Overview
The Hikvision DS-2CD2146G2-ISU is a 4 MP AcuSense fixed dome network camera for indoor and outdoor surveillance. It combines DarkFighter low-light imaging, true 120 dB WDR, onboard deep-learning AcuSense analytics (human/vehicle classification and face capture), efficient H.265/H.264 compression and an IR illuminator for night operation.

• 4 MP sensor — up to 2688 × 1520 (main stream).
• DarkFighter low-light technology: colour to 0.003 lux; B/W with IR.
• AcuSense deep-learning analytics for human/vehicle classification and face capture to reduce false alarms.
• True 120 dB WDR for high-contrast scenes; built-in IR (≈30 m) and smart supplement light.
• H.265/H.264 (and H.265+/H.264+) for reduced bandwidth and storage; MJPEG on sub-stream.
• PoE (802.3af) or 12 VDC power; metal housing with variant-dependent IP66/IP67 and IK10 ratings.

Use cases: commercial entrances, retail, car parks, building perimeters and other general-purpose outdoor/indoor surveillance where reliable object classification and low-light performance are required.

Compliance & installation: supports ONVIF, Hik-Connect/iVMS and common network security protocols (HTTPS/TLS, IP filtering). Check the supplied datasheet and local regulations for CE/UKCA compliance and installation guidance. For permanent installations we recommend professional installation and correct earthing, and confirm variant-specific IP/IK ratings before installation in exposed locations.
