Thanks to accurate recognition, the system can filter out up to 90% of events causing false alarms, which significantly increases the accuracy and effectiveness of the alarm and contributes to reducing labor costs. Smart Hybrid Light technology Smart Hybrid Light is a series of IP cameras equipped with a dual lighting module. Each camera in this series is equipped with IR illuminators for discreet observation in night mode and additional LED lighting, which is activated at the moment a person or vehicle is detected. Smart mode allows automatic switching between infrared and LED visible light, which guarantees optimal visibility and identification of objects. After the interaction is over, the camera intelligently returns to IR mode, ensuring continuous monitoring while maintaining energy efficiency. ColorVu Technology Hikvision ColorVu technology provides vivid colors 24/7. The F1.0 super aperture collects more light to obtain a brighter image. Advanced sensor technology can significantly improve the use of available light. In a dark scene, the built-in warm supplementary lighting ensures colorful images. Image enhancement features ROI function WDR 120 dB 3D DNR HLC BLC AGC AWB ANR . ROI (Region of Interest) allows you to provide high-quality recording exclusively from the area selected by the user. In others, which are outside the ROI, the camera transmits a lower-quality image or does not transmit it at all. WDR 120 dB improves scene reproduction in the event of large differences in the level of illumination of different parts of this scene. Typical applications for this functionality are glazed passages, building entrances, etc. This technology flawlessly copes with recording images in the presence of large light contrasts, which can so often interfere with the correct operation of the camera. 3D DNR Causes multidimensional filtering of the converter pixels to eliminate noise-related effects during recording due to interference (resulting from, for example, changes in signal strength) and correct color rendering by the camera. HLC automatically detects areas in the frame that are too brightly lit and then reduces their brightness. This allows you to see all the details, such as license plates, which works best at night or in the case of monitoring an underground parking lot. BLC is a technology used in video surveillance systems that improves image quality in difficult lighting conditions, especially in situations where the background is brightly lit and the foreground is underexposed. AGC is an automatic adjustment of the signal gain when necessary. If the signal level is too low, AGC increases its gain, and if it is too high, it reduces the gain to prevent overload. AWB is responsible for automatically adjusting the white balance in the image to ensure natural and faithful color reproduction. It works like this, that analyzes the color of the light in the frame and adjusts its color temperature so that all colors in the image look natural. Thanks to this, regardless of whether the camera is set to daylight, artificial light or another light source, the image will always have natural and faithful color reproduction. ANR image recording on the card in the absence of a connection to the recorder (network failure) and subsequent synchronization. H.265+ compression even less bandwidth and more disk space The HIkvision camera uses H.265+ compression, which allows you to reduce network bandwidth and reduce disk space in the recorder. At the same time, standard compression can be used to maintain compatibility with other systems.
