Noise reduction system - 3D NR
Noise reduction system allows the image clarity at variable levels of signal strength. In practice, this function protects against the occurrence of the so-called record. smearing effect and allows you to keep detailed and crystal clear video.

Digital extended dynamic range - DWDR
Software-based technique, which allows for easier identification of objects in dark areas of an image by the use of gamma correction (conserving natural shadows and lighting - as opposed to a simple change in brightness or contrast). DWDR function is a cheaper and inferior variant of the WDR.

Smart IR
Smart IR allows you to change the basic image parameters, such as exposure, contrast or brightness. The signal processor analyzes the image in real time and immediately after detecting the X-rays reduces power infrared illuminator. Thus, the picture becomes clearer, and x-rays disappear.

Backlight compensation - BLC
This function enables the elimination of the effect arising when the camera is pointing towards a strong light source, that is, when the first plan becomes dark and legible. Compensation is to brighten the foreground, unfortunately, also at the expense of the background that it becomes brighter. Generally, the function improves image quality.

High light compensation - HLC
The algorithm detects image points, which are strongly illuminated, and then allowing them to mask the effective observation. HLC is extremely useful for observation of underground car parks. It lets you read the license plate numbers, which are covered "bright spots" of the headlights

Function of  the region of interest - RoI
The Region of Interest allows you to increase the recording quality in parts of the observed scene indicated by the user. With the real ROI it is economical registration records and saves the total volume of video files while maintaining the original image quality in priority areas.

Privacy masks

Effective video surveillance systems is also a smart selective recording video. Using the properties of the  camera function of the privacy zones  real will customize the way the observation system to the specific spatial and security requirements of the particular installation location. Thanks to the privacy masks can be freely designate parts of the image that will be excluded from video surveillance. Full control monitoring system will provide valuable archive of video material with due care for the realization of the right to privacy of third parties.
