Dahua NVR4104HS-P-4KS3 - 4 Channel 12MP HDMI 4K NVR Recorder

Dahua NVR4104HS-P-4KS3 4-Channel 12MP HDMI 4K NVR Recorder

Video performance and recording capacity

The device supports a maximum resolution of 12MP, allowing the recording and viewing of very high-definition images, suitable for demanding video surveillance applications. The maximum input bandwidth of 80 Mbps ensures simultaneous support for multiple high-resolution video streams without noticeable degradation in quality. Simultaneous playback of recordings on 1 or 4 channels allows precise control of archived sequences and efficient replay during analysis or investigation operations.

Video outputs and display interfaces

The product is equipped with an HDMI output supporting a resolution of up to 3840x2160, ideal for viewing on 4K monitors, as well as a VGA output offering a maximum resolution of 1920x1080 for wide compatibility with standard displays. Both interfaces enable flexible integration into different control environments, whether as a single supervisory station or a multi-display control room.

Data Storage and Management

The device supports a SATA hard drive with a capacity of up to 20 TB, providing a large storage volume to keep high-definition recordings over long periods of time. This capability allows for fine-tuning of video retention settings, recording quality, and frame rate to meet regulatory or internal archiving requirements.

Power supply and PoE ports

The power supply is supplied in 53 VDC, 1.22 A, for a maximum consumption of 25.5 W, guaranteeing controlled energy efficiency and operating stability. The 4 built-in PoE ports provide direct power to compatible IP cameras, simplifying wiring and reducing the need for separate power supplies. This architecture makes it easy to deploy and maintain the system, while providing centralized data power and transmission.

Video Compression and Bandwidth Optimization

The system supports Smart H.265 Plus, H.265, Smart H.264 Plus and H.264 compression formats, allowing a significant reduction in bandwidth consumption and storage space, without significantly compromising image quality. The "Smart" algorithms dynamically optimize encoding based on scene movement and content, improving the overall efficiency of the system, especially in installations with a large number of cameras.

Artificial Intelligence Features

Each connected camera can benefit from advanced artificial intelligence features, including face detection and recognition, perimeter protection, SMD Plus technology to more reliably distinguish people and vehicles, people counting, stereoscopic analysis, and heat map generation. These features allow for in-depth scene analysis, a reduction in false alarms and a finer use of video data for security, management of people flow or space optimization.

Advanced control and operation features

The system supports the EPTZ function for electronic zoom and framing control of high-resolution images, allowing you to focus on specific areas of interest without the need for a motorized dome. The one-click arming and disarming feature simplifies day-to-day operational management, making it easy to quickly enable or disable monitoring scenarios and alarm rules based on schedules and needs.

Network Connectivity and Protocols

The logger has a 10/100M RJ45 network port for connection to the local network and, if necessary, to remote systems for remote monitoring, replay, or maintenance. It complies with ONVIF 22.12 standards (Profiles T, S, G), as well as CGI and SDK protocols, ensuring broad compatibility with many brands of IP cameras and third-party video management or system integration software.

Audio Interfaces and System Integration

1:1 audio inputs/outputs allow a microphone and speaker to be connected, providing the ability to perform live listening, video-synchronized audio recording, or remote voice announcements. This feature enhances the system's interaction and deterrence capabilities, as well as the quality of evidence by combining sound and image during critical events.

Mechanical and environmental characteristics

With dimensions of 26 cm x 23.2 cm x 4.7 cm in a compact 1U format and a weight of only 0.87 kg, the device fits easily into cabinets, on a desk or in small technical cabinets. The operating temperature range of -10°C to 55°C ensures high reliability in a variety of environments, whether in technical rooms, control rooms or industrial sites with suitable ventilation.
