Description
The Dahua NVR5232-EI is a powerful 32-channel network video recorder built on Dahua’s WizSense technology, housed in a compact 1U chassis with support for 2 hard drives, offering intelligent, simple, and inclusive video surveillance solutions.
Supporting Smart H.265+, H.265, Smart H.264+, H.264, and MJPEG decoding formats, the Dahua NVR5232-EI delivers maximum decoding capability of 32 channels at 1080p@30fps or 32 channels at 2MP@30fps, along with up to 384 Mbps of incoming, recording, and outgoing bandwidth, ensuring smooth, unimpeded video streams across the connected camera network.
WizSense focuses on human and vehicle detection with high accuracy, enabling users to act fast on defined targets, and is based on Dahua’s advanced deep learning algorithms for intelligent, simple video surveillance.
AI by Recorder capabilities include 2-channel face detection and recognition supporting up to 20 face databases and 20,000 face images, 4-channel perimeter protection with 10 IVS rules per channel, and 8-channel SMD Plus, which applies secondary filtering for humans and vehicles to reduce false alarms.
When paired with compatible cameras, AI by Camera extends functionality further, supporting face detection and recognition, video metadata for humans and vehicles, perimeter protection, SMD Plus, stereo analysis, crowd distribution, people counting, ANPR, vehicle density, and heat mapping, along with PPE detection, smart object detection, and smart sound detection.
Storage flexibility is a key strength of the Dahua NVR5232-EI, supporting IP cameras with resolutions up to 32 MP, along with AcuPick support across up to 16 channels and N+M cluster/iSCSI compatibility for extended scalability. The NVR supports up to 2 SATA hard drives, each with a maximum capacity of 16 TB.
Connectivity is comprehensive, with simultaneous HDMI (4K) and VGA outputs for local display, 1 USB 2.0 port, 1 USB 3.0 port, 1 RS232 port, and 1 RS485 port, giving the device broad integration options with existing surveillance infrastructure.
EPTZ support and one-click arming and disarming allow administrators to respond quickly to security events, while a dedicated mobile app enables remote viewing and receiving of alarm notifications, keeping users informed while away from the site.
With its AI-driven WizSense features, high channel and bandwidth capacity, and flexible dual-bay storage options, the Dahua NVR5232-EI is a strong choice for businesses building out reliable, intelligent video surveillance infrastructure.
