The device comes from the Hikvision Smart Hybrid Light camera series and is equipped with the well-known AcuSense technology. The camera can operate in three different night modes and offers a black and white image using an IR diode, color in the case of using a visible light LED or in SMART mode, which automatically changes the IR mode to LED upon detection of a person or vehicle. AcuSense technology AcuSense technology, based on artificial intelligence (deep learning) algorithms, allows for the classification of targets and objects under surveillance, which significantly increases the accuracy of alarms and allows for easier and more efficient search for video recordings. 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. Image enhancement functions: ROI function WDR 120 dB 3D DNR HLC BLC AGC AWB . ROI (Region of Interest) allows you to provide high-quality recording exclusively from the user-selected area. In others, which are outside the ROI, the camera transmits an image of poorer quality or does not transmit it at all. WDR 120 dB improves the reproduction of the scene 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 perfectly copes with recording images in the presence of large light contrasts, which can so often disrupt the correct operation of the camera. 3D DNR Causes multidimensional filtering of the pixels of the converter in order to eliminate the effects related to noise during recording, which arose due to interference (resulting, for example, from changes in signal strength) and the 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, for example, license plates of cars, 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 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 by analyzing the color of the light in the frame and adjusting 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. 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 disk space in the recorder. At the same time, standard compression can be used to maintain compatibility with other systems H.264. PoE technology Power over Ethernet (PoE) is a solution developed for quick and uncomplicated installation of network devices.
