The Hikvision DS-2CD2423G0-IW K1718 camera is dedicated for anyone who wants to build cost-effective IP CCTV system. The camera has been equipped with high quality 2 MP CMOS sensor providing perfect video even in low-light conditions and without visible lighting (in IR mode, thanks to the built-in IR illuminator with range up to 10 m, made in EXIR technology). Its intelligent analysis functions include face detection, line crossing detection and detection of intrusion into a defined area. The user can also set up a region of interest (ROI) - part of the image with increased video transmission parameters. The camera has been designed for indoor applications. It can be powered conventionally with 12 VDC or using PoE option (compatibility with 802.3af).

The built-in microphone and speaker of the camera can be used for videoconferencing. The minimum requirements for the other side include a suitable PC with microphone and speaker/headphones, capable of receiving the video and voice via a browser or dedicated application.

The built-in PIR motion sensor provides more reliability than video motion detection, especially in the case of an environment with reflections, objects moving in the wind, moving pets etc. The detection of motion by the PIR sensor can trigger e.g. recording of the video from the camera on a memory card (the camera supports microSD cards up to 128 GB) or by an NVR, or can activate the alarm output.

The camera can be connected wirelessly (Wi-Fi, IEEE802.11 b/g/n) or via Ethernet port. The use of wireless connection is not recommended for applications in professional CCTV systems with video recording, due to a risk of interference and the influence of obstacles. The wireless connection is convenient in the case of live monitoring and videoconferencing.

The model belongs to a new series, EasyIP 2.0plus, that can be placed somewhere between Easy IP 2.0 a Easy IP 3.0. The cameras of the series support modern compression methods (H.265+/H.265/H.264+/H.264), has housings like the EasyIP 3.0 series, including EXIR IR illuminators. The models with fixed or variable focal length use 1/2.7", 1/2.8" or 1/3" image sensors with 2, 4, 6 or 8 MP resolution. The integrated image analysis functions (VCA) including face recognition, intrusion and line crossing detection, allow for applications in advanced video surveillance projects.

The camera implements several video compression methods, H.265+, H.265, H.264+, H.264, MJPEG. Compared with H.264, H.265 can reduce by half the data stream, which translates into proportional savings of the disk space or into extended data retention time. H.265+ and H.264+ are Hikvision standards based on the original systems and optimized for CCTV applications. They further minimize the streams in typical video surveillance scenarios. With the advanced video compression algorithms, the camera can be used in IP CCTV systems based on modern NVRs implementing H.265 standard (the DS-76/77/96NI-I/K series supports H.265+, H.265, H.264+, H.264). Of course, the camera can also operate with older models supporting H.264 (the DS-76/77NI-E series supports H.264+, H.264).

With the support of ANR (Automatic Network Replenishment), each the IP camera equipped with a memory card can record video in the absence of network connection. After the restoration of the network connection, the recordings are automatically synchronized with those recorded on the NVR. This ensures continuous coverage of events, even in the case of communication problems between the camera and NVR.

The iVMS 4200 client software enables users of HIKVISION devices to manage them in IP networks. The software allows for configuration and management of NVRs/DVRs, IP and analog cameras (in hybrid systems). The iVMS 4200 utility can remotely manage up to 256 devices, with the use of up to 4 monitors. One monitor can display up images from up to 64 cameras. Aside from system configuration and live monitoring, the utility can be used for remote playback, notifying, two-way audio transmission, creating multi-level e-maps.

Hik-Connect is a mobile application, intended for smartphones running Android or iOS operating systems. It can be used for remote live viewing of images from DVRs, NVRs, network cameras via Wi-Fi, 2G or 3G networks, and for playing back recorded video files. The application connects with the devices by IP addresses and/or through the P2P cloud.

Hik-Connect is also a network service for Hikvison devices. The service is based on data processing in the cloud and integrates the following functions:

SADP (Search Active Device Protocol) is a free and simple to use utility for searching Hikvision IP cameras and Hikvision DVRs/NVRs in the local network. The network device search tool can also be used for modification of network parameters of the Hikvision devices, including the change of passwords or recovery of default passwords. Detailed information on the software and its use is contained in the SADP application - LAN tool for organizing CCTV systems based on Hikvision devices article.
