grey video but has clock ticking?

[dony71]

I have grey video in BW or red video in color, but can see clock ticking
I'm using zmodopipe
What's wrong in setting ? Anybody help?

May be that you do not have the resolution set right. The WxH settings in ZM need to match the camera output exactly.
Please tell us a bit more about your system (Linux version) and camera.

Camera is zmodo DVR so it's buffered using zmodopipe under linux
