Perimeter Protection: Using a deep learning algorithm, Dahua Perimeter Protection technology can accurately detect humans and vehicles. In restricted areas (such as pedestrian and vehicle zone), the number of false alarms of intelligent detection depending on the type of target (e.g. triage, intrusion, fast moving, parking, location and collection detection) is greatly reduced.BLC: The BLC function eliminates the effect that occurs when the camera is pointed towards a strong light source, i.e. when the foreground becomes dark and unreadable. The compensation consists in brightening of the foreground, unfortunately also at the expense of the background, which also becomes brighter. Generally, the function improves image quality.SMART IR: Smart IR ensures a clear and optimally illuminated image even in places with low ambient light. This function allows automatic adjustment of the IR light intensity. This function allows the user to change basic image parameters such as contrast, exposure and brightness. The signal processor continuously analyses the image and reduces the IR illuminator power immediately after detecting overexposure. Thus, the image becomes clearer and the overexposure disappears.
