Product Description
The Dahua DHI‑NVR5232‑EI is a professional‑grade WizSense Series network video recorder designed to handle extensive IP camera deployments. With support for up to 32 IP camera channels and max camera resolutions up to 32 MP, this recorder delivers high‑resolution surveillance and robust performance.
It supports multiple video compression formats such as Smart H.265+, H.265, Smart H.264+, H.264, and MJPEG to improve recording efficiency and save storage space while maintaining clear video quality. With a total network bandwidth of up to 384 Mbps (incoming/recording/outgoing), it can reliably manage large CCTV networks.
Built‑in AI analytics include face detection & recognition, perimeter protection, and Smart Motion Detection (SMD Plus) — helping reduce false alarms and provide meaningful alerts. When paired with compatible AI cameras, additional features like video metadata, ANPR (automatic number plate recognition), stereo analysis, heat map, and people counting are supported.
For local monitoring, the unit includes HDMI (up to 4K) and VGA outputs with multi‑screen display options (up to 36 views on the main screen). Remote access via mobile apps (iOS/Android) or web browsers enables live viewing, playback, and management from anywhere. Compatibility with third‑party cameras via ONVIF further enhances installation flexibility.
