Modern CCTV cameras have BLC, HLC, and WDR features to improve image quality for better results.

Closed-circuit television, or CCTV, cameras frequently have a number of features to improve image quality and adjust to varied lighting conditions. These characteristics include:

The Backlight Compensation (BLC) feature modifies the overall exposure of the picture to suitably expose subjects that are in front of bright light sources, such as headlights, artificial lights, or windows. It assists in avoiding the appearance of subjects as silhouettes against a bright background.

Highlight Compensation, or HLC: Like BLC, HLC is made to handle bright light sources in the image. In order to avoid overexposure and preserve information in certain regions while maintaining the appropriate exposure for the remainder of the image, it lessens the intensity of bright spots.

Wide Dynamic Range, or WDR, is a sophisticated function that enables the camera to simultaneously record information in extremely bright and extremely dark regions of the picture. This is accomplished by taking several exposures of the same scene, modifying the exposure in various areas of the picture, and then merging the results to produce a single, well-exposed picture. Scenes with great contrast, including parking lots, entrances/exits, or places with intense illumination, are especially good candidates for WDR.

Together, these characteristics enhance the camera's ability to take precise, crisp pictures in a variety of lighting situations, preventing the loss of crucial information from overexposure or underexposure.
