Hikvision 4K 16-Channel Security CCTV System with 8MP ColorVu Audio Cameras

Built for properties that need detailed video around the clock, this Hikvision IP security system combines the 16-channel DS-7616NXI-K2/16P(D) AcuSense NVR with DS-2CD2387G2-LU 8MP ColorVu turret cameras. The cameras provide 4K imaging, full-color video day and night, built-in microphones, human and vehicle classification, and weather-resistant metal housings. Sixteen integrated PoE ports simplify installation by carrying power and data through compatible Ethernet cabling, while two SATA bays provide flexible local-storage capacity.

Configuration note: The supplied datasheets identify the recorder and camera models but do not specify the number of cameras, hard drives, cables, or other installation materials included in the retail kit. Confirm the package contents before ordering.

Key Features

  • 8MP camera resolution up to 3840 × 2160 for highly detailed 4K surveillance video.
