Technical Specifications

Hikvision 16-Channel PoE ColorVu Security Camera System with Microphone and AcuSense 4K NVR

Build a dependable surveillance system around the Hikvision DS-7616NXI-K2/16P(D) 16-channel NVR and DS-2CD1327G0-LUF(C) 2 MP ColorVu turret cameras. The recorder provides 16 built-in PoE ports, AcuSense human and vehicle analysis, up to 4K HDMI output, and space for two hard drives. Each camera captures full-color 1080p video around the clock, includes a built-in microphone, and uses an IP67-rated housing for indoor or outdoor installation.

Resolution clarification: The NVR supports 4K HDMI display output and can record compatible cameras at resolutions up to 12 MP. The included DS-2CD1327G0-LUF(C) camera model has a maximum resolution of 1920 × 1080 (2 MP); it is not an 8 MP/4K camera.

Key Features

16 Plug-and-Play PoE Channels Connect compatible IP cameras to the NVR's 16 independent PoE ports for network data and power through the same Ethernet cable.
AcuSense Human and Vehicle Analysis Device-side Motion Detection 2.0 and perimeter protection can distinguish people and vehicles to help reduce false alarms.
24/7 ColorVu Imaging The cameras combine an F1.0 aperture, high-performance sensor, and white supplemental light to produce vivid color images in extremely low light.
Built-In Camera Microphone The -UF camera configuration captures audio alongside video and supports environmental noise filtering.
4K Recorder Output View the system through HDMI at up to 3840 × 2160 at 30 Hz, with an independent VGA output also available.
Expandable Local Storage Two SATA interfaces accept hard drives with a supported capacity of up to 16 TB per drive.
Efficient Video Compression H.265+ compression can reduce storage use by up to 75%, helping retain more footage with available disk space.
Weather-Resistant Turret Cameras The IP67-rated cameras are protected against water and dust for flexible indoor or outdoor placement.
Wide-Angle Coverage The 2.8 mm version offers a 105.2° horizontal field of view, while the 4 mm option provides a narrower 83.6° view for more focused coverage.
Remote System Access Hik-Connect and iVMS-4200 support convenient live viewing and network management from compatible devices.
