Dahua NVR2104HS-W-4KS2 is Dahua's third-generation network video recorder with an embedded Wi-Fi module to support wireless AP function, support automatic detection and connection of IP camera from Dahua without any operation. In addition, it has two-antenna for a strong wireless network signal. IEEE 802.11 b/g/n (2.4G Hz) Wi-Fi covers the wider and further area. Also, this NVR can support wire IP camera accessing, making the installation more flexible. Without the limitation of the network cable, this NVR is ideal for a wide range of applications such as home safety, cafe, retail, grocery, education, and other industries. It features an open architecture that supports multi-user access and is compatible with ONVIF 2.4 protocol, enabling interoperability with IP cameras. 8MP resolution is a revolutionary breakthrough in image processing technology. 8MP delivers four times the resolution of standard HDTV 1080p cameras and offers superior picture quality and image details. 8MP resolution improves the clarity of a magnified scene to view or record crisp forensic video from large areas. Smart H.265+ is the optimized implementation of the H.265 codec that uses a scene-adaptive encoding strategy, dynamic GOP, dynamic ROI, flexible multi-frame reference structure, and intelligent noise reduction to deliver high-quality video without straining the network. The DMSS app is available on the iOS App Store and Google Play. It makes surveillance easy and simple, allowing you to remotely access NVR devices, view live video, receive event push notifications, and search for recorded videos from an iPhone, iPad, or Android phone at any time from virtually anywhere. It has a 1-year warranty.
