This parameter, along with VsyncEdge, declares the attributes of the frame synchronization signal sensed from the camera feeding the channel.

It applies to analog area-scan cameras that deliver a separate vertical synchronization pulse used by the frame grabber to monitor the camera timing (digital synchronization mode).

It also applies to digital area-scan cameras that always deliver a separate vertical synchronization pulse used by the frame grabber to monitor the camera timing.

This parameter is meaningless for line-scan cameras.

In the case of digital cameras, the signal described by VsyncCtl is often called Frame Valid or FVAL.
