Backlight Compensation
It is also important to consider whether there are bright spots in the picture such as
car headlights which can make identification of the vehicle registration or model
impossible.
This can also be a major problem where it is necessary to identify persons who
are moving from bright daylight into artificial light. Very often this will result in the
subject becoming an unidentifiable silhouette. The problem is exacerbated where
bright spots in the images cause vertical smearing.
The answer is to specify a camera which has effective backlight compensation.
This can be operated automatically by Smart Control within the camera or, where
the position of the subject is pre-determined, can be pre-selected.
It is helpful to be able to see how effective the backlight compensation is before
making final camera selection.
