DS-2CD2D45G2-U Hikvision Box IP Camera
Product Overview
The Hikvision DS-2CD2D45G2-U is a 4 MP mini bullet-style network (IP) camera designed for clear, high-detail monitoring. It uses a 1/3″ progressive scan CMOS sensor with a maximum resolution of 2688 × 1520. Video performance is optimized with efficient H.265/H.265+ compression to help save bandwidth and storage, while maintaining high image quality. For scenes with challenging lighting, the camera supports 120 dB true WDR to provide clearer imaging against strong backlight. Image quality is further enhanced with 3D DNR for cleaner, sharper frames, and BLC/HLC as additional exposure-related controls. The camera supports multiple streams (main, sub and third) and supports H.264/H.265 with SVC, plus ROI to optimize encoding across areas of interest. Networking features include ONVIF compatibility and Hikvision client support (iVMS-4200 and Hik-Connect). Security features include password protection, HTTPS encryption, 802.1X authentication options, and TLS 1.1/1.2/1.3 support. A built-in microphone enables real-time audio security, complementing motion and smart event detection. Event capabilities include motion detection, video tampering, network disconnected, illegal login, and HDD status alarms, plus smart functions like scene change detection and audio exception detection. With a compact aluminum-alloy body and available versions for 2.8 mm and 4 mm lenses, this camera is well-suited to a wide range of indoor or outdoor IP surveillance installations.
