No Problems With Back Light

Exposure zones instead of back light, most cameras with mechanical auto iris more or less shut down when they are confronted with backlight. Unfortunately, as a result, the darker areas become even darker and faces unrecognizable. Frequent attempts are made to brighten the image electronically using a backlight function, but the results are unsatisfactory since the auto iris lense is closed.

These cameras have a completely different approach to solving the problem. The CMOS sensors used in the cameras need no mechanical auto iris. Instead, they expose electronically from 1/8000th of a second to 1 second. This means that the cameras have no moving shutter parts that fail or freeze during winter. Without the auto iris, the camera can electronically choose what to see. To do so, exposure windows are easily configured and they inform the automatic exposure control which areas of the image to lighten up.
