.20.5, but the issue persists. After rebooting, the device does not automatically obtain an IP address from the network switch. I have to manually assign the static IP address again using adb.

And also, after some time static IP address will be reset and empty.

DWrecker

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

Hi @jakaskerl , first of all, I want to say the OAK-4 looks fantastic — its capabilities, image quality, and overall design are truly impressive. Amazing work by the team!

I noticed earlier mentions that USB streaming support for the OAK-4 was expected around November, but after checking the release notes it seems it hasn’t been released yet.

Could we get an update on the expected release date for this feature?

AlexHendren

@jakaskerl Can you please clarify the status of streaming over USB? Is this related to the v1.21.1 release notes?

Added Luxonis USB interfaces

Interface 3: Luxonis DepthAI Gate

Interface 4: Luxonis DepthAI Device

AlexHendren
End of February is the timeline now. There were issues with USB integration so it is taking longer than expected.

Thanks,
Jaka
