Network Video Recorder DAHUA NVR4116-4KS3 16-channel 4K support

DAHUA NVR4116-4KS3 is a 16-channel network video recorder designed for centralized recording and management of IP camera streams with support for up to 4K resolution. The recorder runs Embedded Linux on an industrial-grade processor and provides web and local GUI interfaces. It supports a wide range of intelligent video functions (by camera and by recorder), multiple video resolutions and compression standards, local storage via a single SATA disk (up to 20 TB per disk depending on temperature), and dual video outputs (HDMI and VGA) for monitoring.

Advantages

The NVR offers AI-assisted features including SMD Plus on the recorder (4 channels) and AI capabilities on cameras (face detection, face recognition, perimeter protection, SMD Plus, people counting, stereo analysis and heat map) with up to six AI channels for camera-based analytics. It supports 16 access channels, multi-channel playback up to 16 channels, flexible video output resolutions including 3840×2160 on HDMI, and broad third-party camera compatibility (ONVIF and major brands). Network interfaces and protocols include Gigabit Ethernet, HTTP/HTTPS, IPv4/IPv6 and mobile access for iOS and Android.

Suitable for

• Small and medium commercial premises requiring centralized 4K recording
• Residential systems where multiple IP cameras need unified management and local playback
• Installations that require AI analytics such as face detection, people counting or perimeter protection

How to use

Install the NVR on a rack or desktop and connect IP cameras via the network port or through a compatible switch. Insert and format a SATA hard disk (up to 20 TB supported per disk, depending on environment) for local recording. Configure network settings and camera streams through the web interface or local GUI, enable desired AI functions per camera or recorder, and set recording modes (general, motion detection, intelligent, alarm). Use HDMI or VGA output for live monitoring and the mobile apps on iOS or Android for remote access.

Usage recommendations

For reliable long-term recording, install the unit in a temperature-controlled environment within the specified operating range, use a compatible enterprise-grade HDD sized appropriately for retention needs, and keep firmware up to date. When enabling AI features, verify network bandwidth and adjust camera resolutions or stream settings to maintain required recording and streaming performance.
