Technical Specifications

Hikvision 32-Channel 16-PoE 4K NVR System with 4MP ColorVu Bullet Cameras

Build a scalable video-surveillance system around the Hikvision DS-7732NXI-K4/16P(D) AcuSense NVR and DS-2CD1047G0-LUF(C) 4MP ColorVu bullet cameras. The recorder supports up to 32 IP-camera channels, while 16 integrated PoE ports simplify power and network connectivity for compatible cameras.

ColorVu technology delivers vivid full-color imaging around the clock, while the camera's F1.0 aperture, 120 dB WDR, built-in microphone and up-to-30-meter white supplemental light help capture more useful visual and audio evidence. AcuSense human and vehicle classification, Motion Detection 2.0, 4K HDMI output and space-saving H.265+ compression make the system suitable for demanding residential and commercial installations.

The NVR can be expanded with additional compatible IP cameras and up to four SATA hard drives, allowing the system to grow as surveillance requirements change.

Ideal Applications and Common Uses

  • Homes requiring full-color exterior video and recorded audio at selected camera locations
  • Retail stores, showrooms and offices requiring centralized multi-camera recording
  • Warehouses and commercial properties that may expand beyond the first 16 cameras
  • Parking lots, entrances, loading zones, walkways and perimeter areas with suitable supplemental lighting conditions
  • Installations requiring human and vehicle classification to reduce irrelevant motion alerts
  • Properties requiring 4K local monitor output and simultaneous multi-channel playback
  • Sites that benefit from built-in PoE connections and simplified network-camera installation
  • Applications requiring local NVR recording without depending exclusively on cloud storage
  • Indoor or outdoor locations where IP67 weather resistance is appropriate
  • Environments that do not require specialized anti-corrosion protection

Important Configuration Notes

```
Camera Quantity
The NVR supports up to 32 IP-camera channels, but the exact number of cameras supplied in this lot must be confirmed from the selected package configuration.
Direct PoE Capacity
The recorder provides 16 built-in PoE ports. Additional compatible network cameras beyond those ports require suitable external network and PoE equipment.
Hard Drives
The datasheet defines supported SATA capacity but does not confirm that hard drives are included in the lot.
Analytics Compatibility
Certain AI-by-camera features require cameras that independently support those analytics. Do not assume every listed NVR analytic is provided by the DS-2CD1047G0-LUF(C) camera.
Audio Notice
Audio recording must be used in accordance with applicable privacy and recording-consent laws.
