CCTV streaming has distortion

I am streaming from 4 CCTVs to my device and one camera has bad noises.
I used gstreamer to stream.
Three CCTVs are ok, but one has bad noises.
That CCTV has also been streamed to NVR from mainstream and at display it is fine.
My device is streaming from substream and image has a lot of noises.
How can I solve and what could be reason?
