As highlighted on page 1 of the datasheet, this capability ensures enhanced image detail, making it easier to identify objects and individuals in large monitoring areas. Integrated PoE for Simplified Deployment One of the standout features of this NVR is its 16 built-in PoE ports, enabling direct connection and power supply to IP cameras without the need for additional switches or power sources. According to the technical section on page 2, the PoE ports comply with IEEE 802.3af/at standards, ensuring reliable power delivery to connected devices. Benefits include: Reduced installation time and cost Cleaner and more organized cabling Centralized power management High-Efficiency Video Compression with H.265 The system supports H.265 and H.264 compression technologies, significantly improving storage efficiency and reducing bandwidth usage. As described on page 1, H.265 delivers double the compression efficiency compared to older standards, enabling longer recording durations without increasing storage requirements. Powerful Performance with High Bandwidth Processing The NVR supports up to 200 Mbps incoming bandwidth, ensuring smooth handling of multiple high-resolution video streams. Decoding capabilities include: 2 channels at 4K resolution (30fps) 8 channels at 1080p (30fps) This ensures reliable playback and live viewing even in high-demand environments. Intelligent Video System (IVS) for Smart Surveillance The DHI-NVR4216/4232-16P-4KS2 supports advanced Intelligent Video System (IVS) features when paired with compatible IP cameras: Tripwire detection Intrusion detection Abandoned/missing object detection People counting and heat mapping As explained on page 1, the system can also record business analytics data such as facial detection and traffic analysis, enhancing operational intelligence. Reliable Recording with ANR Technology The NVR includes Automatic Network Replenishment (ANR) technology, which ensures no data loss during network interruptions. According to page 1, when the network connection is lost, video is temporarily stored on the camera’s SD card and automatically synchronized back to the NVR once the connection is restored. Flexible Storage & Playback Capabilities The system supports: 2 SATA III HDD slots (up to 6TB per drive) Multiple playback modes (1/4/9/16 channels) Smart search functionality for quick video retrieval Seamless Integration & Remote Access The NVR is compatible with a wide range of third-party devices, including brands like AXIS, Panasonic, Samsung, and Sony, as listed on page 2.
