Sometimes when I added a camera or upgraded the firmware on my IP Camera I would start to see grey frames, half frames, corrupt frames or dropped frames in Zoneminder. There are three fixes you can try to resolve this issue.
1) This can sometimes be fixed by increasing your SHMMAX and SHMALL as can be seen in this post.
2) If that does not fix your problem try adding ?tcp to the end of your RTSP or FFMPEG stream in zoneminder as can be seen in this post.
3) Another thing you HAVE to make sure frame rate(FPS) on Zoneminder is the same or a little higher than it is set on the camera, this is actually what fixed my corrupt frames after upgrading my camera firmware. I had my camera set to 25fps and zoneminder set to 6 fps, once I set the camera to match or lower (<=) to that of zoneminder settings for that camera, I stopped getting corrupt frames.
