Dahua N42B2P Lite Series 8-channel 4K Network Video Recorder

1U 8-port PoE 4K and H.265 Lite Network Video Recorder

System Overview

Dahua's Lite 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

Dewarping Mode

The NVR has the ability to correct the distortion in a circular panoramic view produced by a fisheye lens. The NVR offers various dewarping modes for different installations and configurations.

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.

Intelligent Video System (IVS) Recording

Working with IVS-enabled IP cameras, the NVR recognizes and records video that contains IVS data on all IP channels. The NVR records standard intelligence at-the-edge features, as well as premium IVS features that detect abandoned or missing objects, Tripwire violations, and intrusion violations. The NVR is also capable of recording business analysis data – Facial Detection, People Counting, and Heat Map – from IP cameras with built-in Intelligent Business Analytics.

IVS Features:

Standard Features: Tampering with the camera, Camera loses or changes focus drastically, Error writing to an onboard Micro SD card, Error sending or receiving data over the network, Unauthorized access to the camera.
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), People Counting (Measure the number of customers, visitors or passengers in a surveillance scene), Heat Map (Generates a visual representation of data).
