Premium Features Motion An object moves through any part of the scene. Tripwire A target crosses a user-defined line. Intrusion A target enters or exits a defined perimeter. Scene Change A person or object moves the camera to change the scene or covers the camera to obscure the scene. Abandoned/Missing Object A target leaves an object in designated area, or a target removes an object from the same designated area. Advanced Features Facial Detection Detects and captures a snapshot of a human face in a defined area within a scene. Face Recognition Triggers an event if the connected facial recognition camera matches a face to one stored on the camera's database. People Counting Measure the number of customers, visitors or passengers in a surveillance scene. Heat Map Generates a visual representation of data. 1. The recorder SMD functions are available only when connected to a Dahua network camera with SMD functionality. Pair a Smart Motion Detection camera with a Dahua recording device that also offers SMD functionality to take advantage of SMD alarm filtering and object classification when searching and playing back recorded video. Downloads: Data Sheet Quick Start Guide User Manual System Overview Dahua's Pro Series network video recorders offer excellent performance and high recording quality for IP video surveillance applications. For applications where details are critical for identification, this professional NVR provides a powerful processor with up to 4K resolution. Additionally, the NVR features a mouse shortcut operation menu, remote management and control, center storage, edge storage, and back up storage. Designed as a cost-effective and easy to install recorder, this NVR is an ideal addition to any security system that monitors public spaces, water conservancy, transportation, city centers, schools, and financial institutions. The NVR is compatible with numerous third-party devices making it the perfect solution for surveillance systems with or without a video management system (VMS). Its open architecture supports multi-user access and it is compatible with ONVIF 2.4, enabling interoperability when combined with 4K cameras. Functions 4K Resolution 4K resolution is a revolutionary breakthrough in image processing technology. 4K delivers four times the resolution of Full HD 1080p devices and offers superior picture quality and image details. 4K resolution improves the clarity of a magnified scene to view or record crisp forensic video from large areas. Smart Motion Detection Smart Motion Detection, a component of Dahua's Analytics+ technology, improves alarm accuracy and decreases the number of false alarms. The advanced SMD algorithm analyzes a scene for human or vehicle motion, while filtering out other motion due to trees, leaves, animals, weather, and triggers an alarm when detected¹. Intelligent Video System (IVS) Recording With built-in intelligent video analytics, the NVR has the ability to detect and analyze moving objects for improved video surveillance. The NVR provides standard intelligence at the edge allowing detection of multiple object behaviors such as abandoned or missing objects. IVS also supports Tripwire analytics, allowing the camera to detect when a pre-determined line has been crossed, People Counting, ideal for business intelligence, and Facial Detection, for searching or identification of individuals. Dual NIC The NVR offers Dual NICs that support Multi-Address, Fault Tolerance, and Load Balance. Multi-Address allows connection to two different network schemes to separate the camera network from the NVR network. Fault Tolerance allows NVR connections to two different switches on a network; if one switch goes down, the NVR swaps to the secondary switch. Load Balancing requires a connection to a managed switch that can switch the NVR between networks depending on network traffic. Face Recognition The NVR stores face recognition video and data from a dedicated facial recognition camera connected to the NVR. The NVR triggers an event if the recognition database on the camera detects a face match. Heat Map The Heat Map option highlights the areas with the highest concentration of people. This information can then be exported into a customized report to assist in business or forensic analysis. Automatic Network Replenishment Technology (ANR) Network Video Recorders with the ANR function automatically store video data on an IP camera SD card when the network is disconnected. After recovery of the network, the NVR automatically retrieves the video data stored on the camera.
