Hikvision 16-Channel 4K PoE NVR DS-7616NXI-K2/16P(D) with AcuSense

The Hikvision DS-7616NXI-K2/16P is a 16-channel AcuSense network video recorder that combines IP video recording with integrated PoE connectivity and intelligent analytics. Sixteen independent PoE network interfaces allow compatible cameras to connect directly to the recorder, with support for IEEE 802.3af/at and a total PoE power budget of up to 200 W. The NVR handles up to 16 IP camera inputs and provides 160 Mbps of incoming bandwidth. Video can be recorded in H.265+, H.265, H.264+, and H.264 formats, while H.265+ compression can reduce required storage space by up to 75%. This brings camera connectivity, power delivery, recording, and video processing together within the same system.

AcuSense technology adds intelligent analysis directly to the recording platform. Motion Detection 2.0 is available across all channels, while device-based perimeter protection can analyse two channels for human and vehicle recognition to help reduce false alarms. Facial recognition is available for one video-stream channel or for comparison across four channels using face pictures. The recorder can maintain up to 16 face picture libraries containing up to 20,000 images in total. Smart search can locate activity within a selected video area, while smart playback helps focus review on relevant footage. Facial recognition, Motion Detection 2.0, and perimeter protection cannot be enabled simultaneously.

The DS-7616NXI-K2/16P is built to handle recording, playback, local display, and storage within a multi-camera system. Its decoding capacity changes according to whether AI functions are active: with AI disabled, it can decode up to two 12 MP, three 8 MP, six 4 MP, or twelve 1080p streams at 30 fps. With AI enabled, the available combinations are one 12 MP, two 8 MP, four 4 MP, or eight 1080p streams at 30 fps. Up to 16 channels can be played back synchronously, allowing recorded video from the full supported camera count to be reviewed together. HDMI and VGA operate as independent outputs, while HDMI supports resolutions up to 4K.

For local storage, two SATA interfaces accept two HDDs with capacities of up to 10 TB each. A self-adaptive 10/100/1000 Mbps RJ-45 Ethernet interface connects the recorder to the wider network, while Hik-Connect supports network management. The NVR also supports up to 128 remote connections together with ONVIF Profile S/G, SDK, and ISAPI interfaces. Alarm integration is available through four alarm inputs and one alarm output, and audio connections provide an audio output together with two-way audio. Stream over TLS encryption adds protection to video transmission, while the recorder’s 16 PoE interfaces keep camera network connections and power delivery concentrated at the NVR.
