Configuring the Camera AW00101507000

62 Basler IP Fixed Dome Cameras

Using the Flash Window (Rolling Shutter)

To provide the best-possible lighting conditions, apply the additional lighting during the "flash

window" of each frame. The flash window is the period of time during a frame acquisition when all

of the lines in the sensor are being exposed. See Figure 7.

Fig. 7: Flash Window

When the Strobe Mode parameter is set to "Flash Window", the camera sends a signal on the digital

output port that can be used to trigger a strobe pulse (= flash) in order to provide additional lighting.

This signal is called the flash window signal. See Figure 8.
