The DS-2CD2043G2-LI2U is a Hikvision IP tubular camera equipped with a hybrid illuminator and AcuSense technology. The AcuSense technology increases the effectiveness of the surveillance system by eliminating false and nuisance alarms through human/vehicle object filtering. The use of IR and LED illuminators in a single camera allows it to operate in several modes – classic IR, white LED light and smart mode, in which when an object such as a person or vehicle is detected, LED illumination is switched on, allowing observation in color mode. After the object disappears, the camera switches back to IR mode.The camera is fitted with a 1/2.9" sensor Progressive Scan CMOS sensor with a resolution of 4 Mpix and a hybrid illuminator with a range of up to 40 m, ensuring clear visibility in the absence of lighting. It features a fixed-focal-length lens of 2.8 mm and a field of view of 104°. Two built-in microphones allow for audio recording. Support for both older and the latest H.265(+) compression methods enables extended recording storage time whilst maintaining excellent image quality and backward compatibility. Additional features designed to enhance image quality, such as AGC, 3D-DNR, WDR (120 dB), BLC, HLC and built-in video analytics (VCA), enable the camera to be used for more advanced projects. The high-grade IP67 rated housing protects the electronics from adverse weather conditions. The camera can be powered conventionally via DC 12 V or via PoE (compliant with the 802.3af standard).

How the illumination is used is decided by the user by selecting one of three modes- classic IR, white LED light and smart mode. The classic IR mode uses IR illumination in nighttime conditions or when the illumination level is too low. In white light mode, LED illumination is used instead of IR. In smart mode, the camera triggers the LED light when it detects a human or vehicle silhouette, providing a color image. Once the object leaves the detection zone, the camera switches back to IR mode. In addition to illuminating the scene to provide a color image, the LED light has the additional function of deterring an intruder.When there is no person or vehicle on the scene, the camera uses IR modeWhen a person or vehicle appears on the scene, the camera turns on the LED illumination and switches to colour modeWhen a person or vehicle leaves the scene, the camera will switch back to IR modeEasyIP 2.0 Plus (AcuSense)This camera is part of the EasyIP 2.0 Plus series with AcuSense technology, which is based on Deep Learning algorithms. With AcuSense, the camera is able to classify detected human and vehicle objects and filter out all false alarms (e.g. animals, rain, cobwebs, moving leaves etc.) with an efficiency up to 98%. This improves the entire monitoring system performance, and the end user only receives information about alarms that meet the criteria. If the filter is not activated for a given event, the camera will detect all objects, as it was the case with previous solutions.False alarm filtering in all channels and quick object search.

This improves the performance of the entire system and reduces the number of false alarms that reach the user. Once the filter is turned off, detection can continue as before, detecting all objects.Motion detection 2.0H.265 (+) compressionCompression is a very important parameter proving the device advancement. The better the compression, the lower the bandwidth requirement with the same subjective quality. H.265
