Hi In reference to the specs mentioned on the [OAK-D S2 PoE page](https://shop.luxonis.com/products/oak-d-s2-poe?variant=43146876551391) it shows that it can run at 30 FPS at a 4K resolution. However, with even the simplest of script where I just have the camera and the output node to get an 4K image at its full FOV gives me just 4.5 FPS. I tested this with the [RGB Video example](https://docs.luxonis.com/software/depthai/examples/rgb_video/) as well with 4K image with a full FOV of 3840 x 2160 and I see I just get a max of 4.5 FPS on an average.

Thanks & Regards Yishu

Very low FPS for 4K frames

It's most likely a bandwidth issue. POE is limited to 1Gbps which is quickly saturated on 4K frames. The S2-POE page showing 4K 30 means the device is able to process frames at that rate, not necessarily display them, because that is a limitation of the network and the ETH controller on the device.

Some calculations
