Dahua 16-channel 1U PoE NVR NVR4216-16P-4KS3

The Dahua NVR4216-16P-4KS3 is a professional 16-channel 1U network video recorder with integrated PoE, designed for modern IP surveillance systems that require high image quality, efficient storage, and intelligent analytics. It supports a wide range of advanced video compression formats, including Smart H.265+, H.265, Smart H.264+, H.264, and MJPEG, enabling significant bandwidth and storage savings without compromising image clarity. The recorder delivers strong decoding performance, supporting up to 8 channels of 1080p video at 30 fps or 2 channels of 8 MP video at 30 fps simultaneously. This ensures smooth live view and playback even in high-resolution environments. Compatibility with IP cameras up to 12 MP makes the device suitable for installations where detailed visual information is critical, such as retail, offices, warehouses, and public facilities.

With a maximum incoming, recording, and outgoing bandwidth of 160 Mbps, 160 Mbps, and 80 Mbps respectively, the NVR can handle multiple high-bitrate streams at once, maintaining stable system performance under heavy load. The device supports EPTZ functionality, allowing digital pan, tilt, and zoom on high-resolution footage, as well as one-click arming and disarming, simplifying daily operation for security staff. Multiple output options, including HDMI and VGA, allow flexible connection to monitoring displays, while support for audio input and output enables synchronized audio recording and playback where required. The NVR4216-16P-4KS3 combines powerful processing, modern compression, and flexible system control in a compact 1U form factor, making it a reliable core component for small to medium-scale IP video surveillance systems.

The Dahua NVR4216-16P-4KS3 integrates advanced AI-powered video analytics, enhancing situational awareness and reducing false alarms. The device supports AI by Recorder, enabling Smart Motion Detection (SMD) on up to 4 channels, which intelligently distinguishes between human and vehicle targets and irrelevant motion such as animals, shadows, or weather effects. When paired with compatible Dahua AI cameras, the recorder unlocks the full potential of AI by Camera functionality. This includes face detection and face recognition, allowing systems to identify and compare faces against databases for access control or forensic investigation. Perimeter protection features provide accurate intrusion detection using virtual tripwires and restricted zones, significantly improving perimeter security efficiency.

Additional intelligent functions include people counting, which is valuable for retail analytics and occupancy monitoring, as well as stereo analysis and heat map generation, offering visual insights into movement patterns and area usage. These tools help businesses optimize layouts, improve safety, and make data-driven operational decisions. The recorder also supports SMD by camera, combining edge-based intelligence with centralized management for improved detection accuracy. Alarm handling is enhanced through 4 alarm input channels and 2 alarm output channels, enabling integration with external sensors, sirens, or access control systems. Audio analytics are supported through compatibility with common compression formats such as G.711a, G.711u, PCM, and G726, ensuring synchronized audio-video evidence when microphones are connected. By centralizing AI processing, event management, and alarm handling, the NVR4216-16P-4KS3 significantly reduces operator workload while increasing overall system effectiveness.

The Dahua NVR4216-16P-4KS3 features 16 built-in PoE ports supporting IEEE 802.3af/at, allowing IP cameras to be powered and connected directly through the recorder. Each port delivers up to 25.5 W, with a total PoE power budget of 130 W, reducing the need for external switches or power supplies and significantly lowering installation complexity. The device supports two SATA hard drives, each with a capacity of up to 20 TB, enabling long-term local storage for high-resolution video recordings. This makes the recorder suitable for environments with extended retention requirements. Multiple interface options, including RS-232 and two USB 2.0 ports (one front and one rear), provide flexibility for system expansion, data backup, and peripheral connectivity.

Network connectivity is handled via a Gigabit Ethernet RJ-45 port, ensuring reliable communication with cameras and remote clients. The recorder operates on a 100–240 VAC power supply at 50/60 Hz, with low energy consumption. The NVR itself consumes less than 10 W without hard drives, making it energy-efficient despite its powerful capabilities. Housed in a compact 1U chassis, the recorder measures 375.0 × 327.9 × 53.0 mm and weighs 2.60 kg, allowing easy installation in racks or on shelves. It is designed to operate reliably in temperatures ranging from –10 °C to +55 °C, ensuring stable performance in various indoor environments. Combining robust hardware, integrated PoE, expandable storage, and efficient power management, the NVR4216-16P-4KS3 provides a dependable and scalable foundation for professional IP video surveillance systems.
