Product Description
Hikvision DS-2CD2421G0-IW(2.8mm)(W)
With WDR technology, the camera can automatically adjust exposure, eliminating overexposure and underexposure, ensuring clear images in both bright and dark areas.
The 2.8mm (F2.0) lens provides a wide field of view, ideal for monitoring large spaces. The camera supports various operating modes, including Day/Night, which automatically switches between daylight and nighttime, ensuring continuous image continuity without interruption.
The built-in IR illuminator with a range of up to 10m allows for clear vision in the dark, which is crucial for ensuring complete 24/7 surveillance.
The Hikvision DS-2CD2421G0-IW(2.8mm)(W) also offers advanced audio features, including G.711/G.722.1/G.726/MP2L2/PCM/MP3 compression and environmental noise filtering.
This ensures clear and crisp audio in every situation. The camera also supports local storage or network-attached storage (NAS) for secure video storage.
Support for TCP/IP, ICMP, DHCP, DNS, DDNS, RTP, RTSP, NTP, UPnP, SMTP, IGMP, IPv6, and UDP protocols, the camera is compatible with a wide range of systems and devices.
The Hikvision DS-2CD2421G0-IW(2.8mm)(W) also offers advanced security features, such as HTTPS encryption, basic and digest authentication for HTTP/HTTPS, and WSSE and digest authentication.
for ONVIF. This means you can be sure that your data is protected against unauthorized access.
