Description
The Dahua NVR4116HS-4KS3 is a 16-channel, premium-quality 1U network video recorder designed for robust, centralized surveillance systems, suitable for homes, shops, and small to medium-sized businesses.
Powered by a reliable industrial-grade processor and embedded Linux, the Dahua NVR4116HS-4KS3 supports IP cameras with up to 12 MP resolution, delivering smooth playback with decoding capability for up to 16 × 1080p streams at 30 fps or 2 × 8MP streams at 30 fps.
It features advanced video compression options including Smart H.265+, H.265, Smart H.264+, and H.264, significantly reducing storage needs and network load while keeping video quality clear. With a bandwidth capacity of 160 Mbps for incoming and recording streams and 80 Mbps for outgoing streams, it delivers stable performance and uninterrupted recording even when multiple cameras are connected at once.
The device includes one SATA interface supporting a hard drive of up to 20 TB capacity, allowing for long-term video storage across an extended recording history without needing a multi-bay chassis.
Integrated with Dahua’s WizSense technology, the Dahua NVR4116HS-4KS3 provides enhanced intelligence that improves accuracy and efficiency in surveillance. The recorder supports 4-channel SMD Plus, which accurately filters human and vehicle targets from irrelevant objects such as leaves, light, or animals, minimizing false alarms.
Compared to the standard 4KS3 model, this HS version enables advanced functions including face detection, perimeter protection with line crossing and intrusion rules, people counting for retail analytics, stereo analysis for behavioral studies, and heat mapping to track density in monitored areas across up to 12 channels when paired with compatible AI cameras.
For playback, users benefit from multiple modes such as instant, event-based, tag-based, or smart search, making it simple to locate critical video segments without scrubbing through long recordings manually.
Video output is straightforward, with 1 HDMI output supporting up to 4K resolution and 1 VGA output available for local display, giving installers flexibility depending on the monitor infrastructure already in place at a given site.
The device is dedicated to working in intelligent IP monitoring systems for medium and small-sized facilities, with 2 USB 2.0 ports for connecting a mouse or external storage, along with a Gigabit RJ45 port for stable network connectivity.
With its compact 1U design, WizSense AI capabilities, and centralized multi-camera monitoring, the Dahua NVR4116HS-4KS3 delivers stable 16-channel recording and efficient storage performance for professional surveillance systems.
