Hi all , i am using a OAK-FFC-4p with 4 OAK-FFC OV9782 W. To test the setup, i am running : `camera_multiple_outputs 640 480 1 30 CAM_A 640 480 1 30 CAM_B 640 480 1 30 CAM_C 640 480 1 30 CAM_D` with this result, only 1 out of 4 colored and a lot of noise and artifacts : [upl-image-preview uuid=aeafbe77-e456-4d00-810b-01d8f092a1df url=https://discuss.luxonis.com/assets/files/2025-11-22/1763814818-202119-2025-11-22-133043-2560x1600-scrot.png alt={TEXT?}] [upl-image-preview uuid=aa3bba13-8b6c-4bb0-bbba-47b6c000d8cc url=https://discuss.luxonis.com/assets/files/2025-11-22/1763815210-170731-2025-11-22-133950-2490x1513-scrot.png alt={TEXT?}] Even if i write my own code to get all 4 the images i still get the same, 1 camera works kinda well, the other 3 are black and white with black dots.

Bad quality on OAK-FFC 4P with OAK-FFC OV9782 W

Hi all , i am using a OAK-FFC-4p with 4 OAK-FFC OV9782 W.

To test the setup, i am running :
camera_multiple_outputs 640 480 1 30 CAM_A 640 480 1 30 CAM_B 640 480 1 30 CAM_C 640 480 1 30 CAM_D

with this result, only 1 out of 4 colored and a lot of noise and artifacts :

Even if i write my own code to get all 4 the images i still get the same, 1 camera works kinda well, the other 3 are black and white with black dots.

What problem is this ?

Thanks

It seems like the 3 wrong cameras get recognized as the wrong model, maybe the OV9282 which is mono.

The fact that there is no debayering would explain the grid artifacts.

If this is the case, how do i force the cpp sdk v3 to a camera model ?

Hey @StefanoMutti - this is a known OV9782/OV9282 because the sensors have an identic interface and there's no way to know from probing I2C if the camera has the bayer filter or not...
You can set it manually by setSensorType when building node. You can follow this discussion:

Hello @OskarSonc and thanks for the reply.

Indeed i noticed that the sensors where recognized as the wrong one and setting the sensors to color mode makes them owrk properly.

I still noticed that the images are very grainy and disturbed.

Is there something we can do to improve them ?

thanks

Are the images grainy on all sensors on the FFC or only on the B,C,D ports? Can you provide some pictures?

The image is zoomed in.

Thanks

Hm that is really hard to tell from that image, could you send the unzoomed version with some objects?
