Hikvision DS-2CD2121G0-I IR Fixed Dome IP Camera

The Hikvision DS-2CD2121G0-I is a 2MP IR Fixed Dome Network Camera designed for dependable 24-hour surveillance in homes, offices, retail stores, warehouses, factories, schools, parking areas, entrances, and other security-sensitive locations.

Equipped with a 1/2.8-inch Progressive Scan CMOS sensor, the camera captures Full HD video at 1920 × 1080 resolution and supports up to 30fps, providing smooth and detailed footage for general surveillance applications.

For challenging lighting environments, the camera uses 120dB WDR, helping balance bright and dark areas in the same scene. It also supports BLC, 3D DNR and ROI to improve image clarity and reduce unwanted image noise.

For nighttime monitoring, the DS-2CD2121G0-I features IR illumination with a range of up to 30 meters. The IR Cut Filter automatically switches between day and night modes to maintain useful surveillance footage in changing lighting conditions.

The camera supports H.265+, H.265, H.264+ and H.264 compression technologies. H.265+ helps reduce bandwidth and storage requirements, making the camera suitable for installations where recording storage efficiency is important.

The DS-2CD2121G0-I supports 2.8mm, 4mm and 6mm fixed-focal lens options. The 2.8mm lens provides a wide viewing angle, while 4mm and 6mm versions offer progressively narrower views for more focused surveillance.

For local recording, the camera includes a microSD/microSDHC/microSDXC card slot, with Hikvision documentation listing support up to 128GB for the B version. Some related DS-2CD2121G0-I(W)(S) documentation lists capacities up to 256GB, so the exact storage capacity should be verified against the supplied regional/version suffix.

The camera supports PoE (IEEE 802.3af) as well as 12V DC power, allowing a single Ethernet cable to carry both network data and power when connected to a compatible PoE switch or NVR.

Its durable housing is designed for demanding installations, with IP67 water and dust resistance and IK10 vandal resistance on the documented G0-I(W)(S) series.
