Cube IP Camera: Hikvision DS-2CD2421G0-IW (2 MP, 2.8 mm, 0,028 lx, IR up to 10 m, Wi-Fi, PIR, PoE)



The Hikvision DS-2CD2421G0-IW K17161 Cube camera is dedicated for use in CCTV systems based on IP DVRs. This model is based on a quality 2 MP image sensor and offers superior picture with high fidelity of color reproduction and low noise in the absence of lighting. Built in IR illuminator with 10 m range, based on EXIR technology ensures proper operation in low lighting conditions. The built-in passive infrared sensor (PIR) allows for accurate motion detection. Built-in speaker and microphone allow for two-way audio communication. The camera has the option of WiFi wireless IEEE802.11 b/g/n or wired connection. 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. It is designed for indoor uses. The camera can be powered conventionally with 12 VDC or through PoE (compliant with the 802.802.3af standard).

H.265 (+) compression
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.
H.265/H.265+ - higher compression ratios with preserving video quality provided by H.264
iVMS-4200 client software
iVMS-4200 is client software dedicated to the management and supervision of Hikvision security systems, such as DVRs (IP, TurboHD), video intercoms, access control, set-top boxes, etc. The software allows you to easily and conveniently monitor all systems by offering viewing from IP cameras, remote playback of recordings, remote configuration, handling of alarm events, two-way audio transmission, e-map support, recording to a HDD and many more.

Access via P2P cloud - Hik-Connect application
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.

Continuity of recordings guaranteed thanks to the ANR function

The main window of the SADP software
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.
