The NVR4232-16P-EI is a Dahua WizSense 32-channel NVR with 16 PoE ports, designed for professional IP video surveillance systems requiring high recording capacity, direct camera power supply and advanced artificial intelligence functions. It supports IP cameras with resolutions up to 16MP, integrates AI functions directly into the recorder and features 2 SATA ports for hard drives with capacities of up to 20TB each.
The NVR4232-16P-EI allows connection and management of up to 32 IP cameras, making it suitable for businesses, warehouses, commercial buildings, industrial facilities and other professional surveillance systems with a large number of cameras.
The NVR4232-16P-EI features 16 PoE 10/100 Mbps ports compatible with IEEE 802.3af/at standards. These ports allow data transmission and direct power supply to compatible IP cameras through the same network cable, simplifying installation.
The integrated PoE system provides a total power budget of 130 W, with a maximum power output of 25.5 W per port. This capacity allows multiple compatible PoE IP cameras to be powered directly from the recorder.
The NVR4232-16P-EI supports IP cameras with resolutions of 16MP, 12MP, 8MP, 6MP, 5MP, 4MP, 3MP, 1080p, 720p, 960p, D1 and CIF. Compatibility with cameras up to 16MP allows high-resolution systems to be deployed in applications requiring a high level of detail.
The NVR4232-16P-EI integrates WizSense technology and provides face detection, face recognition, perimeter protection and SMD directly through the recorder, allowing intelligent functions to be used at recorder level.
The NVR4232-16P-EI supports recorder-based SMD Plus on 4 channels. This technology performs secondary filtering of people and motor vehicles, helping to reduce false alarms caused by leaves, rain or changes in lighting conditions.
Recorder-based perimeter protection is available on 2 channels, with support for up to 10 IVS rules per channel. With compatible AI cameras, camera-based perimeter protection can be used on all channels.
The NVR4232-16P-EI supports recorder-based face detection on 1 channel, processing up to 12 face images per second. Supported attributes include gender, age group, glasses, expressions, face mask and beard.
The NVR4232-16P-EI supports up to 10 face databases with a total of 20,000 images and a total capacity of 2.5 GB. Information such as name, gender, date of birth, address, ID type and number, country or region and status can be associated with the images.
In addition to the AI built into the recorder, the NVR4232-16P-EI supports AI functions provided by compatible cameras, including face detection, face recognition, perimeter protection, SMD, ANPR, people counting, stereo analysis and heat map.
With AI disabled, the NVR4232-16P-EI provides up to 256 Mbps incoming, 256 Mbps recording and 256 Mbps outgoing bandwidth. With AI enabled, it provides up to 180 Mbps incoming, 180 Mbps recording and 180 Mbps outgoing bandwidth.
With AI disabled, the NVR4232-16P-EI supports decoding of up to 2 channels 16MP@30 fps, 2 channels 12MP@30 fps, 4 channels 8MP@30 fps, 4 channels 6MP@30 fps, 6 channels 5MP@30 fps, 8 channels 4MP@30 fps, 16 channels 1080p@30 fps or 32 channels 720p@30 fps.
With AI enabled, it supports decoding of up to 1 channel 16MP@30 fps, 2 channels 12MP@30 fps, 3 channels 8MP@30 fps, 3 channels 6MP@30 fps, 4 channels 5MP@30 fps, 6 channels 4MP@30 fps, 12 channels 1080p@30 fps, 16 channels 720p@30 fps or 32 channels D1@30 fps.
The recorder supports Smart H.265+, H.265, Smart H.264+, H.264 and MJPEG, helping to optimise bandwidth usage and available hard drive storage space.
The NVR4232-16P-EI features 2 SATA ports, allowing up to 2 hard drives with a maximum capacity of 20TB each. It also supports disk grouping. Maximum supported HDD capacity may vary according to ambient temperature.
The NVR features 1 HDMI output and 1 VGA output. The HDMI output supports resolutions up to 3840 × 2160 (4K), while VGA supports up to 1920 × 1080. Simultaneous or different video sources can be configured for the VGA and HDMI outputs.
The NVR4232-16P-EI supports 1, 4, 8, 9, 16, 25 or 36 divisions on the first screen. The second screen supports 1, 4, 8, 9 or 16 divisions.
The NVR4232-16P-EI supports simultaneous playback of up to 16 channels. Recording modes include general, motion detection, intelligent and alarm recording, while playback modes include instant, general, event, tag and smart playback.
The NVR4232-16P-EI features 1 × RJ-45 Ethernet 10/100/1000 Mbps port and supports ONVIF 23.12 Profile T, Profile S and Profile G, as well as CGI and SDK. It is also compatible with third-party cameras including Panasonic, Sony, Hanwha, Axis, Pelco, Arecont and Canon.
The NVR4232-16P-EI features 4 alarm inputs and 2 alarm outputs, allowing integration of the video surveillance system with external devices and different alarm actions.
The recorder includes 1 RCA audio input and 1 RCA audio output, 2 USB 2.0 ports and 1 RS-232 interface, providing multiple options for system integration and management.
The NVR4232-16P-EI measures 375 × 329.3 × 53 mm, uses a 100–240 VAC, 47–63 Hz power supply and consumes less than 10 W without HDD, excluding power supplied through the PoE ports.
