Product Overview

The Dahua NVR5232-XI/Pro is a compact 1U 32-channel WizMind NVR designed for medium and large commercial surveillance scenarios, including office parks, parking lots, factory campuses, industrial workshops and residential compounds. Equipped with an industrial-grade embedded processor and independent Xinghan large-scale AI algorithm engine, this recorder supports dual intelligent computing modes: Recorder-side AI calculation and Camera-side AI analysis. It integrates face recognition, perimeter IVS, AcuPick WizSeek, SMD false alarm filtering, vehicle metadata and ANPR license plate comparison, with up to 40×1080p@30fps maximum decoding capacity and 8K ultra-high-definition HDMI local output.
