The DS-2CD2387G2H-LIU is a Hikvision-branded IP ceiling camera with hybrid illuminator, featuring ColorVu and AcuSense (2nd gen) technology. With ColorVu technology, the camera can capture images at night in color mode while retaining important identification details. 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 intelligent mode in which when an object such as a person or vehicle is detected, the LED illumination turns on, allowing observation in color mode, while when the object disappears, the camera switches back to IR mode.

The camera is equipped with a 1/1.8" Progressive Scan CMOS sensor with a resolution of 8 MP featuring very high sensitivity and ability to capture images in low light conditions. The camera features an ultra-bright F1.0 lens with a focal length of 2.8 mm, which enables viewing angles of 108.8°. Built-in microphone enables sound recording. The IR infrared and LED white light illuminator with a range of up to 40 m ensures proper observation in night conditions. 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. Additional functions to help improve image quality including: AGC, 3D-DNR, WDR (130 dB), BLC, HLC and built-in image analytics (VCA) based on a deep learning algorithm, allows you to use the camera for advanced projects. 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 secena illumination: classic infrared, white LED light and smart mode. In 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 camera is part of the EasyIP 4.0 series, which currently includes camera models equipped with IR, LED, hybrid illuminators, Motion Detection 2.0 (human and vehicle filter), ColorVu technology and AcuSense (2nd gen). AcuSense is based on deep learning algorithms, enabling classification of targets based on human and vehicle silhouette using intelligent VCA analysis such as detection of intrusion, line crossing, entry and exit from an area. With accurate recognition, the system can filter out up to 90% of false alarm events (e.g. animals, rain, cobwebs, moving leaves, etc.) which significantly increases the accuracy and efficiency of alarming and contributes to lower labor costs. With the ability to display a color image in all conditions, ColorVu cameras allow you to record all the details in the monitored scene.

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. Therefore, hard drives with a halved capacity can be used, or recordings can be stored 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.

A mobile application Hik-Connect is dedicated to operate Hikvision devices using cell phones with the operating system Android or iOS. It can be used to remotely view live video from DVR, NVR, network cameras, video intercoms using Wi-Fi, 2G or 3G networks as well as to view recorded video. Video intercoms can be operated with the application which additionally allows for remote opening of electric doors, receiving notifications and transferring calls from the entrance panel to the phone in the absence of the resident. The application supports connectivity via IP and the P2P cloud. Hik-Connect is also the name of a cloud-based service that allows access to devices in the absence of an external IP address.

The degree of protection (IK rating) against external mechanical impacts offered by electrical equipment housing is defined in the EN 62262 standard. The EN 62262:2003 standard also specifies the conditions of the testing procedure.

The camera has an IK10 rating.

SADP (Search Active Device Protocol) is a free, easy-to-use utility designed to search for Hikvision IP cameras and DVRs/NVRs in the local network. The network device search tool can also be used to modify device network parameters, e.g. to change or recover default passwords. Detailed information on the software, its use and password recovery (par. 8) can be found in the following article: SADP application - LAN tool for organizing CCTV systems based on Hikvision devices.
