Event Control - GigE VA Series User Manual

The camera can provide a Strobe Out output signal. The signal goes high when the exposure time for each
frame acquisition begins and goes low when the exposure time ends as shown in Figure 9.35. This signal can be
used as a flash trigger and is also useful when you are operating a system where either the camera or the object
being imaged is movable. Typically, you do not want the camera to move during exposure. You can monitor the
Strobe Out signal to know when exposure is taking place and thus know when to avoid moving the camera.
