Description
The Dahua NVR5432-EI is a high-capacity 32-channel network video recorder built on Dahua’s WizSense technology, designed to support extensive surveillance systems for public safety, transportation, education, and financial institutions. Its compact chassis supports up to 4 hard drives, giving it solid onboard storage for demanding recording workloads.
Supporting Smart H.265+, H.265, Smart H.264+, H.264, and MJPEG decoding formats, the Dahua NVR5432-EI delivers maximum decoding capability of 32 channels at 1080p@30fps, along with up to 384 Mbps of incoming, recording, and outgoing bandwidth, ensuring smooth, unimpeded video streams across a large camera deployment.
WizSense is an innovative artificial intelligence technology built into the Dahua NVR5432-EI, focusing on human and vehicle detection with high accuracy so users can act quickly on defined targets. The series adopts an independent AI chip and deep learning algorithm to deliver intelligent, simple, and inclusive surveillance solutions.
AI by Recorder capabilities include 2-channel face detection and recognition, 4-channel perimeter protection with 10 IVS rules per channel, and 8-channel SMD Plus, which categorizes targets that trigger motion detection and filters out false alarms caused by animals, rustling leaves, and bright lights.
When paired with compatible cameras, AI by Camera extends functionality further, enabling ANPR, heat maps, people counting, video metadata, and stereo analysis. Dahua’s heat map technology displays crowd density and appearance probability, while ANPR uses deep learning to recognize vehicle number plates and supports blocklist/allowlist searching of target vehicles in recorded video.
Connectivity on the Dahua NVR5432-EI is comprehensive, with 2 HDMI (4K) outputs, 2 VGA outputs, 2 Gigabit RJ45 ports, USB 2.0 and 3.0 ports, an RS232 port, and an RS485 port, along with 16 alarm inputs and 6 alarm outputs, giving it broad integration options with existing surveillance infrastructure.
Remote Management facilitates P2P remote surveillance, allowing video playback on mobile devices via the DMSS app, compatible with both Android and iOS, so administrators can monitor and manage the system from virtually anywhere.
Compatibility with ONVIF ensures the recorder works well with a wide range of third-party devices, making it a strong solution for surveillance systems that integrate with Video Management Software (VMS) platforms.
With its AI-driven WizSense features, high channel and bandwidth capacity, and flexible connectivity, the Dahua NVR5432-EI is a cost-effective and reliable choice for businesses building out comprehensive surveillance infrastructure.
