Description
Hikvision DS-2CD2021G1-I(C) is a 2MP cylindrical IP video camera with PoE power support and built-in IVS functions (line crossing detection or intrusion into a specified zone). It is designed for operation in monitoring systems outside buildings and for organizing video surveillance of private territories, warehouses, parking lots, office buildings, museums, banks, etc. When an intrusion is detected in the protected area, an alarm message is sent, which will allow you to react to the event as quickly as possible.
The camera is based on a 1/2.7" Progressive Scan CMOS light-sensitive sensor with a maximum resolution of 1920x1080 pixels. Matrix sensitivity is 0.005 Lux at F1.6 (AGC on) and 0 Lux - with IR illumination.
The camera lens has a fixed focal length of 2.8 mm and provides the following viewing angles:
horizontally - 112°C
vertically - 59°C
diagonally - 134°C
Built-in IR illumination illuminates a distance of up to 30 meters. During installation, the camera position can be changed in three planes: rotation from 0°C to 360°C, tilt - from 0°C to 90°C and rotation - from 0°C to 360°C.
Recording is done in two streams with the following resolutions:
main stream: 1920x1080, 1280x720 (25 fps)
substream: 640x480, 640x360 (25 fps)
RJ45 10/100 interface is used to connect to the network. Internet access allows you to view live video and configure the camera through iVMS-4200, Hik-Connect, Hik-Central or the web interface. For storing video, the camera has a slot for a memory card with a capacity of up to 256 GB.
Power is supplied from a 12V source or via PoE (802.3af).
Functional features of Hikvision DS-2CD2021G1-I(C):
The key feature of the video camera is built-in video analytics functions: triggering an alarm when intrusion and crossing a specified border are detected.
H.265/H.264 codecs compress video, thereby saving space on external storage media, but while maintaining high video quality. Also, modern H265+ and H264+ codecs are available in the main stream.
Video improvement and processing are performed by built-in functions:
wide dynamic range (120 dB)
ROI (1 fixed region for the main stream) - highlighting the area of interest
BLC and HLC backlight compensation
3D noise reduction
The camera has protection against dust and moisture, which meets the international standard IP67. It can operate in a temperature range from -30 to +60°C.
