We have 6 C60 in the same building, but one of them could not adjust the camera. I connected the camera to other c60, it was the same issue. Do i need to replace the camera since all c60 are using the same firmware or is there other option i can do at the moment?
Since you took the camera in question and tried it with another C60 and it didn't work with it either, it sounds as if the camera is faulty. The only other thing I'd make sure is to check the camera control cable. With the camera connected to a known working codec and camera control cable, check the camera status in the web interface to see if it's detected etc. If it still fails to work and or the camera isn't detected by the codec, you should contact TAC to request a replacement if the camera is covered on an active support contract.
