Network Video Recorder Hikvision DS-7732NXI-K4(D) — 32ch, 4K, 40 TB, 1.5U, Black

Hikvision DS-7732NXI-K4(D) is a network video recorder in a 1.5U form factor designed for medium to large IP camera deployments. The recorder supports up to 32 input channels and records at a maximum resolution of 3840×2160 (4K). It provides hardware and codec flexibility with support for H.265, H.265+, H.264+ and H.264 formats, and accepts SATA/SATA II/SATA III hard drives with a combined maximum capacity of 40 TB. The device offers Gigabit Ethernet connectivity and a typical power consumption around 20 W, making it suitable for continuous recording, remote monitoring and centralized video management in commercial or institutional environments.

Advantages

The recorder combines multi-channel capacity with 4K recording capability while remaining compact in a 1.5U chassis. Support for modern compression codecs such as H.265 and H.265+ helps reduce storage and bandwidth requirements compared with older formats. A 40 TB maximum internal storage limit allows extended retention periods without immediate reliance on external archiving. Gigabit network interfaces facilitate integration into existing IP infrastructures and remote access solutions. Typical power consumption near 20 W contributes to efficient operation in installations with many devices.

Suitable for

• Medium to large IP camera systems in retail, office or campus deployments

How to use

Install the recorder in a suitable rack space with proper ventilation and connect to the local network using a Gigabit Ethernet port. Populate the drive bays with compatible SATA or SATA II/III hard drives up to the supported combined capacity and configure RAID or storage settings according to your retention and redundancy needs. Add IP cameras through the recorder's management interface using discover or manual IP entry, set recording schedules, alarm linkage and encoding profiles to match desired quality and storage trade-offs. Configure remote access and user permissions as required for monitoring and playback.

Usage recommendations

Choose high-reliability surveillance-grade SATA III drives and configure appropriate data redundancy if uninterrupted recording is critical. Use H.265/H.265+ encoding for cameras supporting those codecs to optimize storage usage while maintaining 4K image quality. Ensure adequate network bandwidth and switch capacity when connecting multiple 4K streams, and perform regular firmware updates and maintenance checks to ensure stable operation.
