Cameră IP 4 MP bullet Hikvision DS-2CD1047G2H-LIU AcuSense 2.8mm IR 30m.

DS-2CD1047G2H-LIU is a Hikvision-branded IP compact camera with hybrid illuminator, featuring ColorVu and motion detection 2.0 technology. The EasyIP Lite series cameras have the basic, most commonly used functions, so they are ideal for most systems where stable and trouble-free operation is required. With ColorVu technology, the camera can capture images at night in color mode while retaining important identification details. Motion detection 2.0 function eliminates false alarms by filtering out human/vehicle type objects. The camera has a 1/3" CMOS sensor with a resolution of 4 MP and a hybrid illuminator with a range of up to 30 m, ensuring proper visibility in the absence of light. Thanks to the IR and LED illuminator in a single housing, it is possible to select one of three low-light modes: IR, white light LED or smart mode. The 2.8 mm fixed focal length lens allows for 115° observation. Built-in microphone enables audio recording. Support for the legacy and latest H.265(+) compression methods allows for the archiving time of recordings to be extended while maintaining excellent image quality and backward compatibility. The IP67 rated housing protects the inside electronic components from adverse weather conditions. The camera can be powered conventionally with 12 VDC or through PoE (compliant with the 802.802.3af standard).

Hikvision has introduced Smart Hybrid Light cameras, which combine the advantages of traditional cameras and ColorVu series cameras. The traditional cameras have an IR illuminator that illuminates the scene, allowing them to record images at night, at the expense of losing details in the form of colors. ColorVu cameras, can record color images around the clock, but the use of white light illumination is not always expected. To meet these requirements, Hikvision is introducing smart hybrid cameras with ColorVu technology, equipped with three modes of secene illumination: classic infrared, white LED light and smart mode. In the smart mode, the camera triggers white 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. What mode the camera will operate in is decided by the user.

The ColorVu Lite camera with hybrid IR illuminator has a large aperture F1.0 lens, which provides 4 times more light to the sensor compared to a traditional camera with an F2.0 aperture lens.

The camera supports motion detection 2.0, which filters detected objects for human/vehicle silhouette. 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. With Motion Detection 2.0, recordings stored on an NVR supporting this technology can be quickly searched for a human or vehicle silhouette without having to review hours of footage.

Compression 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 (HEVC - High Efficiency Video Coding) is currently the most efficient compression method. Compared to its predecessor (H.264), it reduces the data stream and the demand for disk capacity by half. This allows you to use hard drives with half the capacity or store recordings for twice as long. Its improved version H.265 + has been optimized for use in CCTV monitoring systems. They allow for further reduction of data streams.

Hikvision devices can be operated via mobile phones with Android or iOS using the dedicated Hik-Connect mobile application. It can be used to remotely view live video from DVR, NVR, IP cameras, door entry systems using Wi-Fi, 2G or 3G networks and also to view recorded videos. Operating video intercoms with the application provides also remote opening of the electric strike, receiving notifications and transferring calls from the entrance panel to the phone in the absence of the subscriber. The application allows connectivity via IP addresses and via P2P cloud. Hik-Connect is also the name of the cloud service that provides access to devices in the absence of an external IP address.
