32-channel 1.5U K-Series AcuSense 4K NVR with dual Gigabit Ethernet interfaces, four SATA bays (up to 10 TB each), and comprehensive AcuSense deep-learning analytics. It records up to 12 MP, outputs 4K via HDMI, and supports 256 Mbps incoming bandwidth. AcuSense provides human and vehicle classification on all channels via Motion Detection 2.0, perimeter protection on 2 channels, and face recognition (1-ch video stream or 4-ch face pictures). AI by Camera adds video structuralization, VCA, ANPR, and throwing-objects detection. Dual LAN interfaces, 2× RS-485 + 1× RS-232 serial ports, 16 alarm inputs and 4 alarm outputs (optional 16/9), and TLS-encrypted stream transmission round out the feature set. The /16P variant adds 16 built-in PoE ports (≤ 200 W).
