Hikvision DS-2CD1021G0-I(4mm) – 2MP Fixed Bullet Network Camera

The Hikvision DS-2CD1021G0-I(4mm) is a reliable 2MP Fixed Bullet Network Camera designed to provide clear Full HD surveillance for residential, commercial, office, retail, educational, and outdoor security applications. Combining a 2MP Progressive Scan CMOS sensor, 4mm fixed lens, infrared night vision, H.265+ video compression, DWDR, PoE connectivity, and IP67 protection, the Hikvision DS-2CD1021G0-I(4mm) delivers dependable surveillance performance in a compact bullet housing.

The Hikvision DS-2CD1021G0-I(4mm) captures video at a maximum resolution of 1920 × 1080 pixels, providing detailed Full HD images for everyday security monitoring. The 4mm fixed lens gives the Hikvision DS-2CD1021G0-I(4mm) an approximately 80° horizontal field of view, making it particularly suitable for monitoring entrances, corridors, driveways, gates, storefronts, and other areas where a more focused viewing angle is preferred.

For nighttime surveillance, the Hikvision DS-2CD1021G0-I(4mm) uses infrared illumination to provide visibility in low-light and completely dark environments. The 4mm version offers an infrared range of up to 20 metres, helping maintain useful surveillance after sunset. citeturn1search6turn1search10

The Hikvision DS-2CD1021G0-I(4mm) also features DWDR, which helps balance bright and dark areas within the same scene. Additional image technologies such as BLC, HLC, and 3D DNR help improve image quality when the camera encounters strong backlighting, bright light sources, or image noise.

With support for H.265+, H.265, H.264+, and H.264, the Hikvision DS-2CD1021G0-I(4mm) efficiently compresses surveillance footage while helping reduce network bandwidth and storage requirements. This makes the Hikvision DS-2CD1021G0-I(4mm) a practical choice for installations requiring continuous recording without unnecessarily large storage demands.

Installation is simplified through Power over Ethernet (PoE). The Hikvision DS-2CD1021G0-I(4mm) can receive power and transmit network data through a single Ethernet cable, reducing cabling requirements and making deployment easier with compatible PoE switches and NVRs. The camera also provides a 10/100 Mbps network interface.

Built for outdoor environments, the Hikvision DS-2CD1021G0-I(4mm) features an IP67-rated enclosure, providing protection against dust and water. Its adjustable pan, tilt, and rotation mechanism allows installers to position the camera accurately toward the required surveillance area. citeturn1search3
