These are a few methods to attempt to fix a camera with a bad video signal.
- Check the termination switches on the back of the unit (above port 16, only on 8 and 16 Channel x240 machines).
- Change the combfilter settings in vFormat utility (Start -> Programs -> Openeye ->vFormat).
- Check the power connections or line lock settings of the camera.
- Determine whether the camera has a bad video signal on a different port, or if the signal is bad on one port. This can be indicative of a termination switch or combfilter setting versus a bad camera signal or camera power issue.
