Hikvision DS-7732NI-M4/16P 32-Channel 8K PoE NVR with Dual HDMI and 4 SATA

The DS-7732NI-M4/16P supports up to 32 IP camera inputs, which makes it a strong fit for medium to larger surveillance systems. The datasheet also states it supports up to 32 MP resolution cameras, and after ultra HD resolution mode is enabled, it supports up to 8 channels of 32 MP or 24 MP IP video inputs. That matters because buyers often want to know whether the recorder can handle both a high camera count and higher-resolution cameras at the same time. Online listings and the official product page consistently position camera capacity as one of the main reasons people consider this model.

Yes. This model includes 16 independent PoE network interfaces, each using RJ-45 10/100 Mbps self-adaptive Ethernet, and the datasheet lists PoE power up to 200 W total with IEEE 802.3 af/at support. That is important because it can simplify installation by letting compatible cameras receive power and network connectivity through the recorder itself. For many buyers, that means less extra hardware to plan for and a cleaner install overall. PoE is one of the most commonly highlighted features online for this specific model, especially for users comparing it against non-PoE NVRs.

Yes. HDMI 1 supports up to 8K at 7680 × 4320/30Hz, while HDMI 2 supports up to 4K output. The datasheet also notes that when HDMI 1 is set to 8K, the maximum HDMI 2 output resolution becomes 1080p. Buyers ask this often because display flexibility is a major selling point when the recorder is being used in a monitoring room or where high-detail live viewing matters. The official product pages also emphasize 8K and dual 4K output as key headline features.

The recorder supports H.265+, H.265, H.264+, and H.264 formats, with recording resolutions up to 32 MP. Its decoding capability is listed as 2-ch at 32 MP plus 2-ch at 8 MP, or 10-ch at 8 MP, or 20-ch at 4 MP, or 40-ch at 1080p, all at 30 fps depending on the viewing scenario. That gives buyers a clearer picture of what the unit can realistically display and play back, not just what it can technically accept. This is one of the top questions people ask online because decoding performance affects how smooth the system feels during live view and playback.

The datasheet says the DS-7732NI-M4/16P has 4 SATA interfaces and 1 eSATA interface. It supports up to 16 TB capacity for each disk, which means it is built for serious recording storage compared with smaller desktop units. Buyers usually ask this because storage size directly affects how long footage can be retained before it gets overwritten. The official product materials also highlight H.265+ compression, which helps reduce storage usage by up to 75%, making the available drive space go further. 

No. The datasheet specifically lists the RAID type as “N/A” for the DS-7732NI-M4/16P. That is an important detail because some buyers assume a larger 32-channel NVR automatically includes RAID, but this particular model does not. If storage redundancy is a requirement, this is something to confirm before purchase instead of assuming it is built in. RAID support is a common comparison point online, especially when buyers are looking at multiple Hikvision NVR models in the same family.

Yes. The datasheet lists Hik-Connect and DDNS for easier network management, and it also supports web access without a plug-in. It supports a wide range of network protocols as well, including TCP/IP, DHCP, IPv4, IPv6, DNS, DDNS, NTP, RTSP, SADP, SMTP, SNMP, NFS, iSCSI, ISUP, UPnP, HTTP, HTTPS, ONVIF, and OTAP. That matters because buyers often need remote viewing, management, and compatibility with existing IP camera environments. Online product pages also highlight smooth streaming technology, which is intended to help live view remain usable under weaker network conditions.

Yes. The datasheet says it supports multiple VCA events and configurable smart camera functions such as motion detection, line crossing, intrusion detection, heat map, ANPR, and people counting. It also supports POS information overlay on live view and playback, along with POS-triggered recording and alarm. That makes it more useful in retail, business, and higher-feature security environments where users want more than just continuous video recording. These analytics-related questions show up often online because buyers want to know whether the recorder can support more advanced camera features they may add later.

It supports 1 audio output channel through RCA and 1 channel of two-way audio using the audio input. The datasheet also lists audio compression support for G.711ulaw, G.711alaw, G.722, G.726, AAC, and MP2L2. That is helpful for users who want audio monitoring or simple talkback capability as part of the surveillance system. Buyers ask this regularly because audio support can be easy to overlook until system planning is already underway.

The DS-7732NI-M4/16P uses a 19-inch rack-mounted 1.5U chassis, so it is intended for structured installs rather than small shelf-only setups. Its dimensions are 440 × 389 × 72 mm, and the weight is listed as 5 kg or less without HDDs. The working temperature range is -10 °C to 55 °C, and power input is 100 to 240 VAC at 50 to 60 Hz. This is a common question online because buyers need to know early whether the recorder fits their rack, cabinet, or control room layout.
