The Dahua DHI-NVR4232-EI is a 32-channel WizSense network video recorder for offices, factories, apartments, retail sites and multi-camera security projects. It combines 256Mbps bandwidth, 16MP IP camera support, 4K display output, two HDD bays and recorder-based AI in a compact 1U chassis.
For buyers comparing the Dahua DHI-NVR4232-EI price in Bangladesh, the current Touch IT price is ৳23,000. This professional 32-channel NVR supports Smart H.265+ compression, face detection and recognition, perimeter protection, SMD Plus, remote viewing and broad ONVIF camera compatibility.
This NVR offers central recording for medium and large IP surveillance systems. Its combination of 32 channels, intelligent event filtering and expandable storage suits organisations that need scalable monitoring without moving to a larger four- or eight-disk recorder.
The recorder connects up to 32 network cameras at resolutions through 16MP, supporting mixed-resolution coverage of entrances, interiors, parking and perimeters.
Incoming, recording and outgoing bandwidth each reach 256Mbps with AI off or 180Mbps with AI on. Calculate camera bitrates, frame rates, remote streams and analytics before installation.
Recorder AI supports one-channel face detection and recognition, two-channel perimeter protection and four-channel SMD Plus. SMD Plus classifies people and vehicles to reduce false alarms. Ten face databases hold up to 20,000 images.
Compatible cameras can supply face analytics, perimeter rules, SMD, ANPR, people counting, stereo analysis and heat maps. Availability depends on camera model and firmware.
With AI off, decoding reaches 16 × 1080p or 4 × 8MP at 30fps. HDMI displays up to 4K, while VGA reaches 1080p for control-room monitoring.
Two SATA bays accept compatible surveillance HDDs up to 20TB each, subject to temperature and compatibility. Smart H.265+, H.265, Smart H.264+, H.264 and MJPEG balance quality and storage.
Gigabit Ethernet enables camera and remote access. ONVIF Profiles S, G and T aid third-party integration. Four alarm inputs, two outputs and RCA audio strengthen a CCTV surveillance system.

The NVR has no built-in PoE switch; cameras need an external PoE switch or separate power. HDDs may be sold separately. Confirm approved drives, camera firmware, AI compatibility, bandwidth and warranty.
AI and decoding share processing resources. Third-party cameras may provide video while some Dahua-specific analytics, audio or configuration functions remain unavailable.
Choose this model when 32-channel capacity, two-disk storage and practical WizSense analytics are required in a compact recorder. It balances intelligent event search, 4K monitoring, high-resolution camera support and professional alarm integration.
