Hikvision DS-7604NXI-K1/4P/VPro | 4-Channel 4K AcuSeek K VPro NVR | AcuSearch, 12MP Decoding, 40Mbps Bandwidth
Summary
The Hikvision DS-7604NXI-K1/4P/VPro is a compact 4-channel PoE AcuSense 4K Network Video Recorder designed for small to medium security installations requiring intelligent video analytics without compromise. Built on Hikvision’s industry-leading AcuSense technology, this NVR delivers accurate human and vehicle detection to dramatically reduce false alarms and minimise the burden on security personnel.
Featuring 4 built-in Power-over-Ethernet ports, the DS-7604NXI-K1/4P/VPro enables true plug-and-play camera deployment — no separate PoE switch required. Cameras are automatically detected and configured, simplifying installation and reducing setup time. With support for resolutions up to 12 MP and 4K HDMI video output, the system delivers exceptional image clarity for live viewing and playback.
Advanced AI capabilities include facial recognition supporting up to 50,000 face pictures across 16 libraries, perimeter protection with line crossing and intrusion detection, AcuSeek for rapid target retrieval, and Motion Detection 2.0 for intelligent human and vehicle classification. H.265+ compression ensures efficient use of storage, supporting HDDs up to 16 TB via the onboard SATA interface. Remote access and management is made simple through the Hik-Connect platform.

FAQ
How many cameras can be connected to this NVR?
The DS-7604NXI-K1/4P/VPro supports up to 4 IP cameras via its 4 built-in PoE interfaces. Cameras are automatically detected and configured when connected, enabling true plug-and-play installation without the need for an external PoE switch.
What is the maximum resolution supported for recording and live view?
The NVR supports recording resolutions up to 12 MP and provides a 4K (3840×2160 @ 30 Hz) HDMI output for live viewing. Simultaneous VGA output is also available, supporting up to 1080p resolution.
How does the facial recognition feature work and how many faces can it store?
The NVR supports facial recognition for video streams (2-ch) or face pictures (4-ch). It can store up to 50,000 face pictures across up to 16 separate face picture libraries, with a total library capacity of 800 MB. Features include face picture comparison, human face capture, and face picture search.
Does this NVR require AcuSense-compatible cameras to use AI features?
Some AI features can be processed directly by the NVR (AI by NVR), including perimeter protection, facial recognition, and Motion Detection 2.0 — these work with standard HD cameras. However, AcuSeek and AcuSearch require connected cameras to support and have enabled Hikvision’s AcuSense function to achieve full performance, including modelling up to 50,000 targets per day.
What storage capacity does this NVR support?
The NVR features 1 SATA interface supporting a single HDD with up to 16 TB capacity. H.265+ compression helps reduce storage requirements by up to 75% compared to standard H.264, maximising the available storage duration.
Can I access this NVR remotely?
Yes. The DS-7604NXI-K1/4P/VPro supports remote access via the Hik-Connect platform for easy network management and live viewing. It supports a wide range of network protocols including TCP/IP, DHCP, IPv4, IPv6, RTSP, SMTP, HTTPS, and more, with support for up to 128 simultaneous remote connections.
