Balance Light Control (BLC)
Balance Light Control (BLC) is a method to compensate for bright spots in the picture. 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 a person who is moving from bright daylight into artificial daylight. This could result in the subject becoming an unidentifiable silhouette.
Bandwidth
Bandwidth indicates the complete range of frequencies over which a circuit or electronic system can function with minimal signal loss. In effect, bandwidth indicates the amount of information and its complexity which can be carried over a signal. More complex information requires more bandwidth for an effective signal. (i.e. color video bandwidth is greater than monochrome video bandwidth, which is greater than the bandwidth for one channel of audio).
