Hikvision 32CH 16 POE NVR 2HDD – DS-7632NXI-K2/16P

The Hikvision DS-7632NXI-K2/16P is a professional-grade 32-channel Network Video Recorder (NVR) designed for large-scale surveillance applications that demand high performance, advanced analytics, and reliable storage. Equipped with 16 Power-over-Ethernet (PoE) ports and support for dual hard drives, this NVR offers exceptional efficiency, making it ideal for commercial buildings, enterprise facilities, retail outlets, educational institutions, and high-security environments.

Intelligent Analytics

The DS-7632NXI-K2/16P goes beyond traditional recording by incorporating advanced artificial intelligence analytics. It supports AI by device and AI by camera, enabling a wide range of features that greatly enhance security and reduce false alarms.

• AI by Device: Built-in analytics include facial recognition, perimeter protection, and motion detection 2.0. With deep learning capabilities, the system can accurately identify human and vehicle targets, minimizing unnecessary alerts caused by moving objects such as leaves, animals, or lighting changes.
• AI by Camera: Expands functionality to include throwing object detection from buildings, automatic number plate recognition (ANPR), and full video content analysis (VCA). These features allow operators to monitor specific events, enforce safety policies, and gain deeper insights into site activities.

Facial Recognition

Facial recognition is one of the standout features of this NVR. It can perform:

• Face picture comparison for access control or identity verification.
• Human face capture for real-time monitoring.
• Face picture search for quick retrieval of recorded footage.

The NVR supports up to 16 face picture libraries with a total of 20,000 images, each up to 4 MB in size. This makes it a powerful tool for organizations that require advanced identity management.

Motion Detection 2.0

With motion detection powered by deep learning algorithms, the NVR distinguishes between humans, vehicles, and irrelevant objects. This reduces false alarms and ensures operators only receive alerts that matter. It supports all channels up to 4 MP video analysis, with enhanced SVC mode extending up to 8 MP for more accurate detection.

Perimeter Protection

The DS-7632NXI-K2/16P offers perimeter defense analytics, designed to monitor restricted zones or sensitive areas. By supporting both device-side and camera-side analytics, it ensures reliable human and vehicle detection across all channels, enhancing site security.

Video and Audio Performance

This NVR supports 32 IP video channels with an impressive 256 Mbps incoming bandwidth and 160 Mbps outgoing bandwidth, ensuring smooth streaming and recording even in high-traffic systems. It provides multiple output options, including:

• HDMI Output: Up to 4K (3840 × 2160) resolution at 30 Hz for crystal-clear monitoring.
• VGA Output: Up to 1080p resolution at 60 Hz.
• Independent HDMI/VGA output for flexible display setups.

Audio is supported with two-way communication through RCA ports, allowing operators to interact with on-site personnel directly via the NVR.

Decoding and Recording

The DS-7632NXI-K2/16P supports multiple decoding formats including H.265/H.265+/H.264+/H.264, delivering efficient compression without compromising quality. Recording resolution supports up to 12 MP, covering a wide range of requirements.

Its decoding capability allows:

• AI on: 1-channel @ 12 MP, 2-channel @ 8 MP, 4-channel @ 4 MP, or 8-channel @ 1080p (all at 30 fps).
• AI off: Expanded capacity up to 12 channels at 1080p, ensuring flexibility depending on the workload.

Storage and Connectivity

The NVR is equipped with 2 SATA interfaces, each supporting up to 10 TB capacity, providing ample storage for continuous recording. Connectivity options include:

• 16 PoE ports compliant with IEEE 802.3af/at, supporting up to 200 W total power for connected IP cameras.
• USB ports (front and rear) for data export and peripheral connection.
• 4 alarm inputs and 1 alarm output for integration with external security devices.

Network Features

The unit supports a wide array of network protocols, including TCP/IP, DHCP, IPv4/IPv6, RTSP, SMTP, SNMP, HTTP, HTTPS, and more. Remote connection supports up to 128 clients, and it is compatible with popular browsers such as IE, Chrome, Firefox, Safari, and Edge.

Build and Reliability

The DS-7632NXI-K2/16P is built in a 1U rack-mountable chassis, measuring 385 × 315 × 52 mm and weighing ≤ 3 kg (without HDD). It operates reliably under challenging conditions, with a working temperature range of -10 °C to 55 °C and humidity tolerance from 10% to 90%.

The system meets strict global certifications including CE, FCC, IC, CB, UL, Rohs, Reach, WEEE, RCM, UKCA, LOA, and BIS, ensuring compliance with international safety and quality standards.

Conclusion

The Hikvision DS-7632NXI-K2/16P is the perfect choice for organizations seeking a future-proof surveillance solution that combines high channel capacity, intelligent video analytics, and reliable storage in one robust device.
