Hikvision DS-2CD2421G0-I IP Camera for Professional Video Surveillance

The Hikvision DS-2CD2421G0-I is a compact 2 MP IP camera designed for video surveillance in residential settings, small offices, and controlled access points. Commonly deployed in entry-level PoE security systems, it delivers 24/7 recording with H.265+ compression, built-in IR night vision, and two-way audio in a miniaturized form factor.

The 2 MP sensor provides Full HD resolution with sufficient detail for person and event identification in small-area coverage. H.265+ encoding reduces storage and bandwidth requirements compared to H.264, a practical advantage in NVR setups with limited capacity. The integrated IR illuminator covers up to 10 meters in complete darkness, and the built-in microphone and speaker enable real-time two-way communication without external audio hardware.

Single-cable PoE installation simplifies deployment in locations without nearby power outlets, reducing cabling complexity. The camera integrates with the Hikvision ecosystem — compatible NVRs, the Hik-Connect platform, and mobile applications — supporting remote live view and playback from any device. Motion detection with e-mail alerts enables event-driven notification without continuous operator monitoring.

Well suited for residential properties, reception areas, retail outlets, small offices, and storage rooms where a compact, straightforward installation with remote management capability is required. The miniaturized design and PoE support also make it a practical option for expanding existing Hikvision systems without additional infrastructure investment.
