You can reduce the number of snaps taken by WebCam Monitor. To do so:
On the Monitor menu, click Settings.
Select the Take Snap alert.
Under the General tab, reduce the number of snaps.
You can also increase the snap rate so that WebCam Monitor takes snaps at larger frame intervals. To do so:
On the Monitor menu, click Settings.
Select the Take Snap alert.
Under the Output tab, increase the snap rate in "Take snap after every frame" box.
If you are monitoring bright areas then you can also turn-off some of your camera-specific properties like the Backlight Compensation. To change these settings, point to the tools menu and click Camera Properties.
