Specifications<\/div>\n
Dahua NVR IP 4PoE 4 channels 1U 8MP 2HDDs NVR4204-P-4KS2-L supports 4K and H.265 encoding technology with excellent performances at an affordable price. For applications where a lot of detail is required in the image, this NVR offers 4K resolution processing capacity and can be used as edge storage, central storage or backup, with an intuitive operating menu for remote management and control. NVR4204-P-4KS2-L is ideal for a wide range of applications in video surveillance of schools, financial institutions, transportation, city centers and more. The NVR is compatible with numerous third-party devices, which is why it is the perfect solution for surveillance systems that operate independently of the video management system (VMS). Automatically filters out false alarms caused by animals, rustling leaves, bright lights, etc. It allows the system to perform secondary target recognition and improves the accuracy of alarms. Face detection detects whether there is a human face in the video. This technology adopts an advanced deep learning algorithm to support face detection, tracking, optimization and capture, and then produces the best best face snapshot.
\n 
\nWith an intelligent algorithm, Dahua Smart Motion Detection technology can classify targets that trigger motion detection and filter the alarm triggered by unconcerned targets to return effective and accurate results. With deep learning algorithm, Dahua People Counting technology can track and process human body moving targets to make accurate statistics on the number of entrances, exits and the number of people in the area. The management platform produces annual\/monthly\/weekly\/daily reports. With the advanced scene-adapted rate control algorithm, Dahua smart Dahua technology realizes encoding efficiency superior to H.265 and H.264, provides high-quality video, and reduces storage and transmission costs. The DMSS app is available on the iOS App Store and Google Play. The surveillance app is easy, simple, and allows remote access to back-end devices, view live video, receive push notifications of events, and search for recorded video from an iPhone, iPad, or Android phone, anytime and virtually anywhere.<\/div>\n
