Hikvision DS-2CD1121G0-I - White - Description

 2.8 mm 2 MP Fixed Dome Network Camera

High-Quality 2 MP Imaging for Clear Surveillance:

The Hikvision DS-2CD1121G0-I is a high-performance 2 MP Fixed Dome Network Camera designed for reliable security monitoring. With a 1/2.9" progressive scan CMOS sensor, it captures crisp images at a maximum resolution of 1920 × 1080. This full HD quality enables users to monitor important details clearly, making it ideal for residential, commercial, or office installations. The minimum illumination rating of 0.01 Lux (Color) and 0 Lux with IR ensures excellent low-light performance, complemented by an IR cut filter for true day and night functionality.

Wide-Angle Fixed Lens and Flexible Adjustment:

Equipped with a 2.8 mm fixed focal lens, the DS-2CD1121G0-I offers a wide horizontal field of view (FOV) of 101°, vertical FOV of 56°, and diagonal FOV of 118°. This makes it suitable for covering broader areas with fewer blind spots. The M12 lens mount and fixed F2.2 aperture provide consistent focus, while the adjustable pan (0°–355°) and tilt (0°–75°) allow for precise directional setup during installation.

IR Night Vision and Smart Supplement Light:

To maintain visibility in total darkness, the camera includes an IR illuminator with a range of up to 20 meters. The 850 nm IR wavelength ensures subtle yet effective night imaging. Smart IR technology adapts the intensity of the illumination depending on the subject’s distance, avoiding overexposure and maintaining clear details at night.

Efficient Video Compression and Streaming:

Supporting multiple compression formats including H.265+, H.265, H.264+, and H.264, the DS-2CD1121G0-I minimizes bandwidth and storage usage without compromising video quality. The main stream records at 1080p or 720p up to 30 fps, and the sub-stream supports 640 × 480 and 640 × 360 resolutions. Users can select between constant bit rate (CBR) and variable bit rate (VBR) modes for better storage efficiency.

Secure Network Integration and Remote Access:

The camera features robust network protocols such as TCP/IP, HTTP, RTSP, and more, ensuring seamless integration into existing systems. With support for up to 32 users and user levels (admin, operator, user), it is easy to manage access securely. Remote viewing is possible through iVMS-4200 and compatible browsers like Chrome, Firefox, and Edge, making surveillance accessible anytime, anywhere.

Advanced Image Enhancements and Event Detection:

Image quality is enhanced with features like Digital WDR, 3D DNR, BLC, and HLC. These adjustments help in dealing with complex lighting conditions, ensuring clear visuals in every scenario. Motion detection and exception alerts notify users promptly, with instant linkage to surveillance centers for quick response.

Durable Design with Easy PoE Installation:

Housed in a compact plastic dome, this camera is built to endure challenging environments with operational temperatures ranging from -10 °C to 40 °C and up to 95% humidity. Power options include 12 VDC input or convenient IEEE 802.3af PoE support, simplifying installation and reducing cable clutter. The lightweight form factor (approx. 240g) further aids in quick ceiling or wall mounting.

International Standards and Compliance:

The DS-2CD1121G0-I complies with multiple international certifications for safety (CE-LVD, CB), EMC (CE-EMC), and environmental standards (RoHS, WEEE, REACH). It also includes essential features like password protection, mirror image, heartbeat, and secure reset via email for added operational reliability.
