The Hikvision DS-7732NXI-K4/VPro is a 32-channel 1.5U network video recorder that adopts Hikvision AcuSense technology for accurate perimeter protection with fewer false alarms. AcuSeek and AcuSearch work across all channels with compatible AcuSense cameras, modelling up to 50,000 targets per day for fast footage search. Video is recorded in H.265+, H.265, H.264+ and H.264 at up to 12 MP with 256 Mbps of incoming bandwidth, and decoded at up to 4 channels of 12 MP or 24 channels of 2 MP. Facial recognition with up to 16 face picture libraries holding 50,000 images is built in, alongside Motion Detection 2.0 for human and vehicle recognition. Four SATA bays each take drives of up to 16 TB, with two gigabit network interfaces, 4K HDMI and VGA outputs, 16 alarm inputs, 4 alarm outputs, RS-485 and RS-232 interfaces, USB 3.0 and up to 4 IP speaker inputs.
