DS-2CD2T46G2H-2I/4I Hikvision Bullet IP Camera
Product Overview
The Hikvision DS-2CD2T46G2H-2I/4I is a 4 MP fixed bullet network camera designed for reliable day and night monitoring. It uses a 1/3″ progressive scan CMOS sensor to deliver a maximum resolution of 2688 × 1520, enabling clear identification in both indoor and outdoor scenes. For low-light performance, the camera is equipped with powered-by-DarkFighter technology and includes an IR illuminator with a wavelength of 850 nm. Depending on the variant, the IR supplement light range supports up to 60 m (-2I) or up to 80 m (-4I), making it suitable for perimeter and long-range visibility.
To handle challenging lighting conditions, the camera features 120 dB true WDR, helping maintain image clarity against strong backlight. Video compression is optimized with H.265+ support to improve bandwidth efficiency while preserving detail. The camera also benefits from AcuSense technology, which uses deep learning algorithms to classify human and vehicle targets for more efficient and effective alarm triggering.
Additional features include IP67 water and dust resistance for harsh environments, smart IR (smart supplement light), and ONVIF/major network capabilities for flexible integration. Event capabilities include motion detection with alarm triggering by specified target types (human and vehicle), perimeter protection functions like line crossing and intrusion, and storage options including microSD (up to 512 GB) and NAS support.
