The Dahua DHI-NVR4232-EI is a 32-channel WizSense network video recorder built for commercial IP surveillance systems. It combines 16MP camera support, dual-HDD storage, 4K display output and intelligent event analysis in a compact 1U chassis.
The current Dahua DHI-NVR4232-EI price in Bangladesh is ৳28,500 at Touch IT. This Dahua 32 channel NVR suits offices, factories, warehouses, shopping centres, schools and apartments that need centralized recording with human, vehicle and face analytics. HDDs and cameras are normally selected separately.
This professional NVR records and displays video from compatible network cameras. Thirty-two channels provide expansion space for multi-floor buildings or outdoor zones. Because it has no built-in PoE ports, cameras require an external PoE switch or another suitable power arrangement.
The DHI-NVR4232-EI accepts up to 32 IP camera streams at resolutions up to 16MP. Installers can combine high-detail cameras at gates or cash counters with standard cameras in general areas. Bandwidth reaches 256Mbps with recorder AI disabled and 180Mbps with AI enabled.
Recorder intelligence includes one-channel face detection and recognition, two-channel perimeter protection and four-channel SMD Plus. Human and vehicle filtering helps reduce alerts from rain, leaves or lighting changes. The face library supports 10 databases and 20,000 images. Compatible cameras can add ANPR, people counting, stereo analysis and heat maps.
With AI disabled, the NVR decodes up to 16 × 1080p, 4 × 8MP or 2 × 16MP streams at 30fps. HDMI reaches 4K and VGA reaches 1080p. Up to 16-channel playback and event, tag and smart search options speed up footage review.
Two SATA ports support up to 20TB per compatible surveillance HDD. Smart H.265+ can reduce bandwidth and storage use with compatible streams. Retention depends on camera count, resolution, bitrate, frame rate and recording schedule, so calculate storage around the required recording days.
ONVIF Profiles T, S and G support compatible third-party cameras, while browser, iOS and Android access enable remote monitoring. RCA audio input/output, four alarm inputs and two outputs provide integration options for audio, sensors and sirens.
