WDR, BLC, HLC and Low-Light CCTV

Understand common image technologies for entrances, gates, windows and difficult lighting conditions.

WDR

Wide Dynamic Range helps balance very bright and dark parts of the same scene.

BLC and HLC

Backlight compensation can improve subjects against bright backgrounds; highlight compensation can help with strong light sources.

Low-light quality

Megapixels alone do not determine night performance. Sensor, lens, illumination and processing all matter.

Test the real scene

Tune and test the actual camera position when difficult lighting occurs.
